Galaxy S2 Gets Stuck on Samsung Sign

Problem: Hi, I’ve been using my Samsung Galaxy S2 for over a year. It’s been used for almost two years and half by my father. Recently I had a problem. I plugged my S2 into the charger over night and woke up with the S2 stuck on the Samsung loading sign (startup). There was time were the motherboard of the phone fried up during my father’s time and he had to replace it for a $100 because nothing would turn on. I’m fairly certain it’s not the motherboard this time but something that has to do with the startup. Every time I take out the battery, and re-insert it, it loads and gets stuck on the Samsung sign. Please help. — Cali

Troubleshooting: No, it’s not the motherboard, it’s not even a hardware issue. If you just plugged the phone to charge and this problem happened, then it must be just a minor glitch that can be solved by either soft reset or wiping the cache partition.

Soft Reset

For minor hardware and software glitches, soft reset is very effective that is why it is recommended you follow the procedure below if the phone cannot boot up properly.

  1. While the phone is on, remove the back cover and pull the battery out.
  2. Press and hold the Power key for a minute.
  3. Place the battery back in and the back cover.
  4. Turn the phone on.

Wipe Cache Partition

Just in case soft reset can’t fix the problem, then try wiping the cache partition. It is often very effective is fixing issues like this. Just follow the steps below:

  1. Turn off the device.
  2. Press and hold both Volume Up and Volume Down keys at the same time.
  3. Press the Power key only until the phone vibrates once, then release only the Power key.
  4. Continue to hold the Volume up and Volume Down keys until the Android System Recovery screen appears.
  5. Press the Volume Down key to highlight wipe cache partition.
  6. Press the Power button to select.
  7. Highlight reboot system now and press the power button again to reboot.

Galaxy S2 Will Not Power On

Problem: Hey there, I owned my Galaxy S2 India version for 3 years. One day after playing a video it struck for a while and went dead. From then, phone is not booting. Plugging in charger also not showing battery indicator, but leaving charger for a while heats the phone warmly near the camera part. I tried hard booting but in vain.

Then I took the phone to authorised service centre. They charged me 100/- rupees and told that motherboard needs to be replaced. They also told that new motherboard will cost 6000/- rupees. So I’m in a fix to purchase new mobile or to go with repairing. Kindly provide me your expert device. What happened with my device? And can it be repaired in less cost? Regards, Srinivas.

Suggestion: If the techs were absolutely sure the problem was with the motherboard, then I suggest you buy a new one probably the later models. Buying a new motherboard and paying the tech to replace the busted one may still be a little cheaper than buying a new phone. But it’s a “repair” process! Meaning, there is still a possibility the device won’t work after that. If that happens, then expect your fees to go a little higher not to mention the inconvenience you will experience.

It is crucial that the tech would properly diagnose the problem because there is a big chance that the problem isn’t the motherboard but the daughterboard where the USB Charge port is attached. This component should be properly diagnosed because according to you, the phone heats up when plugged in to charge. But then again, if you don’t want to go through all the hassle, just buy a new phone.

Galaxy S2 Won’t Boot with New Battery

Problem: Hi! I’m having an issue with my phone! The Galaxy S2 wasn’t turning on and wouldn’t even charge so I recently got a new battery to it and its still doing the same thing, but this time it charges but when I turn it on it won’t stay on and simply goes back to the battery charging screen plz help really want to use my phone. Thanx! — Richard

Troubleshooting: At least, the phone will now charge, that’s a relief. I think it’s a minor hardware glitch. Try to charge up the battery until it’s full. Once finished, remove it from the phone. Now, press and hold the Power key for a minute. After that, place the battery back in and attempt to turn the phone on. If it still refuses to come back on, try booting it in safe mode:

  1. Either the phone is on or off, remove its battery just to make sure it’s completely turned off.
  2. Re-insert the battery.
  3. Press and hold the Power button.
  4. When you see the first logo, release the Power key but immediately press and hold the Volume Down key.
  5. Continue holding the Vol Down key until the device has finished rebooting.
  6. When it reaches the Home or Lock screen, you will see “Safe mode” at the lower-left corner.

If the phone won’t boot up in safe mode, try booting it recovery mode:

  1. Turn your phone off.
  2. With the phone off, press and hold the Volume Up key and the Home key, then press and hold the Power key. You’ll see the Android recovery screen.

The purpose of these procedures is for us to know if the phone can still boot up in any mode. If not, then it’s probably a hardware issue. But in case the phone can boot up in recovery mode, try wiping the cache partition first and if that failed, proceed with master reset.

Galaxy S2 While Using Random Apps

Problem: Sir I have Samsung Galaxy S2 T-Mobile with 4.1.2 os when I take photo from camera with flash my phone get restart not only with camera when I run sound cloud and some other apps my phone restarts I have tried many ways like reinstalling apps and resetting phone. Sir, help me.

Troubleshooting: I believe it’s not just a camera problem. In fact, there’s a possibility that it is a firmware issue. But before anything else, let’s try to isolate the problem by booting the phone in safe mode:

  1. Remove the battery from the phone.
  2. Re-insert the battery.
  3. Press and hold the Menu key.
  4. While holding the Menu key, turn on the device.
  5. When you see the lock screen, you can release the Menu key.
  6. ‘Safe mode’ displays in the lower-left corner.

While in safe mode, try to open the camera and any other apps that you were having problems with. Observe closely if they would still trigger the restart. If so, then our suspicion that it’s a firmware issue is confirmed, otherwise, some of the apps you installed are causing the problem. But either way, it is best if you reset the phone and give it a fresh start. Try backing up your data first and proceed with full hard reset via recovery mode:

  1. Turn your phone off.
  2. With the phone off, press and hold the Volume Up key and the Home key, then press and hold the Power key. You’ll see the Android recovery screen.
  3. Scroll to Wipe Data/Factory Reset using the Volume Up or Down keys. Select with the power key.
  4. Scroll down to Yes, Delete User Data and select it.
  5. Your master reset is now complete.
  6. Go to Reboot System Now to restart the phone.

Galaxy S2 Stuck on Factory Mode

Problem: After updating my Samsung S2x to the latest firmware with issuing kies air I have black writing on my home screen. Basically it’s the phone information written on my screen and this won’t go away. I did call tells and did a factory reset and the writing is still there. I haven’t seen anything written about this issues. Let me know if there is something I can do. Thanks. — Melanie

Troubleshooting: When the phone is stuck in the factory mode, the problem is more complicated than it seems but I know a couple of users who experienced this problem and successfully resolved it by following the simple steps below:

  1. Pull the battery out of the phone.
  2. Press and hold the power key for one minute.
  3. If the battery has been depleted, insert it and power on the phone. The battery icon will appear showing an icon of a battery without current left and the phone will shut down.
  4. Plug the phone to charge and attempt to turn it on.
  5. There’s a chance the phone will boot up normally after this.

However, if the problem persists after doing these steps, then let the tech “re-flash” its firmware. That should do it.

Galaxy S2 Won’t Charge

Problem: Hi! My Samsung Galaxy S2 will charge when plugged into my computer but not through the wall charger. I have tried a new charger and USB cable but the same thing happens. What is the problem do you think? Thanks for any help you can give me.

Troubleshooting: That’s weird! Honestly, I haven’t encountered this sort of problem before. I am, however, assuming you were using the original charger because if not, then that could be the issue. I am also assuming you are using the same USB cable.

I am also curious to know how the phone behaves if plugged in to the travel charger. I understand it won’t charge but is it showing an icon on the screen? I encountered a lot of cases that the charging icon is displayed on the screen but the phone can’t take the charge. There was also one instance when the phone was taking the charge just fine but the phone didn’t show the usual charging icon.

I will have to dig into this issue a little deeper and I sure will get back to you as soon as I can gather more information as to the resolution of this problem.

Galaxy S2 Has Multiple Issues

Problem: Hi there, I’ve had my Samsung Galaxy S2 for a while now and it worked great up until a few months ago. I haven’t updated it or changed anything apart from downloading a few games. To begin with it would randomly open the voice command, i don’t always even have to touch the home button for this to happen. It then started freezing randomly while i was using apps like Facebook which had previously been fine to run. On top of all of this my phone over heats while not even in use and restarts completely on its own. The battery doesn’t hold that well anymore either and its started opening up a clock home screen which i had never seen before until today. On average it opens this every 5 seconds. I hope you can help out. Thank you. — Erin

Troubleshooting: Voice command opens randomly, apps freezing, battery draining fast. Sounds like a lot of problems to me. I know these issues are all connected but we can’t pinpoint what’s causing them. The best way to address them all at once is to perform master reset. But before you do that, backup all your important data first then follow these steps:

  1. Turn your phone off.
  2. With the phone off, press and hold the Volume Up key and the Home key, then press and hold the Power key. You’ll see the Android recovery screen.
  3. Scroll to Wipe Data/Factory Reset using the Volume Up or Down keys. Select with the power key.
  4. Scroll down to Yes, Delete User Data and select it.
  5. Your master reset is now complete.
  6. Go to Reboot System Now to restart the phone.

Galaxy S2 Screen Stays Black, Other Functions Working

Problem: My screen is black but the phone turns on and receives calls and texts. What can I do to get the screen to turn on again? Do I have to replace the screen? Or the lcd?

Troubleshooting: Actually, you’re the only one you could answer your questions. We can’t speculate on things especially if there is not enough information. If this problem occurred due to liquid and/or physical damage, then the problem is more complicated than just a busted display. If the screen has a crack or shattered, then you probably have to replace it. The LCD and the digitizer are glued together, so you’ll have to replace both, although you can buy them as one component.

Galaxy S2 Drains Battery Quicker

Problem: Hi there I have bought a Samsung S2 a few days a ago from a shop near by the battery drains fast can’t do much on the phone i have got a new battery today replacing the old 1   from the same shop where i bought the phone from still no difference the battery has 1650mah do i need a better mah battery help please.

Suggestion: Okay, so you bought the phone just a few days ago and you noticed the battery was draining quickly, what made you think it was the battery? I am pretty sure you don’t want to use a defective phone for years, right? You know, you’re still inside the period where you have all the right to be meticulous about the phone you will use for a few years, so I suggest you get the phone replaced. Sorry, I just can’t see the point of troubleshooting a brand new phone because ideally, a new phone should work perfectly. That is why, it is recommended you got the phone tested before signing the invoice.

Galaxy S2 Won’t Boot Up Normally

Problem: Hi, I recently had a new sim reader put in my phone. I’ve had this phone for just over 2 years. I had problems with charging it for a while so i purchased an external charger which has been fine. However this morning, i put in the fully charged battery and on arrival at work my phone had switched off. I switched it back on again and it wont open up properly following the Samsung icons and keeps going round in circles. I have rebooted a couple of times..taken the battery and sim out and re-inserted but still does the same. I have just spoken to a guy in a mobile phone repair shop and he seems to think i may have lost my data as it doesn’t seem to be able to find it. Please can you help? — Sharon

Troubleshooting: Why did the tech said you may have lost your data? Did he reset your phone? You know, for problems like this that occurred without apparent reason, they’re more likely a glitch in the firmware or hardware. In that case, wiping the cache partition will fix them, although, I’m not really sure about your case especially if the tech already did some things that may have make things worse. To try to wipe the cache partition, follow these steps:

  1. Turn off the device.
  2. Press and hold both Volume Up and Volume Down keys at the same time.
  3. Press the Power key only until the phone vibrates once, then release only the Power key.
  4. Continue to hold the Volume up and Volume Down keys until the Android System Recovery screen appears.
  5. Press the Volume Down key to highlight wipe cache partition.
  6. Press the Power button to select.
  7. Highlight reboot system now and press the power button again to reboot.

Galaxy S2 Vibrates and Turns On Randomly

Problem: Hello. Sorry to bother you. I’m having a problem with my Samsung Galaxy S2 from T-Mobile. It vibrates and turns on randomly. While it vibrates, sometimes it also makes a funny noise and the camera light flashes. When I try to turn it on, it will start the process of power it on then it stops and starts vibrating with a black screen. I cannot charge my phone neither but anytime I press on the Power button it activates the phone. Thanks for helping me in this matter.

Troubleshooting. If this problem happened after the phone got wet, then remove the battery and place the phone in a bowl of rice for a couple of days just to make sure there are no remnants of liquid inside. Based on the symptoms you provided, it could also be that the Power switch is defective or gets stuck from time to time. The vibrating and the refusal to turn on sometimes are among the signs of defective or stuck power switch. If this was the case, you will need help from a technician.

Galaxy S2 Not Picking Up Charge

Problem: Hi there! Hope you are fine, I’m using Samsung Galaxy S2 GT-I9100 running on 4.0 Ice Cream Sandwich. I’m facing a kinda weird problem, I usually charge my phone with original charger and cable but it cannot pick or show connectivity if i connect any other charger or a cable (even its original, now I’m bound to charge with one charger). Since I’m facing another problem with its cable I’m unable to charge my phone.

Secondly when my cellphone’s battery gets low under 40% it start draining battery so fast that it consume 5% per seconds & some time screen starts to flicker & phone turns off itself… I’ve changed batteries about 3 time but still exist. Awaiting for your reply. Best Regards, Shaikh.

Troubleshooting: I’m a bit confused with your message, Shaikh. You said the phone charges fine when you use the original charger and cable but it won’t when using other charger or cable. I don’t see a problem in that; if “other” charger and cable won’t work, why use them? You have the original ones! Just to make things a little clearer, “original” to me means the charger and cable that came with the phone. Other chargers and cables, even if they’re from Samsung, are considered third-party.

Now, about the other problem, I think you need to have the phone checked by a technician because even the “fast draining” issues I’ve encountered cannot beat the 5% per second battery depletion rate. There must be something wrong with the hardware.

Galaxy S2 Enter Key Not Working

Problem: Hi. I have a problem regarding my Samsung Galaxy s2 NTT docomo. My problem is that the enter key doesn’t work. i tried different keyboard apps and configuring the settings (language and input) but it still doesn’t work. i really hope you can help me with this. thank you so much.

Troubleshooting: Try to check if the Enter key won’t work in both portrait and landscape modes. If it works in one of the modes, then it’s a screen problem and the digitizer may need replacement. On the one hand, if the Enter key won’t work in both modes, then it’s an app or firmware issue. Clear the cache and data of Samsung keyboard through app manager first. If that won’t work, proceed with factory reset.

Galaxy S2 Gallery App Disappeared

Problem: Out of nowhere my photo gallery app has disappeared. Widget used when driving with talk an another feature has disappeared also. Please give info to fix the issue. I am using a Samsung Galaxy S2 with 4.1.2.

Thank you, Patricia.

Troubleshooting: Hi Patricia. I am sure factory reset will fix the issue for you. I don’t want to ask why the stock app just disappeared together with some features but in order to bring them back, you also need to bring the phone to its factory settings:

  1. From the Home screen, tap the Apps icon.
  2. Scroll to the right and touch Settings.
  3. Scroll down and tap Back up and reset.
  4. Select Factory data reset.
  5. Choose Reset device, and touch Delete all button.
  6. Once all data and settings have been deleted, the phone will automatically reboot.

Galaxy S2 WiFi Won’t Turn On

Problem: Have looked at and tried your suggested remedy 33-6 to no avail. The phone has not been dropped or otherwise injured. The wifi switch simply quit working. When switched to ‘On’ the slide immediately returns to off. Available networks are not shown. Other options under ‘wifi’ are not shown. Modem/router is fine as another cellphone has no problem connecting. Unlocked (was tied to AT&T) phone and upgraded to Android 4.1.2 several months ago; no problem there. This problem occurred once for a few days several weeks ago but then suddenly went away on its own. It started again three days ago. Suggestions? Thanks for any help. — Mike

Troubleshooting: Hey Mike. I’ve seen this kind of issue many times and booting in safe mode and turning the WiFi switch on and off often works. If not, then wiping the cache partition so that the phone will be forced to create new caches for the WiFi service will fix it. If that won’t work either, then perform the full hard reset. This is the last resort and it works all the time. However, if it also failed, then there’s an issue with the chip that handles wireless connectivity. You need a technician to fix it.

Galaxy S2 Turns On and Off By Itself

Problem: Hello, I have a Galaxy S2 that I bought a year ago. I have an issue with it where it doesn’t turn on; basically it’s power-cycling. When I push the power button to turn it on, it appears as if it’s about to come one then it goes off again. It will go to the Samsung/t-mobile logo then it shuts off. And it does that over and over again. I was wondering if you guys can fix it or retrieve all of my notes and pictures from it. Thank you! — James

Troubleshooting: Hey James. The power button in your phone is stuck or may be damaged that’s why it’s doing that. All you can do is attempt to get the button out of being stuck and if that won’t work, then you really need a technician to figure it out for you. If the button was damaged, it will be replaced for a small fee.

Galaxy S2 Won’t Turn On With New Battery

Problem: I have an AT&T Samsung S2 which was working fine until I left the battery go dead for a couple of weeks. I have now tried multiple times and chargers to recharge the battery and it will not recharge. I have purchased a new battery and it still will not turn on. What can I do and is there any way to factory reset it without it turning on? Thanks.

Troubleshooting: No, you can’t reset the phone if it’s turned off. There is a couple of procedures you can try to know if the phone can still boot up: safe mode and recovery mode. If the phone failed to boot in either of these modes, then it’s more likely a hardware issue, send the phone in for repair.
