Galaxy S2 Cannot Boot Up Successfully

Problem: Hi there! I have an old S2 which my kids use as a mini tablet for apps and games etc. It has no SIM, however in order to download apps I connect it to the home wifi. My daughter was playing a game when the screen froze and the phone was quite hot. The home button wouldn’t work and I couldn’t power off either. So I removed the battery, waited until it cooled and tried to restart. It did not vibrate, however the initial Galaxy graphic did appear but it didn’t go any further.

I tried another battery and same thing happened, the original battery worked fine and showed 90% charge on another S2. Next I tried a couple of suggestions from the problems on your site. In particular the OS reset of vol down-home-power, but it was again stuck on the download screen (possibly because it didn’t have the wifi enabled before it froze?). See attached images.

What solution should I try next? Many thanks, Jill.

Solution: Hi Jill. There is a possibility that the phone overheated that’s why it froze. Good thing you let it cool down before turning it back on. The thing is, the app that was running when the phone froze may have caused some conflicts that’s why the device can’t boot up completely. I suggest you try booting it in safe mode first. Please follow these steps:

  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.

Once the phone has successfully booted in safe mode, just restart it so that it would boot normally. Most of the time if the problem was caused by an app that crashed, this procedure can fix it. However, if the phone cannot boot in safe mode or still stuck during boot up, booting in recovery mode and clearing the cache partition will take care of it. I understand you already attempted this but you reached “Download Mode” because you pressed the Vol Down key instead of Vol Up. To wipe the cache partition, please 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 key to select.
  7. Make sure Reboot System Now is highlighted and press the Power key to reboot.

Galaxy S2 Can’t Get Good Service

Question: Hello, I have a Samsung Galaxy S2 Skyrocket that has issues getting service. I’ve been able to get good service everywhere until about a year ago, when for some reason, I’d get service maybe for a couple hours a day. That only lasted a week, but now the problem is back, and has been going on for about two months. When I got this phone two years ago, the digitizer was broken so I had to replace it myself. Could the connection be loose? Is this problem common? Any info would be greatly appreciated. Thank you! — Ben

Answer: Hey Ben. I don’t think it’s a connection issue because if it were, the phone couldn’t get good service soon after you replaced the digitizer. As you said, the problem started about a year ago so there could be something else. It’s just isn’t clear what you meant by “service.” It could have been helpful if you specified that the problem is with call, text or internet, or your phone is having a difficulty detecting cellular signal.

Service-related problems are common but their causes may vary. There are times when it’s a network issue and sometimes phone problems. It’s difficult for us to determine your case as we don’t know exactly what kind of “problem” you’re currently experiencing. Feel free to email us back and if you could, please provide more details.

Galaxy S2 Doesn’t Charge At All

Problem: Hello! I really really need help with my Samsung Galaxy S2. It isn’t charging at all and I’m pretty sure the battery isn’t the one at fault as it could actually be charged when being put into another friends S2. As of now my phone is completely dead with 0%. It cannot even be turned on and when I actually do plug in the charger, the (charging/loading) sign does not appear at all in which it’s supposed to appear in the middle of the black screen if it is in the midst of charging. I really love this phone a lot and I don’t want anything to happen to it. Thank you so much for reading this and please help me. Thank you and God bless.

Troubleshooting: Okay, so you’ve out the possibility that it’s a battery issue. That’s good. How about the charger? Did you try to use your friend’s charger for S2? If the phone still won’t charge even if you use a different charger, then we’re looking at a possible USB charging port issue. This component serves as a bridge between the charger and the battery. If damaged, the current cannot get to the battery, thus, charging would be impossible. A local technician may be able to help you or the tech support of your service provider.

Galaxy S2 Won’t Turn On

Problem: About 3 weeks ago I knocked my galaxy s2 in the toilet by accident. After this the phone has worked perfectly for 3 weeks. After the 3 weeks my phone wouldn’t power off so I manually took out the battery and the phone shut down. Now I have tried everything but my phone won’t power on however when it is on a charger the battery icon is displayed and shows how charged the phone is. The phone is really dry and I have used rice and hairdryer trick. Please can you help me try to get my phone back to life because I have looked at the website which has given me no luck 🙂

Useful information: galaxy s2 black, perfect condition, new battery. I would be very appreciative if you could help me. — Harry

Troubleshooting: Hey Harry. Based on your description, it seems to me like this is a Power button issue; it could be stuck or totally damaged. But I really can’t confirm that because you never mentioned what happened when you pressed the Power button. But I guess when you pressed the Power button, the phone wouldn’t respond so you took the battery out. But since the phone wouldn’t when you press the switch, you couldn’t turn it back on. My advice, have a technician take a look at it. Again, the Power switch may just be stuck or damaged.

Galaxy S2 Speaker Won’t Sound Off

Problem: Hello, I have had my Galaxy for 2 years now, for about a year there has been no sound coming out of my speaker, yes I checked the volume settings and tried to restart my phone…take the battery out. NOTHING IS WORKING!!! I am like ripping my hair out just to try and figure out how to get the sound to work again. PLEASE HELP!!! — Rebecca

Troubleshooting: Hi Rebecca. There are two possibilities here; the problem could be with the speaker itself or with the phone’s built in amplifier. Use headphones and play a sound or a music track to know if there’s audio streaming out. If yes, then it’s just a speaker problem, otherwise, it’s the amplifier. Either way, you need to have the phone checked by a technician. If it were just a speaker problem, it can easily be replaced.

Calls To Galaxy S2 Go Straight To Voicemail

Problem: Hi. I am having a problem with my phone, it won’t allow me to make or receive calls and sms. The phone is on and the signal bar is full but people say my phone is going straight to voice mail when they call me. After I switch my phone on/off a few times then the messages will come through eventually. What can I do to fix the problem. When I try calling or sms’s it says connection problem or IMM problem. Please help. Thanks. — Dev

Suggestion: Hey Dev. During my tenure as a tech support for a wireless provider, I encountered a lot of problems that are exactly the same as the one you’re currently experiencing. It’s not something you can fix on your end, so call your service provider. There’s a common tool that fix this problem in one click.

Galaxy S2 Froze While Using The Camera

Problem: I have a Samsung Galaxy S2 and i was taking a picture of my new phone case to send to a friend and it was quite dark so i turned the flash on. When i took a picture, the phone froze and the flash and the picture i took are still stuck on the screen. I have pressed the home button but it is staying and i have tried to turn it off but it isn’t working. Its been like this for about 10 minutes now so i really need some help as i cant pick it up without the flash blaring across the room. Thanks, Freia.

Suggestion: Hey Freia. I assume you’ve already figured out how to turn it off or the phone may have already depleted its battery. If ever it happens again, remove the back cover and pull the battery out. It will surely turn the phone off. If the same problem happens, try clearing the cache and data of the camera app. Doing so usually fix app-related problem. However, if it happens multiple times a day, then there’s a possibility that it’s a hardware issue.

Retrieving Info From S2 That Won’t Turn On

Problem: Hi Guys, need some advice. Yesterday my Samsung Galaxy S2 was working OK, then in the afternoon I went to use it and found that it had only a black screen but seemed to be on as the icons are lit along the bottom of the phone. I changed the battery with the one from my partners phone (his battery was 100% charged) and still nothing. I tried a few troubleshooting tips from the Samsung online chat but nothing seems to work. i.e., they told me to try to turn it off so that the lights were not on, take the battery out, replace it and then press the home key the volume up key and the power on key at the same time, wait for it to vibrate and then release the power on key. Nothing happened.

I have had the phone for two months and have loads of passwords stored in the memo app on it, hence I am reluctant to try to send it back to the dealer (who may I add seems a bit dodgy anyway). I just really want to get the information off the phone (and before you say try connecting to computer, this doesn’t work have tried), as I know have a new Samsung S3 NEO. I hope you can give me advise on how to retrieve this information. Kind regards, Suzanne.

Troubleshooting: Hi Suzanne. There’s no way you can retrieve those information if the phone stays off. It is, therefore, necessary to, at least, try to bring the phone back to life. The first thing I suggest is to do the soft reset:

  1. Pull the battery out of the phone.
  2. Press and hold the Power key for a minute.
  3. Place the battery back in.
  4. Attempt to turn the phone on.

If the phone refused to boot up after the soft reset, try booting it 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.

If the Galaxy S2 successfully booted up in safe mode, then use that opportunity to retrieve the information you don’t want to lose and delete those you don’t want others to see in case you would need to send the phone in for repair.

However, if safe mode failed, then the last option is to try booting the phone in recovery mode again:

  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.

If all else failed, you already need the help of a technician.

Galaxy S2 Won’t Turn On Even With Charged Battery

Problem: Hi, I’m wondering if you know what’s going on with my phone. I have a Samsung Galaxy S2 and when I plug it into the charger the green battery icon appears and says 100% but when I press the power on button nothing happens, except occasionally the battery icon changes to grey as if it is completely drained again, but then quickly changes back to green 100%.

I’ve tried with an ordinary charger and the USB cable to my laptop. Do you think I simply need a replacement battery or could it be more than that? Thanks for your advice. Kind regards, Kirsty.

Troubleshooting: Kirsty, based on your description, I think it’s just a minor glitch and can be fixed by a simple soft reset procedure:

  1. Pull the battery out of the phone.
  2. Press and hold the Power key for a minute.
  3. Place the battery back in.
  4. Attempt to turn the phone on.

Now, if the phone refuses to turn on after doing the procedure, then try booting it is safe mode. If that fails, too, try recovery mode. The purpose of these procedures is for us to know if the device is still capable of booting up because if it is, then there is a chance it can be fixed without having to buy a new battery or having the phone checked by a technician. However, if all of these procedures failed, I suggest you immediately bring it to a tech because there’s no guarantee buying a new battery is the solution.

Galaxy S2 Notification Bar Can’t Be Pulled Down

Problem: Hi. I hope you can help. I am not able to drag down the notification bar on my phone. It was fine until a couple of days ago and I haven’t knowingly changed any settings. I have looked through your FAQs but haven’t found anything relevant so hope you can help. Many thanks. — Alison

Troubleshooting: Hi Alison. There is a possibility that this was caused by an app. I suggest you boot the phone in safe mode first and try to pull down the notification panel. If it works normally, then find the app that’s causing this and disable or uninstall it. However, if you still can’t pull it down in safe mode, it’s possible touch commands don’t work in the top part of the screen. Launch the dialer and enter this code *#0*# and then choose “touch” and test the top part of the screen.

Now, if it’s a touch issue, have the phone checked by a technician. However, if your test shows that the entire screen is functioning fine, backup your data and perform factory reset as it is apparently an issue with the firmware.

Galaxy S2 Auto Connects To Secured WiFi Network

Problem: Hi, I have an issue with my phone. If I accidentally click a wifi network that I don’t know the password, there is no way for me to forget it or go back to the list of available networks. If I turn off wifi, i use data, if I turn it on, it auto connects me to this wifi that I can’t use. I would like to forget that network and then add the network that is really my own wifi. How can I do this? — Kristen

Troubleshooting: I wonder, how can the phone auto-connects to a secured network without the user entering the password? Also, I’m interested to know what screen you see when you touch WiFi under Settings. If you can turn on and off WiFi via Settings, then you must be able to display available networks when you hit the word “WiFi”. But I take your word for it, say you cannot get into the screen that lists down available networks. I suggest you boot in safe mode and get into WiFi again via Settings. Furthermore, let’s assume these procedures didn’t work, then there must be an issue with the firmware itself and I suggest you reset the phone to its factory defaults. Of course, don’t forget to backup your data before doing that.
