Samsung Galaxy S2 Problems, Questions, Errors and Solutions [Part 23]

Welcome to the 23rd part in our series of troubleshooting articles dedicated to the Samsung Galaxy S2. Now I know most of you might say that this is already an old device however we are still covering this extensively since we still receive a lot of emails from our readers regarding this model. This might be due to the fact that support for this model is now very limited and due to its age several issues are already showing up. In this part, we will be tackling some of the latest issues sent to us by our readers since part 22 was released.

S2 Screen Stays Blank Even If Power Button Is Pressed

Problem: I have a Samsung Galaxy S2 – when the phone is on and the screen is blank, at times (not all the time) I will press the power button to bring up the screen and it stays blank.  But, the control buttons at the bottom of the phone light up then darken.  Press the power again, same result.  Usually it takes from 5-7 times of this cycle to finally bring the screen on.  I have tried restarting it after this happens, no luck.  I have gone into Task Manager, into the RAM section and cleared memory and of course after a little bit, the “closed” programs re-open!  An example – Showing 768 mb of RAM available, 508 mb being used.  I tap clear memory, 21 applications closed and the “used” memory goes down to 405 mb.  After waiting one minute, used memory is back up to 494 mb.  I clear memory again and it says 17 applications closed.  I have Advanced Task Manager on my phone, I go to clear all the unwanted running programs and it does.  Come out of ATM and in less than thirty seconds most are back on.  I have gone into Settings, Applications, clicked on the Running tab and stopped a number of unnecessary Apps.  Looking at it right now, I see some of those I have “stopped” are back!  It is getting to the point I am ready to chuck this phone and get a new one.  Even though I believe it not necessary.

Solution: Before troubleshooting the issue make sure that your phone is running on the latest software update. We all know this is a rather dated device and the chances of an update being released are slim but just try to manually check on it. If there are software updates available then apply them on your device accordingly.

Once you have made sure that your phone is running on the latest software it is time to do the actual troubleshooting process.

The first thing that needs to be done is to clear the RAM of unnecessary data.

  • Turn off phone
  • Take out the battery
  • Press and hold the start button for 3 minutes
  • Reinsert the battery
  • Turn on the phone

What this does is it clears out any unwanted data that may be stuck in the RAM of your phone which may be causing the problem. Try to check if the issue is still present. If it is then proceed to the next step below.

The next thing that needs to be done is to determine if an app or group of apps are causing this problem. To do this you will need to start your phone in Safe Mode. In this mode, only the default apps are loaded while third party apps you downloaded from the Google Play Store are disabled.

  • Remove the battery from the phone.
  • Re-insert the battery.
  • Press and hold the Power key.
  • When you see the logo on the screen, release the Power key. Immediately after releasing the Power key, press and hold the Volume down key.
  • Continue to hold the Volume down key until the device finishes restarting.
  • ‘Safe mode’ displays in the lower-left corner. Release the Volume down key when you see ‘Safe Mode.

If the issue does not occur in this mode then there’s a big possibility that an app is the cause. You will have to use a trial and error method in finding what that app is then uninstall it.

If the issue still persists then your next step is to wipe the cache partition of your phone. This procedure does not delete your data.

  • Turn off the device.
  • Press and hold both Volume Up and Volume Down keys at the same time.
  • Press the Power key only until the phone vibrates once, then release only the Power key.
  • Continue to hold the Volume up and Volume Down keys until the Android System Recovery screen appears.
  • Press the Volume Down key to highlight wipe cache partition.
  • Press the Power key to select.
  • Make sure Reboot System Now is highlighted and press Power key to reboot.

The last troubleshooting step you can perform on the software of your phone is a factory reset. This reverts your phone to its original condition when it was brand new. Take note that your data will be deleted in the process so be sure to make a backup.

  • Turn off the device.
  • Press and hold both Volume Up and Volume Down keys at the same time.
  • Press the Power key only until the phone vibrates once, then release only the Power key.
  • Continue to hold the Volume up and Volume Down keys until the Android System Recovery screen appears.
  • Press the Volume Down key to highlight wipe data / factory reset.
  • Press the Power key to select.
  • Press the Volume Down key to highlight Yes – Delete all user data.
  • Press the Power key to select.
  • Press the Power key to reboot.

S2 Phone Goes Black When Flash Enabled In Taking Photos

Problem: Whenever using the camera if I have flash enabled after taking a photo the phone will go completely black and need to be restarted. What can I do to fix this?

Solution: The first thing that you need to check if this problem is related to a power issue. Try connecting your phone to its wall charger while taking a picture with flash enabled. If your phone does not go black then there’s a big possibility that your battery has gone faulty. Try replacing it with a new battery (preferable a genuine Samsung battery) then simulate the problem if it occurs again.

The next thing you should consider is the microSD card that you are using. Try taking it out first then take a picture with the flash enabled. If the problem goes away then chances are your microSD card is faulty. Just replace it with a new one.

Another factor that may be causing this problem is the app itself. You will need to clear the cache and data of your Camera app.

  • From any Home screen, tap the Menu key.
  • Tap Settings.
  • Tap the Applications manager.
  • Locate and tap the Camera application
  • Tap Clear cache
  • Tap Clear data

You might also try downloading any of the third party camera apps from the Google Play Store and check if the issue is still the same when you use them.

One last step that needs to be done in case all of the above steps fail to solve the issue is to do a factory reset on your phone. Just make sure to back up your data first.

  • Turn off the device.
  • Press and hold both Volume Up and Volume Down keys at the same time.
  • Press the Power key only until the phone vibrates once, then release only the Power key.
  • Continue to hold the Volume up and Volume Down keys until the Android System Recovery screen appears.
  • Press the Volume Down key to highlight wipe data / factory reset.
  • Press the Power key to select.
  • Press the Volume Down key to highlight Yes – Delete all user data.
  • Press the Power key to select.
  • Press the Power key to reboot.

If after performing the factory reset and the problem still persists then this could already be a caused by a faulty hardware. You will need to bring your phone to an authorized service center for checking.

S2 Does Not Charge

Problem: Our Samsung S2 would not charge.  So we bought a new battery and a wall battery charger and let the new battery charge for 24 hours.  When we put the new battery in the phone it said it was only 12% charged.  The phone will not charge at all with a battery charger cord.  If the old battery died, does the phone need some sort of reset?  If it needs to go to a technician, where can we send it?  This is a Straight Talk Samsung S2.  I’m looking forward to hearing from you.

Solution: No reset is necessary for the Samsung Galaxy S2 if you replace its old battery with a new one. You mentioned that your phone will not charge the battery but the battery can be charged externally using a wall charger. Try to check if the microUSB port on your phone has some dirt or debris on it. This usually causes charging problems. If there are aby present then you can clean it using a toothpick. You should also check if there are any damages (bending, bulges, cuts) on the microUSB port of your phone.

One other step that you also need to do is to try to use another USB cord then connect your phone with the new battery inserted to a computer. If it charges normally then the previous USB cord that you were using might be defective.

If the above steps fail to resolve the issue then you may need to send your phone to an authorized service center. Unfortunately, we don’t have information on the service centers in your area so you will have to search for it online or ask your friends if they know of any good technicians in your area.

S2 Does Not Turn Fully Boot

Problem: My two year old Samsung Galaxy S2 won’t turn on. The battery is completely charged and the phone itself isn’t even hot. I’ve tried to turn the phone back on, but it doesn’t totally starts. When I try to turn on the phone the only things I can see is the battery icon and it always says that the phone is charging and I can also see the text “Samsung Galaxy S II GT-I9100” i can’t come any longer than this. The phone have been like this over a year now. What can I do?

Solution: You might want to try entering recovery mode and do a factory reset on your phone. I’m assuming that since this issue is more than a year old already you don’t have any important data stored in your phone.

  • Turn off the device.
  • Press and hold both Volume Up and Volume Down keys at the same time.
  • Press the Power key only until the phone vibrates once, then release only the Power key.
  • Continue to hold the Volume up and Volume Down keys until the Android System Recovery screen appears.
  • Press the Volume Down key to highlight wipe data / factory reset.
  • Press the Power key to select.
  • Press the Volume Down key to highlight Yes – Delete all user data.
  • Press the Power key to select.
  • Press the Power key to reboot.

If for any reason the above procedure fails to resolve the issue then your next step is to use the latest Kies software to fix your phone. You will need a computer running the latest Kies version and a working USB cable.

  • Start Samsung Kies on your computer
  • Connect your phone to your computer using a USB cable.
  • Ensure that Kies recognizes your device by looking in the upper section of the left-bar navigation menu. Your device should be listed.
  • In the top left corner hit “tools” tab
  • Click the emergency firmware recovery choice
  • Just ignore the “Emergency recovery using the recovery code” and just click on “Emergency recovery” then click ok
  • Follow the instructions on the screen to recover your phone firmware

S2 Not Getting Latest Software Update

Problem: I have the Samsung S2/II T989 with Android OS v4.1.2.  The current Android OS version is 4.4.4 KitKat.  Why don’t I get the most current OS version supported, regardless of the phone’s model number? In the future I would like to get a phone where I can get the latest OS updates. What phone would that be?

Solution: For mobile phones there is a set period of time that the manufacturer or carrier will be able to support its software upgrades. The reason for this is that it takes a lot of manpower hours to develop software updates for a particular device. For some reason, manufacturers and carriers would rather devote these hours to newer popular devices thus old models are usually left with older software versions.

You can however update your phone to the latest software unofficially from the various Android developer communities. If you want to tinker with your phone then you can install a custom ROM on it running on the latest Android version.

If you want a phone that runs on the official software that gets the latest updates then you may want to check out the Nexus line of Android models. These models get the latest software updates as soon as Google releases them.

S2 Is Unresponsive/ Freezing

Problem: I own a Samsung S2 T989 and it keeps on freezing then rebooting on its own.  I tried updating the software but it failed. What do I do?

Solution: The first thing that you will need to check is the amount of RAM your phone is working on. The more RAM your phone has the more responsive it will be. The lesser RAM it has to work on the slower it will be. With less RAM to work on your phone will usually freeze or even reboot on its own.

To troubleshoot RAM related issues you first have to restart your phone. This refreshes the RAM and frees up its memory blocks of stored data.

Once your phone is turned on its time to take steps to reduce RAM usage.

  • Remove some widgets from Home screens (especially ones that update or have animation).
  • Turn off the live wallpaper.
  • Remove all unused Home screens.

Manage your apps

  • If a problem starts after installing a new apps, uninstall all new apps.
  • Keep your apps updated.
  • Read reviews of your apps in the Play Store to see if they are causing issues for others. Not all apps work well with all phones.

If the above steps fail to resolve the issue then your next option is to wipe the cache partition of your phone. This clears out the system memory.

  • Turn off the device.
  • Press and hold both Volume Up and Volume Down keys at the same time.
  • Press the Power key only until the phone vibrates once, then release only the Power key.
  • Continue to hold the Volume up and Volume Down keys until the Android System Recovery screen appears.
  • Press the Volume Down key to highlight wipe cache partition.
  • Press the Power key to select.
  • Make sure Reboot System Now is highlighted and press Power key to reboot.

One last troubleshooting step that you can perform is to do a factory reset. This deletes data stored on your phone so you have to make a backup.

  • Turn off the device.
  • Press and hold both Volume Up and Volume Down keys at the same time.
  • Press the Power key only until the phone vibrates once, then release only the Power key.
  • Continue to hold the Volume up and Volume Down keys until the Android System Recovery screen appears.
  • Press the Volume Down key to highlight wipe data / factory reset.
  • Press the Power key to select.
  • Press the Volume Down key to highlight Yes – Delete all user data.
  • Press the Power key to select.
  • Press the Power key to reboot.

S2 Google Sign in Error

Problem: I used my google account to sign in and it was all good for a few hours. Then randomly I will get notifications saying Sign in error for my email address I add the password and will not log in? I have made it gone away when sometimes going into google setting app on the Phone But is there a reason this is happening? Please help

Solution: The first thing you need to verify is if this is an account related issue or if it is a phone related issue. To check if it is an issue that concerns your Google account just log in your phone using a new Google account. If you don’t have another Google account then I suggest you create one just for testing purposes.

If the problem does not occur on the new account then the problem may be with your old account. Try to change the password of your old account using a web browser from your computer. Once the password has changed try logging in with your old account on your phone.

For phone related causes you will need to start your phone in Safe Mode. This allows you to check if certain third party apps are causing the issue.

  • Remove the battery from the phone.
  • Re-insert the battery.
  • Press and hold the Power key.
  • When you see the logo on the screen, release the Power key. Immediately after releasing the Power key, press and hold the Volume down key.
  • Continue to hold the Volume down key until the device finishes restarting.
  • ‘Safe mode’ displays in the lower-left corner. Release the Volume down key when you see ‘Safe Mode.

Once in Safe Mode observe your phone operation and see if the error message still appears. If it doesn’t then an app may be causing this. Try to find out what that app is and uninstall it.

S2 Cannot Send/ Receive Text Messages

Problem: Hi, not sure if this is a phone problem or a service problem but I am not able to send/receive any text messages. No one is saw what I sent when I ask them and I could see no one’s messages when they ask me. I tried updating my PRL/Profile, I tried force stopping the app and clearing the data, I uninstalled the app and then reinstalled but all this did not fix it.

Solution: Check your phone if you are getting any signal. If the signal strength is good then try making a call and see if you can. You should also contact your network provided and ask if there are any issues in your particular area.

If you have access to another SIM then try to insert it in your phone and try sending a text message to that SIM. If you receive the message then the problem is with your SIM. You may want to have it replaced.

If the above steps does not solve the issue then we proceed in troubleshooting the phone itself. Are you using the stock messaging app? If not then I suggest in using it and uninstalling any third party messaging app that may be installed in your phone.

Try sending a message to yourself using the stock messaging app. Does the message send out normally? Or do you see an error message that states the message could not be sent?

Backup all data in your phone and do a factory reset.

  • Turn off the device.
  • Press and hold both Volume Up and Volume Down keys at the same time.
  • Press the Power key only until the phone vibrates once, then release only the Power key.
  • Continue to hold the Volume up and Volume Down keys until the Android System Recovery screen appears.
  • Press the Volume Down key to highlight wipe data / factory reset.
  • Press the Power key to select.
  • Press the Volume Down key to highlight Yes – Delete all user data.
  • Press the Power key to select.
  • Press the Power key to reboot.

Once your phone has fully rebooted try sending yourself a text message. If it doesn’t send or you can’t receive the message then this may already be caused by a faulty hardware. You will have to bring your phone to an authorized service center for checking.
