Samsung Galaxy S2 Problems and Solutions [Part 1] [Part 2] [Part 3] [Part 4]

Now, here is one of our readers who want to say thank you:

Thanks guys, been having awful trouble with my Samsung Galaxy S2 not being to download anything, getting hot…etc. Fix no. 7 worked amazingly, just typed in the code deleted dump stack and voila, I am able to download all the games I deleted due to insufficient storage space… Wow! Kind Regards – Alan

Problems and Solutions

#1. Galaxy S2 has problematic buttons

Problem: Hi, I don’t know if this is a common problem or not but all the time my menu button goes nuts. I’ll be using Firefox or Amazon and the menu just pops up by itself and I have to keep tapping the screen to make it go away. And the back button also has some problems, like when I send/receive a text it’ll just stop working for 10-15 seconds. Its really frustrating, any help would be greatly appreciated. Thank you, Eddie.

Solution: I know how frustrating it is, Eddie. But I believe it’s more of a hardware issue than a glitch. The best course of action is to have it checked as soon as possible. There is, of course, a possibility that it’s a firmware issue, so, it is logical to perform factory reset just before you bring it to a tech.

#2. Galaxy S2 became hot, won’t turn on

Problem: Dear sir, I hope you will help me and give a best solution as soon as possible. My set was showing a problem (it was hot from back side cover after a small period of time when I used) from last two weeks and today it turn off. My Galaxy S2 won’t turn on when I press the power button. Is there a way to solve this?

Solution: I believe your battery is now faulty and it was the one that caused the heating up of the phone. It is also the reason why your phone won’t power up; it may not be able to hold a charge anymore. Of course, the immediate remedy for this is to buy a new battery kit, or have the phone checked thoroughly by a technician.

#3. Galaxy S2 keeps hanging and freezing

Problem: Hey. My Galaxy S2 froze a couple of days ago. Now it will turn on and respond for a bit, but will always freeze (or reboot). While it’s on it won’t connect to my mobile network or wifi. I may have spilled just a couple of drops of juice on the phone, but I had a protective screen on it and I can’t imagine any having entered the phone. Anyway, I tried clearing the cache, then I did a factory reset. Same problems persist. I opened it and tried cleaning the board with a compressed gas duster. There was nothing that stood out to me when I had the phone open…looked very clean and proper. If you have a magic cure, that would be wondrous. Thanks!

Solution: Oh yeah, how I wish I have a magic wand so I can easily fix problems but I don’t. Just like the previous two problems, yours could also be hardware related and the best way to find out what really is happening with the phone is have it checked up. Sorry, but when it comes to hardware issues, there’s only so much we can do about them.

#4. Galaxy S2 camera blurry

Problem: The camera on my s2 taking pictures is blurry I have tried everything but nothing is working. I need step by step guides on other ways to fix the problem. Please help I’ve had enough.

Solution: Just make sure the lens is clean and don’t move around when taking pictures. I think you already did this, didn’t you? I am sure this isn’t a firmware or software issue; the component at fault here is the camera sensor itself. You need to have that replaced.

#5. Galaxy S2 can’t access mobile data

Problem: Hi there, I was reading through your guide on how to fix common problems with the Galaxy S2. For the past month, I haven’t been able to access data on my phone. I tried a factory reset and it didn’t fix the problem. Data is turned on, I pay my bills, and I’ve got the right network selected. I’ve tried everything I can think of, including bringing my phone to my service provider, but nothing works. Can you help me? Thanks, Sarah.

Solution: Your service provider should have been able to provide you explanation why you can’t access ‘their’ network through your phone. Honestly, when it comes to network problems, your service provider or carrier has the correct answers. But in your message, there’s one thing you haven’t mentioned–the APN Settings. Perhaps your service provider changed the settings that’s why your phone can’t be able to connect to the network using the previous settings. Please call your service provider and ask for the correct APN settings and have the rep walk you through setting them up on your phone.

#6. Galaxy S2 deleting dumpstack

Question: I just read Part 3 of S2 problems and wanted to try your insufficient memory fix. Unfortunately the ‘delete dumpstack’ option does not show on my phone after dialling *#9900#

The nearest thing SysDump shows is ‘delete dumpstate/logcat.’ Is that the same thing? Phone is GT-I9100 running stock Android 4.1.2. Thanks!

Answer: Yes, it is the same as dumpstack. Terminologies vary all the time but they have the same meaning especially in Android.

#7. Multiple Galaxy S2 problems

Problem: I have a Galaxy S2. It was working fine for more than 2 years then three months ago, I started to have some problems:

  • Battery drains quickly and suddenly drops from 70% for example to 12% and sometimes to 0% and the phone goes off
  • Mobile never shuts down it always reboots, and cannot be turned on unless I go to installation mode and reboot
  • Battery flash when the mobile is charging (device turned off) keeps repeating itslef without showing how much the battery is charged
  • Mobile cannot be connected to laptop using USB

I have changed the battery but the second one got damaged very quickly. I took it to a mobile specialist and he changed the charging port, then all the problems were solved except the draining battery and its sudden death.

I want to change the battery but I am not sure whether it is the problem or not. The specialist was not very helpful. Can you tell me how to check what is the cause of this charging problem? The battery or something else. Thanks.

Solution: So what remain now is the draining problem and the random reboot. With hardware issue already put aside, all you can do is to observe the phone closely. Spend half a day observing it with all third-party apps disabled. Boot to safe mode and never open any app you downloaded or installed from the Play Store. If you’re going to make or answer some calls, feel free but be observant of your battery’s performance. I’m not sure how quick your device drains the battery but with all third-parties disabled, the phone could last way longer than before. Otherwise, it’s a battery problem.

In case the problem is caused by a third-party or pre-installed app and you don’t know which one, backup all your data and perform factory reset via the Recover Mode. That will bring the phone to its optimum settings and all any other problems associated with third-party apps or core services should be fixed.

Additionally, one of our readers suggested some procedures that works:

Hello, I don’t know if this is the right email address, but I have some solutions to problems with the galaxy s2. Laptop not recognising phone. This happened to me, every time I plugged it in I had to redownload the driver. Fidleing and faffing I found a better solution. Remove the SD card from the phone. Then your pc will recognise your phone. I believe it’s down to a conflict with the laptop /phone. Both recognise the external SDcard it as a storage device belonging to the other so neither access it. Thus this in turn can block the phone.

Also battery drain, yes this to has happened to me. Power was being eaten at an alarming rate. From full battery to dead in four hours. Try removing the SD card for a day and see if it still drains as quick. If it is the card it’s my theory that a garbled line has been written to the SD card. I found such a line on mine, deleted it and all was ok after. Though to find that out I put card in card reader and used pc to access it. I hope this is of help to some one. P’s love your app, especially the s2 fixes. Julian

#8. Google apps process stopped working

Problem: I saw your posting. I have a Galaxy S2 – T989 from T-Mobile. Over the last few weeks, I have been getting the error message and phone freezing “google.process.gapps” has stopped. I have gone to the download manager and “disable” but it does not resolve the problem. Your suggestions are appreciated. Thank you. — Todd

Solution: The thing about this issue is that it could related to all apps and services Google including the Play Store itself, the Play Services, Gmail, Google Search, Google Voice, etc. Thus, it is difficult to point out which one of these apps and services is causing the problem. But try to remember which of them were recently updated or used prior to this issue. If you can’t remember anything, try going to the Application Manager and look for Google Play Store and clear its cache and data–lastly uninstall its updates. While it is not so common, many Android users already encountered this problem and most of the time uninstalling Play Store’s updates fixes it. So, try that one.

#9. Galaxy S2 Wi-Fi and call problems

Problems: Hi there, I am on the Bell network and I have the Samsung Galaxy S2( Baseband Version I9100MUGMA5 with Android Version 4.1.2.). Ever since this version of Android, every time I turn on my Wifi, my cell phone re-boots. This is quite annoying. Are there any fixes for this?

My latest issue and biggest one of all. When anyone calls me and I answer with my cell phone, I can hear the person perfectly, but they cannot hear me. I don’t know what this problem can be.

If I use Bluetooth or the speaker phone, this works just fine as the caller can hear me. Ever hear of this problem? Any solution? Thanks, Pascal.

Solution: The first problem you mentioned may be caused by corrupt Wi-Fi cache. You need to wipe that off your phone’s memory by booting to Recovery Mode and wiping the cache partition. Here’s how…

  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 Home (GB only) or Power (ICS only) key to select.
  7. Make sure Reboot System Now is highlighted and press the Home or Power key to reboot.

The second problem, however, I think is caused by a busted microphone. You need to have the phone checked by an authorized Samsung technician or by your service provider.

#10. Android process acore stopped working

Problem: Good evening, I’m from Malaysia. I have a problem with my Galaxy S2. The problem is, a dialog box appears. the message were like this. “Unfortunately, the process android.process.acore has stopped.” Each time I entered the menu, the dialog box will appear and it will exit to homescreen. What should I do? Thanks in advance.

Solution: This is apparently an Android problem. I’m not sure what happened to your phone that the core Android service was messed up but the best course of action is to wipe the cache partition first. After that, boot your phone normally and see if the same problem happens. If so, try booting to Safe Mode and observe if it still persists. If it doesn’t, then there is at least one third-party app that’s messing with the system, find that app and uninstall it. Or, you can proceed to backing up your data and performing factory reset.

#11. New Galaxy S2 won’t boot up

Problem 1: My Galaxy S2 won’t turn on. It’s new and I’ve tried everything from resetting everything and taking out the battery and putting a new one in. It always gets stuck at one part. — David

Problem 2: Hi, recently the phone stopped turning on. It comes up with the provider’s start up menu but it freezes on a blank scree with SUMSUNG name on it. The phone is about 2.4 years old. Are there any fixes? Regards, Andrea.

Solution: You meant the phone won’t continue with the boot up process… there is a possibility that the Android system has some corrupt files needed to boot up. But the other possibility is that there could be some apps or service causing the problem. Wiping the cache partition via the recovery mode would often solve this kind of problem. But before doing that, try removing the microSD card first to rule out the possibility that the external storage device is causing all this.

  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 Home (GB only) or Power (ICS only) key to select.
  7. Make sure Reboot System Now is highlighted and press the Home or Power key to reboot.

Hope this helps.

#12. Galaxy S2 camera focus problem

Problem: Hi, sometimes the pictures made by my S2 phone are blurry (not focused). All my camera settings are ok. I saw some questions regarding the same problem on the internet. Do you have any suggestion how to solve this? — Jan

Solution: The immediate remedy to this issue is to clear both the cache and data of the camera app. If that doesn’t work, try using other camera app from the Play Store and the quality of the images are still the same, then it’s a sensor issue. There’s no better way to address it but to have it checked or replaced by a technician.

#13. Black dot on Galaxy S2 in camera mode – facing out

Problem: Hi there, thought I’d share this issue that my Samsung Galaxy S2 has had for approx. the last few months. When I click the camera to take a photo – in the upper left quadrant, there is a small black dot. I checked and cleaned the camera lens on the back, but it is not that – the issue is still there. What I did notice is that if I put the video mode on, there is no black dot, and also, if I switch the camera to the option, as if I wanted to take a photo of myself, there is no black dot. I was thinking this was perhaps a pixel issue, but now wonder if it could perhaps be software related. Any ideas? Sincere thanks, Annette.

Solution: If it were a pixel issue, Annette, the black dot will appear regardless of what application you’re using, or even if you’re on the Home screen doing nothing. So, let’s rule out that possibility now since you said it disappears when you’re on video mode. I never encountered this problem before but I know the most logical action to address this is clearing the cache and data of the Camera app. Don’t worry, you won’t lose any of your pictures. I am curious to know about this problem, so if you’d be so kind to send a screenshot, that would be very helpful.

#14. Galaxy S2 warning triangle, thermometer

Problem: Hi, my 2-year old S2 won’t switch on. It’s showing battery 3/4 charged but flashing over to a caution sign and thermometer I’ve taken battery out for half hour and put back it’s still doing it. — Sue

Solution: Sue, it has something to do with either the thermistor of the phone or the USB port circuit in general. But either way, you need to have the USB port replaced because thermistor is also attached to that board. Newer phones would say something like battery temperature is too high or too low instead of showing that icon. Sadly, there’s no other way to fix this but to bring your phone to a service center and have it checked.

#15. Galaxy S2 apps icons grayed out

Problem: Hi, I am using Galaxy S2 since 2 years. Initially I had little problems in over heating of processor. Now few days back my phone got switched off immediately due to over heating and when I switch on the processor I found that the applications which I have installed in it is not working neither opening. Whenever I touch the icon its showing the message “Application is not installed in phone”. After this I tried to restart the phone but even after rebooting its showing the same. The phone is not getting connected to network even if is showing that it is connected to a network. I tried to connect to PC through Samsung Kies but even it isn’t getting detected in kies too. Mainly play store not working too. All the data are present in SD card which needs to be backed up. So what may be the solution for this? I have also shown how the screen looks.

Solution: The screenshot attached to this email showed a lot of app icons grayed out. Basically, when you tap any of those apps, you’ll get the ‘not installed’ error message. Those apps were, of course, installed only that the phone cannot locate files or data needed to run them. Why? Because may be the storage device where those data were stored cannot be detected or read by the phone anymore. So, it is more of an external storage issue than anything else. It could be that the microSD card has totally become corrupt or it was simply un-mounted.

What you can do is to remove the microSD card and boot the phone normally. You’ll still be seeing those grayed out icons because the SD card isn’t connected to the phone. Now, turn the phone off normally and then mount the SD card again and boot the phone. This time, if the phone can detect the SD card, the apps whose icons were grayed out should be fine. If not, then remove your SD card, have your laptop read it and if it can, backup everything that’s in it. After that, format your SD card to FAT32 format and you need to redownload those apps again. Better yet, perform factory reset and bring the phone back to its original settings before re-downloading all your apps.
