If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Problem #1: How to network unlock a Galaxy S9 Plus

Hi. I ordered my Unlocked Samsung Galaxy S9 Plus from Samsung.com on April this year. Everything is fine, but I’m not able to make or receive a call since I bought until now. I switched 3 Carriers, brought my phone to Samsung care store to check it out, spending time with all my Carriers to get help with my issue. But my phone still gets the same issue. I just learned from Samsung technical support my phone was locked by US Cellular. I called Samsung, US Cellular and my current carrier T-mobile to unlock it, none of them want to do it. I saw on You tube showed how to unlock phone by paying UnlockRiver.com, so they can give the unlock numbers to unlock my phone. My question is, if I unlock my phone by the way on YouTube, can my phone able to call or receive a phone call? Thanks.

Solution: Carrier-branded devices like the one you have is originally built to work for a particular carrier.  Unlocking your phone does not right away means your phone will be able to use messaging and other network services of the current network you’re in. There are other factors to consider in order to make your device work with another network.

A network unlock code works by modifying some settings on your phone so its default network configuration are changed. This may or may not work. In general, a carrier will only unlock their device once all your obligations to them have been fulfilled. If you have outstanding balance with a carrier, they will demand that you settle it first before they can unlock your phone.

Even if you’ve already fulfilled all obligations and the phone has been network unlocked already, there are other reasons why your phone may not work when used in another network. There’s the factor of hardware incompatibility at play. Not all carriers operate in the same band frequency so phones built for them by Samsung also has specific radios. If the radio in your phone is not compatible with the current frequency of your carrier, your phone won’t be able to work even if it’s been network unlocked successfully. Try to do some research by knowing your device’s radio frequencies and comparing them to the frequency bands of your carrier in your area.

Normally, only carriers are allowed to unlock their devices but there are many third party shops both online and offline that can do the job. Be sure to dig deeper into the company that you want to get help from to see if they offer reputable service. Some of them can’t do anything if you have a CDMA device so don’t waste your money asking for unlock codes from these firms.

If you have a GSM device, unlocking is relatively easy and will most likely allow you to use your current carrier’s network services. Before you pay for an unlock code, be sure to contact your network operator to ask if your phone is compatible. Remember, getting an unlock code will not magically remove restrictions on your phone or make it compatible. Working closely with your carrier is necessary so you get accurate, first hand information.

Problem #2: How to fix a Galaxy S9 that randomly reboots after installing an update

I just got a Samsung s9 and when I connected to wifi it updated the software. Now it’s turning off and on and when i try to do a hard reset it gives me this message “security error: this phone has been flashed with unauthorized software & is locked. Call your mobile operator for additional support. Please note that repair/ return for this issue may have additional cost. ” the phone was bnib this afternoon, is there anything I can do?

Solution: Is this a brandnew Galaxy S9? If it is, don’t waste your time by fixing the issue on your own. We suggest that you demand for a replacement to save you from hassles.

If the device is pre-owned or previously used, we can’t think of a reason why an OTA (over-the-air) update will lead to this situation. We assume of course that you update the device normally and not via Odin. If the error occured after an OTA update from your carrier, make sure to contact them so they can create a ticket about the issue.

In some rare cases, normal updates may lead to boot loop or random shut downs. If you did not tamper with the software in any way and the only different thing done was to install an OTA update, factory reset may help. Try booting the device to Recovery Mode and factory reset it. Here’s how:

  1. Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

If factory reset will help, work with your mobile operator to figure out what went wrong with their new firmware update.

Problem #3: Galaxy S9 can’t make a call or call keeps dropping

I have recently purchased a dual sim from Kogan Australia and moved from Virgin mobile (which no longer operates in Australia) to optus (Virgin used the optus network so I thought there would be no issues). I previously had a samsung s7, great phone. I am in a capital city however now when I am in my car either through bluetooth or when the car is stopped I cannot make a call or it drops out, hangs like its trying to connect and over 5  km, will ring and then nothing or doesn’t connect at all. It’ the same when I receive a call I go to answer and it just hangs and doesn’t connect. Also I use the Waze app (Navigation) which also worked great on the Samsung S7, it keeps dropping out in the location etc. I have called Samsung 3 times and Optus twice, they say see the supplier Kogan?

Solution: The reason why Samsung or your carrier refers you to the retailer is to get a replacement, which is a more efficient option to resolve the issue than do some basic, unguaranteed troubleshooting. There’s no direct way to know why your S9 works this way so Samsung or your carrier wants to save your time and effort by getting the device replaced right away. Before you do that though, we suggest that you try two simple troubleshooting — reset network settings and factory reset.

How to reset your S9 network settings:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap General Management > Reset settings.
  3. Tap Reset network settings.
  4. If you have set up a PIN, enter it.
  5. Tap Reset settings. Once complete a confirmation window will appear.

How to factory reset your Galaxy S9

Refer to the steps above.

If both troubleshooting steps won’t make any difference, go ahead and get the phone replaced.

Problem #4: Galaxy S9 won’t detect SD card

My Galaxy S9 suddenly will not recognize my SD card at all. It did this once a few months ago when it got too hot and all I did was turn off the phone to cool it down for about an hour then turned it back on and my card was again recognized. This time out of the blue it happened when my phone had not been used in a few hours and was recently charged. It is in a case so I am pretty sure no dirt got in where the card is located. Please help! Not sure of Android version.

Solution: There are two general reasons for this problem — either it’s an issue with your SD card, or there’s a bug in your phone. To know which one is easy. Here’s what you need to do:

  1. Reformat your SD card using your S9,
  2. Restart your S9 and check for the problem.
  3. If everything works normally, then you’re probably good to go.
  4. If your S9 can’t read the SD card after it’s been reformatted, get another SD card. This will help you tell if the issue is phone-related or not.
  5. If your S9 detects the second SD card and can use it normally, then the first SD card must be defective. Otherwise, you should have a phone issue.
  6. If you think it’s a phone issue, do a factory reset and see what happens. Factory reset should clear the software of bugs.

How to fix Galaxy S9 random restart: works for minutes before restarting on its own

Hello and welcome to another #GalaxyS9 troubleshooting article for the day. In this short post, we bring you another classic case of random restart issue. As usual, we also provide the solutions you can try on your end to fix it. Just remember, random restart issue has a hardware side as well. If all software solutions fail, you can assume bad hardware is causing the trouble.

Before we proceed, we want to remind you that if you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page. When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start.

Today’s Problem: How to fix Galaxy S9 random restart: works for minutes before restarting on its own

Hello. my Samsung S9 keeps glitching… after it dies my Samsung turns on and then when I try using it it wont let me. It would turn on and then a couple minutes goes by and then goes off again. It’ll do this for more than an hour and then work like nothing happened. Is it possible a drink could’ve gotten into it and it f’ed it up??

Solution: The Galaxy S9 is a water-resistant device so it can’t be damaged by casual liquid or water splashes. The water-resistance protection in your device though can be compromised if there’s a physical break in the phone, like after dropping it, or if there’s a factory defect without you knowing it. Galaxy S9 devices with defective water resistance from factory is very rare and does not always result to problems unless a user swims or dives with the device. If you happen to dampen the device with liquid or drink before, all you have to do is to simply rinse it thoroughly with tap water to remove any residue. Once you dry the device properly, you can use it without any issues. So, we don’t think the reason for your main problem is due to water or liquid damage at all but probably a software or a deeper hardware malfunction.

To troubleshoot the device, follow our suggestions below.

Use another charging accessories

The first step is to ensure that the battery is charged properly. If it does not get the right amount of power before you turn the phone on, or if there’s an external issue charging wise, it may not work properly whenever it’s stressed by normal use. To see if there’s any issue with the current charging cable and adapter, try charging your phone with another set of accessories. If you can’t readily find an official S9 charging cable and adapter, you can do these things:

  • borrow them from a friend
  • use ones from your local Samsung store
  • use a wireless charger

Remember, your goal here is to check for the possibility of a charging cable or adapter issue. If nothing changes after doing any of the suggestions above, proceed to the rest of steps below.

Clear cache partition

If you can manage it, the next step that you want to do is to boot the phone to Recovery Mode and wipe its cache partition. This is one of the partitions in your phone’s storage device that keeps the system cache. Sometimes, updates and app installations cause this cache to get corrupted, in turn, causing all sorts of problems. To see if you have a cache problem, follow the steps below to clear the cache partition:

Turn off the device. This is important. If you can’t turn it off, you’ll never be able to boot to Recovery Mode. If you are not able to shut the device off regularly via the Power button, wait until the phone’s battery is drained. Then, charge the phone for 30 minutes before booting to Recovery Mode.

  1. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  2. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  3. Press the Volume down key to highlight “wipe cache partition.”
  4. Press the Power key to select.
  5. Press the Volume down key to highlight “yes” and press the Power key to select.
  6. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  7. Press the Power key to restart the device.

Re-calibrate battery

Should nothing change after the system cache has been refreshed, the next step in your troubleshooting ladder is to recalibrate Android and the battery. Sometimes, Android may get inaccurate battery readings if the device is left running for a long time. It’s advised to regularly calibrate the battery to avoid having power problems.

  1. Drain the battery completely. This means using your device until it powers down by its own and the battery level reads 0%.
  2. Charge the phone until it reaches 100%. Be sure to use original charging equipment for your device and let it charge up completely. Do not unplug your device for at least two more hours and also don’t use it while charging.
  3. After the elapsed time, unplug your device.
  4. Restart the device.
  5. Use your phone until it completely runs out of power again.
  6. Repeat steps 1-5.

Observe in safe mode

One of the possible reasons for your problem may be an inefficient app, or even app-based malware. This is also one of the common reasons for a lot of Android issues. To check, restart the phone to safe mode and observe. If your S9 works normally and won’t reboot on its own, then one of your apps must be to blame.

Here are the steps on how to boot to safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen.
  3. When “SAMSUNG” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.
  8. Observe the phone while it’s on safe mode for at least 24 hours.

If the issue won’t happen when your S9 is on safe mode, bad third party app is behind it.To identify which of your apps is causing the trouble, you should boot the phone back to safe mode and follow these steps:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your S9 is still problematic, repeat steps 1-4.

Factory reset

In majority of cases similar to yours, factory reset is the ultimate test to see if the cause is a software bug or not. It’s also the one way to know whether the issue is fixable on an end user’s level. Needless to say, you want to factory reset your S9 should all our suggestions above won’t help.

Factory reset wipes all user data so be sure to back your files up before doing it. We assume you create a copy of your irreplaceable data regularly but if you haven’t, try to back them up to a computer instead of uploading them to a cloud. Not only is a backup to a computer faster but it can also ensure that your S9 is being charged while it’s moving files. For a more efficient backup job, try to use Samsung’s own Smart Switch.

To factory reset your S9:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

Get professional help

As an end user, there’s only so much that you can do to troubleshoot this issue. If your phone continues to show the same problem after a factory reset, this means the problem is probably deeper. It can be a bad battery or any other logic board issue. To know where the problem lies, a technician must conduct a full hardware diagnostics. Only then can Samsung advise you whether or not the phone can be repaired or if it needs replacement.

How to fix a Galaxy S9 that keeps restarting and asking for PIN

Hello and welcome to another troubleshooting article. This time, we would like to bring to your attention three issues for the #GalaxyS9. As usual, we took the liberty of posting the issues sent our way by some members of our community. We hope you’ll find our suggestions helpful.

Before we proceed, we want to remind you that if you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page. When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Problem #1: How to fix a Galaxy S9 that keeps restarting and asking for PIN

I have a Galaxy S9 which sometimes keeps stuck in a reboot loop or asks for the PIN code because it says its been rebooted while its not. I had to apply factory resetting 3 times already which cleans all software to factory resetting. This is because it was the only solution to get my phone working again. Soft rebooting or cache cleaning didn’t work. I only use a few apps that are widely used, because of my fear of a corrupt software in one of the apps. Sometimes my phone works fine for a week or so and then for no reason it falls back in the rebooting loop. I wonder if it could be a hardware problem, but the strange thing is that the phone works normally for a week and then suddenly falls back in the reboot loop. One time this occured while warching a video, but also it occured 2 times while I was not using the phone. I hope you can have some support on this issue. Thank you very much.

Solution: For this type of issue, you need to narrow down the possible factors. There’s no direct way to identify the reason for your problem by simply telling us the behavior of your device.

Check for bad third party apps

Bad app can be one of the reasons for this problem so the next best thing to do is to restart your phone to safe mode. With your phone in safe mode, all third party apps, those that you added, will be suspended. If your device works normally and won’t reboot in safe mode, our suspicion must be correct.

To boot your S9 to safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen.
  3. When “SAMSUNG” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.
  8. Observe the phone for at least 48 hours to notice any difference. Do not restart the phone during this period.

Remember, safe mode is just a utility tool but it won’t identify the problematic app. If your S9 works fine on safe mode only, you can bet there’s a bad third party app behind it. To identify which of your apps is causing the trouble, you should boot the phone back to safe mode and do the process of elimination.

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your S9 is still problematic, repeat steps 1-4.

Alternatively, you can also do the opposite by wiping the phone again (factory reset), and checking what happens after installing an individual app. Make sure to set aside long enough time to observe the phone after adding one particular app.

Stick to official apps only

Another way to keep bad apps from causing issues is to be stringent when it comes to your choices. If you are adventurous when it comes to apps and does not screen what stuff you add to your device, it’s only a matter of time before you’ll encounter problems. Apps, like Android, can sometimes be poorly coded. If you happen to add an inefficiently coded app, it may be trying to interfere with the operating system at all times causing the system to crash. Apps in your phone are your responsibility so there’s really no one else to blame but you if you encounter problems from one of them. Make sure that you check reviews by other users so you’ll know if there are other people experiencing problems.

Avoid installing apps from unknown or untrusted source. If you are fond of getting apps outside the Play Store, make sure that it’s compatible with your operating system.

Return software to stock

If your S9 is rooted, running a custom ROM or any unofficial software, try to restore everything back to stock (official Samsung software). Once you’ve done that, let your phone run for at least a day and see how it works. If the random reboot issue won’t occur, the software you’re using must be incompatible or buggy.

To minimize problems, try to use official software only. Custom ROMs are less stable compared to official ones.

Hardware malfunction

Your Galaxy S9 is a sophisticated gadget which requires good working software and hardware. In your case, the problem is most probably being caused by a software or app or something that you add later on after a factory reset. To help yourself narrow down the causes, be mindful of what you do with your phone after a factory reset. For instance, if the phone starts to reboot only after a particular app is back in the system, that may be the reason for the problem. Undo your recent change and see what happens.

If all the software tweaks above won’t help though, you can assume that the problem may not be fixable at your level. In this case, you want to get help from Samsung. It’s for them to decide whether or not they’ll repair or replace it.

Problem #2: What to do if your Galaxy S9 stopped charging after it got wet

I spilled a cup of liquid on the dining table. The phone was plugged up to the wall charger; SOME water went on the bottom of the phone where the wall charger connected. I dried off the phone and it worked o.k. I also dried off the cord connection to the phone and thought everything was alright. The next morning the phone would not charge. So I left it another day. Then the phone read “charging” and it did so. But the next time I tried to charge, the battery with the lightning bolt came up, then changed to the yellow triangle with an exclamation mark. I have since tried charging it a couple times, but it either does NOT show the charging icon, OR (once or twice,) the yellow triangle and exclamation mark came on for a few seconds then went off.

Solution: The Galaxy S9 has water-resistance protection and will automatically stop charging if it detects water or moisture in the charging port area. A moisture detected warning or error will also warn you in such a case. What you have to do is to dry the charging port thoroughly and leave the phone for a few hours. Once you’ve done that, charge it again.

If the phone still refuses to charge at this juncture, you should consider using a different set of charging accessories. If possible, use an official Samsung charging cable and adapter for the S9. Try to borrow one from a friend or from your local Samsung store.

If your phone still refuses to charge, wipe its software and return everything back to stock by doing a factory reset. Here’s how:

  1. Create a backup of your data.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

If nothing changes following a factory reset, the problem must be hardware-related. There may be an issue with the charging port or it may be damaged. You should contact Samsung so they can set up a repair appointment for you.

If you don’t want to send the phone to Samsung right away, you can try using its wireless capability in the meantime. Wireless charging is slower than regular cable charging so do it sparingly.

Problem #3: Galaxy S9 keeps getting ad popups after an update

After the following update, my camera and messaging apps were corrupted and I had to reinstall. After rebooting and restarting, I find that I am bombarded with ads. When opening my phone I must delete 4 or 5 ads just to get to my homepage. Ads are popping up at any time regardless of where I’m at throwing me out of text conversations and off Facebook back to my homepage. I have never experienced this issue before and don’t know what’s causing it or how to fix it. Not sure I can remove the update. Update: G965USQS3ARG8 Applied August 23, 2018 10:06 am.

Solution: Android updates don’t bring ad pop ups. The most likely reason is a bad app that you installed. Wipe your phone with factory reset (refer to steps above) and then make sure that you screen what apps to add back. Avoid re-introducing apps you don’t recognize or those from suspect publishers. Keep in mind that app building is a expensive. If not a lot of people install apps, or if a product does not make enough money, its developer may opt to use less legit means, like hijacking a device and forcing it to display ads all the time. The more ads are shown, the more revenue it is for the developer.

Some malicious apps may appear legit initially but will hen change to something sinister later on. Some may allow a hacker to harvest personal information or lets other apps to be installed in the system without your permission. Such apps will then take over the system and bombard it with ads. Some of these malicious apps may come in the form of games, personalization apps, or anything under the sun.

Antivirus app

While some free antivirus apps may warn you and prevent some forms of malicious apps and codes, there’s only so much that they can do. You have to be vigilant and not rely on automated systems to protect you and your personal information. Only add apps from trusted sources. Do not install apps unless you absolutely need them.

If the problem continues after you’ve successfully factory reset the device, that means you are not careful enough with your apps. Do another system wipe and this time, be very selective with your apps. We can’t emphasize this enough but you are your phone’s first line of defense. Blame yourself if the issue returns.

S9 Randomly Restarts

Problem: Hi, I went through your and other troubleshooting guides but with no luck. I am working with the S9 and the OS is up to date – not sure which android version I’m running. I thought I was having issues with an app. so over the past week I’ve done factory resets and not loaded any content onto the phone. It worked great until I would use my google log in where everything was backed up and the “bad apps” would cause the phone to restart randomly, in the middle of phone calls, while texting, or just sitting on the desk. I would factory reset and same things would happen. I finally reset and brought nothing over and used a new google acct to back up. After a few days it would start to do the same thing – randomly shut down/restart. It always booted up but sometimes would take 1 minute sometimes close to 5 minutes. Apps, email, texting, contacts could work as usual or take up to 30 seconds to open and react. This morning I was going through contacts and it was slow – major lag and then shut down. I figured it would restart as it always did in the past but when I check a couple hours later it did not restart. That was when I started to troubleshoot it. Nothing on the list helped including random “it really works” stuff on the internet – put in freezer and try booting when cold. The only sign of life from the phone was when plugging into the computer I would get an external device attached notification but the computer would not read the device (normally the device name and today I got nothing). The battery was at about 90% when it restarted. I’ve tried different chargers, different usb cables, soft reset, hard reset,, etc and nothing works. Any advice on what might work that I have not tried yet? Do I just need to pull the trigger and get a new phone? Thank you

Solution: Since you have already performed most of the troubleshooting steps recommended for this particular issue then this is most likely caused by a faulty hardware component already. The best thing you can do right now is to bring the phone to a service center and have it checked.

S9 Randomly Reboots

Problem: S9 rebooting non stop. if the phone cuts on, i can’t attach my charger or it will turn off and reboot again. i can only use my charger if the phone is off, and the phone only turns on if the battery is above 70%. then i got a notification saying my samsung account has expired. now i cant use mobile network, it says that i have to insert sim to use mobile network. my sim worked when using someones device.so i got replacement sim and it still didn’t read. also my phone battery overheats. can you hep

Solution: The best thing that you can do right now is to backup your phone data then do a factory reset. Make sure to remove the microSD card when you do the reset. Once the reset is complete do not install any apps in your phone. Try to check first if the issue still occurs. If it does then this is most likely a hardware related problem already in which case you will need to bring the phone to a service center and have it checked.

S9 Heats Up

Problem: I just bought Samsung galaxy S9. if i turn on flight mode, it will cool down. but as soon as i turn off the flight mode, it will heat up. by the way, my mobile data is always on though i don’t use my phone but just keeping aside and no activity on the internet. my sim is in a roaming. any help would be thankful

Solution: If you are in an area with a weak mobile signal reception then your phone will have the tendency to heat up as it uses more power to get a good reception. To check if this problem is caused by a weak signal try removing your phone SIM card then make sure that flight mode is off. If the phone does not heat up then you will have to be in an area with a good reception to fix the problem.

If the issue persists even with the SIM card removed then I suggest you backup your phone data then do a factory reset. Once the reset is complete try to check if the issue still occurs.

If the above steps fails to fix the problem then you will have to bring the phone to a service center and have it checked.
