Samsung Galaxy S2 Problems and Solutions [Part 1]

galaxy-s2-problems-solutions

I do admit, I was hesitant to write about the Samsung Galaxy S2, which is by the way, so 2011-ish. Considering the popularity of the Galaxy S3, S4 and the upcoming S5, I was thinking no one’s going pick up an S2 anymore. The reality is, dated phones will be shoved aside or be used as backups but aren’t discarded. Sooner or later they will be used again or be sent as gifts, thus, there is still a need to publish support articles.

Problems and Solutions

I already published an article like this last year so every now and then we receive emails from S2 owners. Here are some of them…

#1. Galaxy S2 randomly reboots

Problem 1

Hi, how are you. Please help me with my problem. My phone is Galaxy S2 and I bought it early last year and I didn’t have problems with it until recently when there was an update. Now, my phone reboots at no specific time. Last week, it would reboot about 5 times a day but now it is way more than that already to the point that I could no longer use the phone properly. I’m sure you know how annoying it is when you’re texting and the phone suddenly reboots deleting your message. Do  you have any suggestion on what I should do to fix this problem? Thanks.Genevieve

Problem 2

Hello! I am Zakeen from Pakistan. I have Samsung Galaxy S2 GT I9100. My smartphone is updated to android jellybean 4.1.2. And the problem is that sometimes my phone restart automatically . Second problem is my phone is stilling and screeching like screech on CD or DVD. Please let me know the solution.

Solution

Genevieve, you may need to just clear some data or cache in your phone to bring it back to normal operation. So, for now, I have a couple of things I want you to do for the S2–boot to Safe Mode and wipe cache partition.

Booting to Safe Mode will disable third-party apps that may be causing the problem. You said there was an update prior to the problem so there is a possibility that some apps are incompatible with the new firmware. Here’s how you boot to Safe Mode on the Galaxy S2:

  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, observe the phone closely to see if it would still reboot. If not, then find the apps that may be causing the problem and disable them. However, if the phone still reboots, you need to boot to recovery and wipe the cache partition in preparation for possible Factory Reset. 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 Power button to select.
  7. Highlight reboot system now and press the power button again to reboot.

With the cache partition wiped out, observe the phone again to know whether it would still reboot. If so, there’s no other option but to perform a Factory Reset.

#2. Galaxy S2 won’t take a charge

Problem

Hi! well I’m having a problem with my Samsung Galaxy S2. My phone is draining my battery out, so I bought a new battery. Yet, my phone won’t take the charge. I charge it externally. Is it my phone, do I need a new one?

Answer

It could be your charger. Did you using a different charger, or at least plugged the USB data cable to the back of your desktop computer? There are a lot of possibilities and the first one is the charger. Since you bought a new battery, we’ve already ruled out battery issue. Another thing is the microUSB port of your phone. While the charger is plugged, try to wiggle the cable to see if there is a point when the phone accepts the charge.

But I strongly suggest you plug the cable to your computer because it confirms two things: whether or not your charger is busted, or the cable is broken if the computer couldn’t detect the phone.

#3. Galaxy S2 drains battery rapidly

Problem

Hello, saw your post online about Samsung Galaxy S2. I just got this phone and I flashed a new recovery and KitKat. My battery drains super-rapidly without any reason and the phone gets really hot. The heat problem happened on my HTC Desire with a jellybean from CyanogenMod and I thought it was because the OS was too much for the phone. However the phone still serves well. What do you think the matter is with my S2? Do I flash JB instead? Is it KitKat or something else? And when I checked, my screen consumes the most power….even more than the AndroidOS. Please what can I do?

Answer

Samsung hasn’t released another update since the Android 4.1 Jelly Bean was rolled out for the Galaxy S2 and there is, of course, a reason for that. Actually, I think the problem is the KitKat firmware you flashed but I cannot be sure since you’re using a modified firmware in the first place.

I can tell you’re savvy enough when it comes to flashing ROMs on your phone so you can actually try different ROMs ranging from ICS to JB to KK to know which one causes the fast battery drain. You can also compare the performance of stock firmware with custom ROMs if you like.

#4. Difficulties accessing the network

Problem

Hi, I’ve purchased my S2 two months ago, and I’m having difficulties in accessing network. I have cross above my screen for almost six days, and I tried everything so please I can’t afford to lose my phone and I’m afraid to be a hardware problem. So please I need some help over here, any kind, and let me know of all possible solutions for mi issue. I’m looking forward to hearing from you as soon as possible.

Solution

When I was reading your message, I was hoping you would include or attach a screenshot of your screen just to see what you mean by the “cross.” Without a screenshoot, you left me speculating about this problem. If it were just the usual coverage problem, I would advice you to call your provider because it is more likely a network issue. But since you said there is a “cross above the screen” I would assume it’s the Airplane Mode icon:

  1. From any Home screen, tap the Menu key.
  2. Tap Settings.
  3. Tap More settings.
  4. Tap to select or clear Airplane mode check box to enable or disable wireless services.

But if you meant a circle with a line through it, that’s the spot where coverage signal bars often sit. It means it’s turned off or still searching for network. It could be that you’re in the area where there is no service coverage or have selected a different Network Mode. Try these steps:

  1. With the phone still on, remove the battery.
  2. Without the battery press the phone’s Power button and hold it for 30 seconds.
  3. Place the battery back and turn the phone back on.
  4. Wait until the phone successfully detected signal from the network.

It would take a minute or two for the phone to completely get service but if it still can’t, try these:

From the home screen, tap the Menu key.

  1. Tap Settings.
  2. Tap More settings.
  3. Tap Mobile networks.
  4. Tap Network Mode.
  5. Tap to select one of the following: GSM/WCDMA (Auto mode), GSM Only, WCDMA only.

I don’t know the preferred network mode in your area so I suggest you try one after another.

#5. Galaxy S2 freezes when Wi-Fi is enabled

Problem

Hi, I have an unlocked AT&T Samsung Galaxy S2 . Worked great for a year and a half, then, this one time i was travelling to another city and wanted internet on my laptop, so installed this app that was suggested by some guy on YouTube, which could make my phone work like a modem/router and provide WiFi signal to let my laptop connect to the internet through my cellphone network. I am guessing that’s when  this problem started. I have, since, deleted that app.

Now, the problem is , my phone goes crazy when I connect to any wi-fi network. It could be my home wi-fi network, office, at a friends place, anywhere . These are the series of events that usually happens :

1)   It connects momentarily and lets me get my whatsapp msgs, connects to facebook, browse the net etc , but within minutes disconnects. Then, the power button does not respond ( if the phone is not locked, then it wouldn’t lock if i press the power button and if its locked, then it wouldn’t illuminate the screen for me to unlock it . But if I insert the charger cable, the screen illuminates and it indicates that phone is charging and lets me unlock the phone!)

2)  Next, when i try to go to settings and try to turn off the wifi , so that I could atleast use the mobile data, it acts all hung up and slow. I am able to open Settings, then Wireless and Network, but when I click on WiFi Settings, it just freezes . After a minute or so, I get an error message saying settings is not responding and gives me the options to force close or wait .

After this I will have to reboot the phone and then quickly, before it again tries to connect to the wifi, go to Settings and disable WiFi . Once disabled, it is again a perfect phone. Connects to the mobile network data and operates without a glitch. (I have used this phone in India with AIRTEL, have been using it here in the US with Lycamobile). Thanks for listening, I really hope you have a solutions for this. Thanks in advance.Regards, Chirag

Solution

Whatever the name of the application is, it’s clear as the day that it’s the one causing the problem. So, if I were you, I would uninstall the app without hesitation just to bring the phone back to its normal operating performance. I understand there’s always time when you need to share your internet connection to your other devices but if  your carrier didn’t include Mobile Tethering or Hotspot in your device, it is more likely they don’t allow it. Yes, there are actually thousands of useful videos on YouTube you could follow, or apps you can install but the one you have right now is just not it. Here’s how you uninstall apps from your phone:

  1. From any Home screen, tap the Menu key.
  2. Tap Settings.
  3. Tap the Applications manager.
  4. Locate and tap the application you want to delete or uninstall.
  5. Tap Uninstall.
  6. Tap OK .
  7. Tap OK again to confirm.

I’m not sure if you’ve already checked your phone for possible mobile hotspot feature but Galaxy S2 is supposed to have that. Try this:

  1. From any Home screen, tap the Menu key.
  2. Tap Settings.
  3. Tap More Settings.
  4. Tap Tethering and Mobile HotSpot.
  5. Tap the Mobile Hotspot Switch.
  6. If there exists Mobile Hotspot feature on your phone, you need to configure it the first time you use it.

I just hope you have this feature on your phone so that you’ll refrain from using third-party applications that could potentially damage the poor thing.

Problems and Solutions

#1. Messaging has stopped working

Problem

Hi there, my Samsung Galaxy S2 phone has been working fine ’til last night. I have been experiencing difficulty with MESSAGES!! When I try and open up a message, a message pop-up saying “unfortunately, messaging has stopped working”. I have tried restarting my phone several times, and the same message pops-up! Please help me out, as I need to txt important things out. Thanks.Anna

Solution

Anna, it could be just a minor glitch on the Messaging app. Here’s a simple procedure that could help you fix this problem:

  1. From any Home screen, tap the Menu key.
  2. Choose Settings.
  3. Tap the Applications manager.
  4. Scroll to and tap Messaging.
  5. Touch Clear Cache.
  6. Touch Clear Data (please note you may lose your messaging settings when you do this).
  7. Tap OK.

Now, reboot the phone and observe if the Messaging app still crashes.

#2. Cannot unlock Galaxy S2

Problem

I have a t mobile galaxy s2 and an s4. Both devices have bad reception and a super slow network. To resolve these issues, I asked t mobile to give me network SIM unlock codes for both devices. They gave me the codes. The code for my s4 worked with no problems and I replaced the SIM card with one from AT&T. Problem solved.  On the other hand, the code for my S2 didn’t work. I confirmed the code was accurate with two other companies. It appears to be a problem with the device.  Any advice you can give me on this issue would be greatly appreciated.  It just keeps saying network unlock unsuccessful. Sincerely and respectfully, Zuri.

Solution

Find your phone’s IMEI; you can find it by removing the battery or going to Settings > About phone > Status. Now call your service provider and confirm they have the correct IMEI on their file. Note that the unlock code is based on the IMEI of the phone.

The last time I had my phone unlocked, I employed the services of cellunlocker.net where I purchased the unlock code that, of course, worked at first try. If, however, your phone was frozen after several tries of entering  the code, you may want to get unfreeze code from here: Samsung IMEI Unfreeze Codes.

#3. Cannot download MMS pictures

Problem

I have 2 questions, First my Galaxy S2 wont download or open pics anymore from text messaging.  I can send a pic to myself okay but cant receive from anyone else which I could for the first 8 months of service.   Also I have tried to find a phone case that wont cause feedback to incoming callers.  Works fine without case, but have tried several different cases with same result.  I really like the phone, but it sure has its share of problems.  It is an AT&T with SIM card but used on Straight Talk.

Solution

As to problems, yes, you can always expect them because these devices are far from being perfect. But when it comes to an MMS sending / receiving issues, there is a possibility that the APN settings were messed up or Straight Talk may have changed its settings again. The last time I check, the APN settings that works are the following:

  • NAME: STRAIGHT_TALK
  • APN: tfdata
  • MMSC: https://mms-tf.net
  • MMS PROXY: mms3.tracfone.com
  • MMS PORT: 80

Try to open the APN settings on your device and confirm that they’re the same as the one I posted above. If, however, you have the correct APN but you still can’t receive MMS from others, please Straight Talk because I’m sure they always have better answers than I am when it comes to network problems.

As to the best cases for your Samsung Galaxy S2, try Seidio’s lineups; they seem to have really solid products.

#4. Galaxy S2 shows it charges even if not plugged in

Problem

Hi there, I hope you can help with my Samsung Galaxy S2, it’s been acting a bit weird for the past few days now, randomly charging on its own when its not plugged in, and when it is connected and charging, the screen goes funny, lines move up and down it, like an old TV.

Now its started turning itself off and resetting the time and date every time I turn it back on. It just randomly died on me, switched itself off, then turned itself back on again, but as soon as I went to do something on it, it turned itself off again and now won’t turn back on. Have had to take the battery out, as after putting it on charge for a little while, its still doing nothing. Thanks.Laura

Solution

I have a feeling that your phone has been submerged on water or has some kind of liquid damage. If not, it may have been dropped and the impact messed up components inside. But either way, or whatever the cause of the problem is, you need to have the phone checked by an authorized technician. I’m afraid it’s not about the phone’s software but hardware.

#5. Galaxy S2 opens another window

Problem

Hi, for some reason it seems that cooler temperatures causes my phone to jump to different screens.  For example I might begin to start an email message and the menu settings will jump up or l might begin a search on Google and it will jump to another location. Ever heard of this before?  Any help would be greatly appreciated. Thanks, Lonnie.

Solution

If you’re using a third-party case, try to remove it and observe if the phone still acts the same. I’m sure there is a valid reason why the phone is acting like this but I’m certain it’s not the temperature. Another thing, please try to boot the phone to Safe Mode and see if it still happens because I think an app is causing this issue. When in Safe Mode and the phone still manifests the issue, Factory Reset may be necessary.

#6. Galaxy S2 screen turns on and off

Problem

So I have this issue with my galaxy s2. I will leave it on a surface, having the screen turned off. and usually around once every 10 minutes the screen will pop on and then pop back off.   I’ve received no messages no alarms buzzers etc. The screen just comes on and then turns off.  It’s kind of freaky and annoying and probably happens while it’s in my pocket, although obviously I can’t see it then.  Thanks.Brandon

Solution

Brandon, there’s an app or a service that’s causing the phone to act like this. The first troubleshooting step you should do is to boot the Galaxy S2 to Safe Mode and observe if it still happens. If it does not, then it is a third-party app that’s causing it. However, if the screen still automatically turns on then off even in Safe Mode, then one of the pre-installed apps or core services is causing the problem. Either way, if you don’t want to perform factory reset, download and install Wakelock Detector for you to know which app wakes your phone up. The app comes the most recommended app for this kind of issue.

#7. Galaxy S2 drains battery faster

Problem

Hi, I have a Samsung S2 I9100, right now I have updated it to 4.1.2 and always keep cleaning its cache for better performance but it keeps draining the battery very fast and heats up during charging and some times get very slow despite cleaning cache regularly. Please help me out. Regards, Abbas.

Solution

There could be a lot of factors that contribute to the fast draining of the battery and you need to find those. Of course, start with the third-party apps. Boot to safe mode to stop all third-party apps then mind of how long the battery could last. Of course, it will take hours to complete but it’s for the sake of knowing what causes the fast draining of the battery and to prevent further inconvenience of charging the phone every few hours.

If the battery lasts longer when in safe mode (of course, there should be a significant difference) then find the app that’s causing the draining. Otherwise, boot normally and enable Power Saving Mode just to rule out the possibility that your phone’s CPU is always on the overdrive or the screen was set to the highest level. You also need to turn off haptic feedback.

If your phone frequently gets disconnected from the mobile data network, it could also cause fast draining because the phone will keep searching and reconnecting every minute. So, the radio hardware and the CPU are always working. I’m sure you know some tricks on how to maximize the juice and if all those procedures fail, then you must consider buying a new battery.

#8. Galaxy S2 with cracked screen

Problem

Hi, glass etc slightly fractured and although phone does work (it will ring) LCD no longer does. As advised, it is swipe pattern protected but as a result I can’t unlock it because of LCD fault (I do remember pattern).  O2 Guru suggested connecting via Kies as this would bypass swipe security, it didn’t.

Another suggestion was to buy b/tooth mouse and MHL/HDMI , connect phone to TV thus using that screen, apparently this works on all phones…except S2, Different encryption it seems. So, any ideas how I might retrieve data remaining on the phone? Many thanks, Tom.

Solution

There’s only so much we can do for a phone whose screen is broken. KIES can only access phones that are already unlocked, so the swipe pattern is the only hindrance to retrieve some data. There is another thing you could; use Samsung’s Find My Mobile service that would allow you to unlock your phone provided that your phone is connected to the internet. If you could unlock the phone using Find My Mobile, then you can use KIES to retrieve your data, otherwise, you have one last option below.

If the phone’s display still lights up and display picture normally, the digitizer could have been the only component that was fractured. Just a little info, all touchscreen phones have display panels and digitizers. The former displays the picture while the latter conducts touch commands. Between the two, the digitizer is often the first one to get damaged during impacts simply because it is the outer layer and way thinner than the display panel.

If only the digitizer was broken, then you could buy a replacement and use your phone again. If  you want, you can install it yourself or you can employ the help of an authorized technician. Other than the two procedures I mentioned here, there’s no other ways proven to get the job done.

#9. Talkback can’t be disabled on Galaxy S2

Problem

After upgrading the OS by OTA from ICS 4.0.4 to JB 4.1.2, my S2 will read out ‘page 1 of 7, page 2 of 7’ and so on as I swipe the screen, or ‘folder open’ and ‘folder closed’ which is most annoying, to say the least. I had set Talk Back to OFF to no avail. To get rid of the talk back, I had to disable Google-Text-to-Speech. The S2 didn’t give this problem when running ICS 4.0.4 and I am unable to revert to previous version. Can you please advise. Thank you.Yap

Solution

There could be an app that also uses Talkback’s services. It’s always been like this when it comes to Talkback problems–the service has already been disabled but the phone still reads aloud every action you do on the phone as well as the pages on the screen. Lightflow was one of the apps that could trigger this problem. In case you don’t know which app causes it, try booting the phone to Safe Mode and observe if it still talks back. If not, then a third-party app should be found to stop this.

If the phone still reads aloud every word on the screen even when in Safe Mode, then it is necessary to perform factory reset but before you actually do that, try wiping the cache partition first.

#10. Galaxy S2 won’t turn on

Problem

Good morning I wonder if you can help.  My Galaxy S2 won’t turn on when I press the power button, is there a way round this. I do have insurance on it but have to pay the excess, I’m not due to upgrade yet. Love the phone. Hope you can help.Jacqui

Solution

First of all, make sure your phone’s battery has power; plug the charger in and let the phone charge. While the phone is charging, look at the screen and see if there’s a charging icon–the one used to see. If there is, then perhaps there’s no problem with the phone, just a drained battery. If there’s none, try to wiggle the cable or make sure the cable fits well on the phone’s microUSB port. There is a possibility that the phone has drained its battery completely but your charger is busted.

I would also recommend you press and hold the power button to see if the phone responds to that. If all else fails, then use your insurance. After all, that’s the purpose of it.
