Galaxy S2 Won’t Boot Up Completely

Problem: Hiya, my Galaxy S2 won’t turn on when you switch on it shows the Samsung home screen then goes to the O2 screen and after a second switches off an then starts over again in an endless loop or until the battery is removed it does this with or without the SIM card in the phone. I hope you can enlighten me as to the problem and solution. Kind regards, Joe.

Troubleshooting: Hey Joe, it looks like the Power key in your phone is stuck. Try pressing it many times to see if you can fix it, if not, then you really need help from a technician. There is also a possibility the Power switch was damaged.

Possible Galaxy S2 Microphone Issue

Problem: Hi there, dunno if you still help people, but I’m having a serious issue with my S2. When I receive a call, the caller cannot hear me at all, but i can hear them. This started recently about a week ago. I have not installed any upgrades or updates to the phone since last year December. I’m still running Android version 2.3.4, Phone Model GT-I9100.

If you please can help, I don’t want to spend R350 at the Mobile shop for them to just look at it. Kind Regards, Wiehahn.

Troubleshooting: To make sure it’s not a serious hardware issue, try to call someone and use the speakerphone. If the person on the other line can hear you, then it could be just a microphone issue. Galaxy S2 has two microphones, one on the top and one at the bottom near the microUSB / utility port. The mic that has a problem is the one at the bottom. First thing to do is check if there’s dirt in the hole. Try to clean it by blasting compressed air. If the problem persists, then there’s no other option but to pay for services of the tech.

Galaxy S2 Won’t Power On With New Battery

Problem: Hello, hoping you can assist with my phone issue.

My backup phone (S2) doesn’t turn on. So I got a new battery and the charging icon doesn’t even show up. The blue light flickers ever so slightly.

I think it may be the three prongs at the back of the phone/battery space.

Any thoughts on how I can get this phone to turn on? Thank you for your help. — Dennis

Troubleshooting: Hey Dennis. Have you checked the prongs? If they are aligned well, then there’s no problem with them. If the phone didn’t have physical or water damage, the problem could be in the daughterboard where the USB charge port is attached. It’s the same component that bridges the phone and the charger, and the battery and the motherboard. It could be defective and needs replacement. You need help from a technician to get this figured out.

Galaxy S2 Gets Extremely Hot

Problem: Hi, please I need your help with my Samsung S2.I gave the phone to my little sister and she clumsily spilled water on it, out of panic she try whisking the water out of it by gently shaking it out, then she put in the battery and switched it on. It came on then ever since then its always been EXTREMELY HOT on the lower right side of the screen. Since then whenever I plug in the charger it shows this warning ‘charging paused, battery temperature too high’ then it goes off. I’ve done a factory reset all to no avail. On opening the board, I realized that its a specific chip with letter “AAQ BHN” located at the lower right part of the board that gets very hot, it even burned me. Please what caused it and what can I do? — Ajayi

Suggestion: Hi Ajayi! That’s one of the effects when liquid enters the device and touch any of the components. The AAQ is a charging and USB controller IC and it’s expected to be damaged if there’s a short circuit in the phone. The error you’re getting is an indication the IC is busted and can no longer determine correct battery temperature. In other words, you need to replace this IC to get the phone to work again.

I think the IC can be bought online for, at least, $60 but then you’ll have to pay for the shipping, plus the tech and there’s a possibility there are other components that were damaged. To sum it up, I think it would be more practical to buy a new phone than to get it fixed.

Galaxy S2 Freezes On Home Screen

Problem: I have a Galaxy S2 it lets me turn on but as soon as it goes to my screensaver page it freezes and wont let me do anything do you know what is wrong and how much it will cost to fix. I am unable to get past this. Thanks, Jason.

Troubleshooting: Hey Jason. It could be a minor firmware problem and it may not be necessary to get a tech fix it for you. The first thing I want you to do is boot the phone in safe mode just to see it makes a difference. If the phone still freezes in safe mode, then there’s no other way to fix this but hard reset.

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.

You can also make the phone boot in safe mode by following this simpler procedure:

  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.

Master Reset

  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.

Boot In Recovery Mode Without Using Hard Keys

Question: Hi Harold, I’m really having a very annoying problem…and I hope you will give me a solution for it.. I have Galaxy S2 (GTI9100G) variant.. and the volume up and down keys don’t work, and I want to go to recovery mode to root it, but i couldn’t find a way to go to recovery mode without using the volume key.

I want to know if there is a way to go to recovery mode without using volume key, or if there is any way to root it by flashing the rooting software (by odin) without losing the Rom installed on it (official rom)… I ddnt want to install a custom room.

BTW.. the volume key can not be fixed, because I have to change the LCD screen to fix it (the LCD screen installed on it is for the (GTI9100) variant. that’s why the volume key is not working because it’s not compatible with the screen… Thanx — my regards … Ibrahim

Answer: Hey, Ibrahim! You need to root your Samsung Galaxy S2 first. There are several one-click root processes available online, find the one that best suits you. After you have rooted your phone, install Quick Reboot app from Play Store to allow you to reboot in recovery mode without having to use the hard keys.

Turn Off Photos App in Galaxy S2

Question: Hi, could you please help? How can I turn off Photos app on Samsung S2 mobile? I accidentally click on Turn On button, but now I want to switch it off. Your quick response is much appreciated. Thanks, Orsi.

Answer: You can’t. It’s a default app you can’t turn it off the way you want it. You can, however, uninstall it if you have root access. But if your phone wasn’t rooted, then you have no choice but to deal with it.

Galaxy S2 Stuck At Samsung Logo

Problem: Hi I own a Samsung Galaxy S2 and its been working fine however there is a problem. My phone froze so i decided to turn it on, it comes on but it stays at the Samsung pag with it just saying SAMSUNG. Any suggestions i need help please get back to me as soon as possible. — Anah

Related Problem: My 4 year old S2 switches on and displays the Samsung logo with the rotating blue circle but then loops around thus and does not go into a boot sequence. I have tried it with two batteries fully charged with and without the power connected. It looks like the booting sequence has got corrupted in some way. Any ideas. Thanks, Dave.

Troubleshooting: Hi Anah, I suggest you try to boot the phone is safe mode first. If it froze without apparent reason, it could have been just a glitch. Booting in safe mode and booting back to normal mode will often fix this problem.

  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.
  7. Now reboot your phone normally.

If the S2 is still stuck at the logo, then you need to wipe the cache partition and reboot one more time to see if it makes a difference.

  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.

If all else failed, however, it’s time you performed full hard reset.

  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 Won’t Turn On After Series Of Issues

Problem: Hi Droid Guy, in the last two days my Samsung Galaxy S2 has been playing up, it has been heating up, turning itself on when I have powered it off, unlocking itself and opening the voice command (as if the centre button was pushed in). Yesterday it went completely flat so I put a battery that was half charged in it. My phone turned on but said the battery was only 13 percent charged. Once it reach 10 percent it turned off, I then put it on charge but no charging symbol appeared. I have tried three different batteries and left them all to charge for a few hours each but still my phone wont turn on. I know that all three batteries and the charger is fine because they are being used in other phones. I hope you can tell me what’s happened to it. — Chloe

Suggestion: Hi Chloe. It sounds like it’s a hardware issue. The behavior of the phone suggests that there’s an issue with the USB charging port, a component that bridges the battery and the motherboard. More often when it’s damaged, the phone won’t turn on after a series of power-related issues. I suggest you bring the phone to a technician and have it sorted out.

Insufficient Storage Memory on Galaxy S2

Problem: Hi. My name is Angela and I have a galaxy s2. Recently my phone has been telling me to delete software, music, pictures, that there isn’t enough storage space. I then went to walmart and purchased a sd card thinking maybe if I move everything over to it would allow me to access my gallery. It didn’t work. I have factory reset 3 times. I went to my files and tried deleting unnecessary files but when I check the box and confirmed deletion it would not delete. I went to google play store downloaded a file manager and tried to delete there too and still didn’t delete anything. I went through cm security and deleted 127 pictures from the gallery and other apps such as petapic and bright cam. That also did not help me at all. I still get the same message. Last thing I have recently done is rebooted my phone and clear cache but nothing. I just don’t know what to do anymore. I cant even use my camera because its useless. It doesn’t save my pictures. Can you please help me out? I would greatly appreciate it. Thank you.

Troubleshooting: You said you already performed factory reset. That should have worked but since it didn’t, try this:

Go to the dialer, and type EXACTLY star pound 9900 pound (*#9900#). The menu automatically comes up (no need to send or anything). Select the delete dumpstack option (second one down on your phone).

If it still failed, then hard reset will fix it for you:

  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 Charges But Won’t Power On

Problem: I read your blog regarding this phone not turning on. I can plug the charger in and get the battery icon, but it still won’t come on. Battery shows full charge. — Glenda

Troubleshooting: It sounds like it’s a very minor hardware glitch. It can be fixed by soft reset:

Soft Reset Procedure

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.

Pre-install Apps Crash on Galaxy S2

Problem: My phone freezes after i send a text or call somebody and it comes up on screen, “Unfortunately messenger has stopped” when i have text and says” Unfortunately contacts has stopped” when i have called someone, also when i try to get onto my logs to see who i have called it also freezes and says “Android.process.com has stopped”, also comes on screen “tw viewer stopped.”

Troubleshooting: It’s a firmware issue caused by a service or app. Try to check if there’s an available update for your phone, I’m sure firmware update can fix it. If not, then factory reset will, however, you need to backup all your data first because they’ll be deleted.

  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 Won’t Boot Up

Problem: The S2 will not go past the black Samsung Sll splash screen, battery is fully charged, I have tried the reset option ie power, home & volume down but cannot get the reset option to load, is there any other options I can try?

Connection to a pc via the USB port does not show the device connected so I cannot use kies to reload the os /firmware. Can you help at all please. — Peter

Troubleshooting: Maybe you’re doing it wrong. For the phone to successfully boot up in recovery mode, it must be turned off first. Open the back panel and remove the battery, then follow these steps:

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

Galaxy S2 Can’t Be Recognized By Computer

Problem: Good morning, I’m having trouble with my S2, Its over two years old now and has been a good phone, but just started with this problem in the last few days. It is no longer recognized by my laptop, all is fine when I connect my old samsung wave, my reserve phone! I thought it might need a replacement usb port as seen on you tube, but I have other issues which may be connected with it. It started with the drive mode flashing up, which would come and go interfering with music playback. When I turn it on whatsapp comes up with a date and time time error, which sometimes is right and sometimes not. It won’t turn off right either, it takes ages and then flashes up the battery level as if it were still plugged into the charger, and keeps repeating that until I take the battery out. The battery seems to be charging normally, but whether I’m using the supplied wall charger or a USB to the laptop, if I unplug it the charging symbol remains for 20 seconds approx! And a few seconds delay sometimes before it is lit although sometimes it still beeps, but I can’t get connected to the laptop, says device not recognised, which is a downer as I would like to check Kies for updates to the firmware(about a year since I last did that).

What do you think? Would appreciate your help!

Kind regards, Craig.

Troubleshooting: Hey, Craig. Based on the problems you mentioned, it sounds like there’s an issue with the USB or utility port. Please check if there’s one misaligned pin, if there is, you can simply re-align it so it won’t touch others. Yes, this problem could be as simple as that but the challenge is finding the pin that’s misaligned because these pins are so tiny and thin.

If, however, all pins are properly aligned, the USB charging port needs replacement. But I’m assuming other devices can be detected by your computer.

Galaxy S2 Encryption Failed Error

Problem: Hi, I’m having this issue with my S2 which suddenly died whilst on a call.

When I tried restarting it, it showed me zero battery (had this issue a couple of time before but putting back to power would work).

After providing some power, I tried restarting but all it would say is “Encryption Failed – Unable to complete encryption due to interruption. Perform factory data reset (erasing all your data) before use. After resetting, try encrypting device again” and the only button to “Reset phone”

I’ve tried removing battery, sim card etc, but I keep getting above option. The phone is never rooted, nor encrypted ever.

To reach above screen, it gets past the initial Samsung screen, then the network provider screen and finally Samsung screen as well. It takes it around 10 seconds to reach the stage where it give above failure message.

I’ve been going through your forum (link below) and tried the steps given in option 6 i.e. #6. Galaxy S2 will not boot up, but no luck. Only difference (after following those steps in option 6) is on bottom left corner, I see the safe mode button on screen, but nothing happens when I touch it. Its not selectable via the volume keys (volume keys actually change volume when in above mode). The power or home button doesn’t do anything. In above mode, if I hold the power key, it just gives me two options – “Power off” and “restart”. Please help.

Thanks in advance. If you think reset phone is the only option, what tools would you recommend to recover data, esp on a mac? Thanks, Dinesh.

Troubleshooting: The Encryption process often takes more than an hour after you chose to encrypt the phone. So, if the process failed, you will be getting that error message after an hour or more. If you didn’t initiate the encryption process, then someone did or it’s just another issue with the firmware and now you will need to reset the phone.

You said you reached safe mode, that’s good. While in that state you can backup all your data. I will recommend Samsung KIES. After you backed up your data, 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.
