Problem #1: Galaxy S7 keeps showing “Contacts has stopped” error

Hi. I appreciate the fact there is someone out there willing to help with this nonsense. I am dealing with the “Contacts has stopped” issue. I’m not sure what’s causing it. It’s now happened for a 3rd time and what i did to correct it in the past no longer works. I did the “clear cache” as well as hold the Volume and Home key down then power on to clear cache partition. I’ve done it several times. I will not clear data since it tells me i will lose all files. I only had the phone for one week the first time it happened. I’ve now owned it for about 7 weeks and i have no idea what’s causing it. I have updated the phone a few times. I am thoroughly disgusted with Samsung for not creating a patch for this problem. I will not be purchasing another one in the future. I am at a loss and have no idea what to do. I cannot use the phone to call out. I’m to the point of getting my credit card involved to get my money back and start over. I’m not tech savvy. If you can help, great. Thank you. — John

Solution: Hi John. Since you’re dealing with one particular app here, we strongly recommend that you do all the basic software troubleshooting if you want to get to the bottom of this issue. If you don’t want to lose important files and contacts, mke sure to back them via Smart Switch first. This is a free application from Samsung designed to give users like you an easy option to create copies of their important files to another device. Smart Switch can be installed on another Samsung smartphone that you can use to keep your files but we recommend that you use a computer instead. If you haven’t tried using Smart Switch yet, we recommend that you visit this link for step by step instructions.

Once you’ve already created a back up for your important data, your next step would be to clear the cache and data of Contacts app. Here’s how:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Data and Clear Cache buttons for the application.

After clearing Contacts’ cache and data, be sure to restart the phone and see if the problem is resolved. If nothing changes, you must do a full wipe by doing a factory reset.

  1. From the Home screen, tap the Apps icon.
  2. Find and tap Settings and then touch Backup and reset.
  3. Tap Factory data reset and touch Reset device.
  4. If you have screen lock feature turned on, enter your password or PIN.
  5. Touch Continue.
  6. Tap Delete all to confirm your action.

Problem #2: Galaxy S7 Settings app keeps crashing after installing Android Nougat

Settings keeps crashing. I’ve tried wiping the cache, starting in safe mode, and a complete factory reset. Still does it. It seems to be limited to the wifi settings. I can’t pull up the available wifi channels. If I long press the wifi icon on the drop down notifications (or if I go deeper into the wifi manager), I get a message that the settings app has crashed. The same happens if I try to setup wifi calling. This all started when I updated to Nougat. — Adam

Solution: HI Adam. If the problem occurred right after installing an Android update and you downloaded it from your carrier (OTA update), the problem is most probably beyond your ability to fix. There’s a chance that the firmware you installed is poorly or inefficiently coded. An issue like this is usually fixed by a patch but it may take some time to arrive, especially if there’s no one or only a small number is reporting the issue. We suggest that you contact your carrier and let them know about it.

If you updated the operating system via others means and not by air, your only way out may be to revert to the previous firmware version by manually flashing it.

Problem #3: Galaxy S7 edge calls keep dropping, getting hot when charging

Hi. I just got my Galaxy S7 edge. I only had it for 2 weeks now. It’s good but i have garbage service. My calls keep dropping, I am having connectivity issues. I can’t take a video, watch a video or go live from Facebook. i am through Straight Talk Smart Pay.

My Galaxy Grand Prime is cheaper and works better. Can you please help me to figure this out?

Of course I’ve factory reset it once already. It’s also starting to burn while chARGING. BASICALLY GETTING TO HOT. — Nene

Solution: Hi Nene. If factory reset did not fix the issues and it gets hot when charging, the phone is most probably having a hardware malfunction. Some of the common causes of bad hardware includes accidentally dropping the device, exposure to elements (cold, heat, water, moisture), and manufacturing defects. If this was a brand new phone and not a pre-owned one when you got it, contact the seller or your carrier so you can have the hardware checked for errors.

For your network service issues such as random voice drops and internet connectivity interruptions, it’s important that you seek the help of your carrier as they can be due to service outages or poor coverage quality in your area.

Problem #4: Galaxy S7 fast charge not working

I have the same issue as concerns of many. i am worried too. My device does not fast charge and is showing cable charging for up to 7 hours charge time. I did clear system cache about 3 times on my device and the matter was not resolved. I have tried different original fast chargers and the charger doesn’t seem to be an issue but perhaps it’s the device. If my phone cable charges instead of activating fast charging does this cause damage to my device? Thank you please reply a.s.a.p. — Ridah

Solution: Hi Ridah. A lot of times, fast charging issues boils down to a faulty charging port but we’ve never heard of it causing other problems in a device. Fast charging feature can sometimes also be caused by a software glitch so if you haven’t tried it yet, we recommend that you do a master reset at this time. If you can’t restore the fast charging feature after this reset, you can assume that bad hardware is to blame. To fix it you should, you can either have the phone repaired or replaced.

For reference, here are the full steps on how to master reset your Galaxy S7:

  1. Create a backup of your important files such as photos, videos, etc.
  2. Turn off your Samsung Galaxy S7.
  3. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  4. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  5. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  6. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  7. Once highlighted, you may press the Power key to select it.
  8. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  9. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  10. The phone will now reboot longer than usual.

Problem #5: Galaxy S7 “Settings has stopped working” error when opening wifi

So I’m getting the “Settings has stopped working” notification whenever i try open my list of available wifi networks and occasionally when i leave the slide down settings bar open. I followed the steps on one of your posts, did the master reset and i could once more use wifi as normal and access the nearby networks. I then restored my old back up and am now back to not being able to access the wifi menu again. Any advice on this issue?

*i can still reconnect to networks automatically i had already connected to before this issue started. Thank you in advance. — Lockie

Solution: Hi Lockie. Looks like your issue is similar to the one Adam is experiencing above. If “Settings has stopped working” error started happening after you installed the most recent Android Nougat iteration, this may be a firmware coding issue, which means that there’s no amount of troubleshooting that you can do on your end to fix it. The only thing that you can do is to report the trouble to your carrier and hope that they can release a patch as soon as possible.

Problem #6: Galaxy S7 cannot save or download MMS

My boyfriend is sending MMS screen shots or multi media messages/pictures. I tap on it to download and it says receiving. Then after a 15-30 seconds it tells me unable to download. Fail. I hope hold my finger on the pic to see what my options are to forward or convert the format and the only option I get is to delete or save attachment. I try to save it and it will either say unable to save to SD card or application not supported or found. I saw on another post when i asked this same question to make sure my phone was set up properly for Metro and the information is all correct. I also have my data turned on and the downloaded another text app that was also suggested called Textra. I don’t see the messages or pics at all on the new app either. What can i do? — Vamj0414

Solution: Hi Vamj0414. If all APN settings are correct on your phone and mobile data connection is working, the problem is most probably account related. This may be the reason why MMS does not also work even when using a third party app like Textra. Contact your carrier and let them fix the issue for you.

Problem #7: Galaxy S7 not receiving all SMS

I have been having a problem with my Galaxy S7 recently wherein people will send me text messages or even phone calls and I simply will not receive them. It seems to be completely random as I will receive a specific person’s message one time and the next time they send me one I will not, but it will appear as sent on their device, and it has happened with many different people. I have not, however, had any problem with people not receiving my messages. For example, my friend sent me an important text message two days ago which I did not receive on my phone. The next day she asked why I never responded and I said because she never sent it to me but upon comparing our messaging apps, (we both use the default messaging apps on our phones) on her iPhone it said the message was sent, but on my phone it was never received. — Tommy

Solution: Hi Tommy. An issue like this can have several moving parts and most of them  can only be addressed by your carrier. The best that you can do on your end is to do some software troubleshooting to hopefully prevent the issue from happening again. In a case like this, identifying the cause is usually almost impossible to do so unless there’s a known network-related glitch already identified by your carrier, there’s really no way of telling for sure where the problem lies. There’s no diagnostics that you can run on your end to help you pinpoint the cause. It can be a device issue or something in your carrier’s system. SMS and MMS issues are best addressed by the network providing them so if you haven’t contacted them yet about it, be sure to do so.

Problem #8: Galaxy S7 is frozen and becomes totally unresponsive

Hi. I have a Samsung Galaxy S7. I live in FL and was outside all day at a vendor event in the heat when the phone got pretty hot and froze up. I did a soft restart (volume down + power) but the screen got stuck in the Samsung screen with the blue led light pulsing. After getting home and letting the phone charge it seemed to be ok. But today it did it again but worse this time. I tried to do a reset to clear the cache but now it is stuck on the Android recovery screen. I am unable to use the volume up or down keys to make a selection as it is completely frozen. What can I do now? — Piphidavis

Solution: Hi Piphidavis. The first thing that you want to do is to let the phone drain battery power, especially if the phone is completely unresponsive. After that, you want to see if you can boot the phone normally or not. If not, that’s the time you will attempt to boot it to alternate modes. Below are the steps on how to do each hardware button combination and a follow up solution for each one:

Boot in Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Should the phone continue to refuse to boot normally, or you won’t be able to boot it to any of the alternate modes above, have it repaired or replaced. The battery may have died or become damaged so it’s good if you can have the hardware checked.

Problem #9: Galaxy S7 turning off on its own while charging

Hi team! Over the last week my Samsung S7 has been turning off while on charge overnight. I use my phone for alarm clock so this has been a little frustrating for the work alarms but hey, happy to get an alarm clock in the mean time. The fault has only happened 3 times within the last week, first and second time the phone was stuck on the Samsung loading screen and I had to force restart. The 3rd time was just turned off while on the battery fully charged screen and turned on with the power button. Each time it does this it closes all apps and when the phone comes back on it will not have alarms set either. I have seen a lot of threads in regards to this but yet to find a solution really? Is there a definite fix for this or what would you guys recommend? I look forward to hearing from you. — Adam C

Solution: Hi Adam C. This may be caused by software glitch so the first thing that you want to do is wipe the cache partition to refresh the system cache. If that won’t fix the problem, you have to do the more drastic solution of factory reset (steps provided above).

For reference, here are the steps on how to wipe the cache partition:

  1. Turn off your Samsung Galaxy S7.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.
