Galaxy S2 Call Screen Vanishes

Problem: Hi, I have found an issue (which is maddening) when I make a phonecall.  It may be during a call, at the end of a call when one wants to end it or when leaving a voicemail message, the phone call screen suddenly vanishes and then the only way I have found to terminate the call is to restart the phone.  It is a real nuisance and design flaw!  Any suggestions, please?

Solution: This could be a hardware issue concerning the proximity sensor of the device. Under normal conditions the proximity sensor turns off the display when the device is close to your ear since you won’t really need to see the display. This improves the battery life of the device. Once the phone is away from your ears the display should immediately light up. To test if this is the case try disabling it first.

  • Go to Phone dialer
  • Press Menu button
  • Tap call Settings
  • Scroll down and look for “Turn off screen during calls”
  • Uncheck it
  • Now the proximity sensor it turned off during calls on your phone.

Try to have someone call your phone and see if the display still goes black. With the proximity sensor turned off your display should not go blank. If the issue is gone then you may leave the proximity sensor setting unchecked which is a temporary solution. A more permanent solution would be to replace the proximity sensor of your device which can be done at an authorized service center.

Galaxy S2 Does Not Turn On

Problem: Helllo! I really need some help on how to turn on my Samsung Galaxy S2 phone, which I have now owned for 3 years now. I finally did the firmware update last night and this morning when I checked my phone, it asked for another update to install. So yes, I agreed to install thinking it was part of last nights updates. Straight after that, it said it will reboot itself – but failed. Now I’m trying so very hard to reboot my phone. Looking up troubleshooting websites but all methods fail with my phone. Is there anything else I can do? I don’t want to loose all my personal photos and stuff… I didn’t get the chance to backup everything on my laptop :'(. I’m slapping myself on the forehead thinking this wouldn’ of happened! I know its been a while that I have owned this phone but I have taken care of it so good. Could you help me out? Your help will be very much appreciated!

Solution: Try taking out the battery then press the power button for at least 10 seconds. Now replace the battery and turn on your device. In most cases this procedure should boot up your device. If your phone still does not turn on then try plugging it into a computer with the latest Kies software installed. Use a USB cord that is known to work. Try turning it on and see if it gets recognized.

One other reason why your phone will not reboot is that perhaps the battery does not have enough charge.

  • Connect your Samsung Galaxy S II to the charger that came with it.
  • While charging, verify that the charging indicator displays.

For a fully drained battery it may take a couple of minutes for the charging indicator to show up. If it does not show up then you might want to try using another battery on your device.

Galaxy S2 Resets On Its Own

Problem: Hello, I recently replaced the battery in my Samsung S2 mobile. I fully charged the phone before the night, when I wake up the phone is already out of battery. After fully charging the phone again I am always asked to choose the language settings and to set the time and date, and the contacts that I put are gone. Please let me know what suggestions you have to solve these problems. Thank You

Solution: This could be a battery issue. Since the problem started when you replaced the battery try using another battery and see if the problem disappears. When a battery doesn’t have any charge it’s just like having no battery on the phone. Once you place a battery with some charge on it you will notice that you would have to set the time and date as well as the language. What’s puzzling me though is that your contacts have also disappeared. Anyway, try using a fresh battery first as I suspect this is the main cause of the problem.

Galaxy S2 Menu Problem

Problem: Three of the five phones I have had have had this problem to verying degrees. When I got this last phone, as the phone was starting up before installing any new programs, I could hear the hypatic feedback coming from the phone, feels like the phone keeps giving off little kicks. and this is what happens when the menu button starts popping up and down by itself. It is now even going into programs in addition to just jumping up and down. in other words, it’s as if I have hit the menu button and opened an app but I am just sitting there watching it do this. When I stop laughing, it can sometimes be annoying…anyway, wondering if it could be something besides apps loaded. It started happening even before I did anything to the phone, though not quite as bad as the last phone I just returned.

Solution: It appears to be a hardware problem. The home button of your device could already be worn out causing this to happen. You might want to bring your device to an authorized service center to have the home button replaced. Just to cover all bases you could also try doing a factory reset on your device to rule out any software issues causing the problem. You will have to backup your data first before performing this procedure.

  • Turn the phone off
  • With the phone still off, hold down the Power, Volume Up and Menu buttons at the same time for about 10 seconds. Release them when you see the green android logo. This’ll get you into the unlock/reset menu
  • Scroll down and select ‘Wipe Data/Factory Reset’. You can use the volume buttons to scroll up/down and the power button to confirm selections.
  • Select ‘Yes – Delete All User Data’.
  • Select ‘Reboot System Now’. The phone then reboots to factory settings with the security lock removed.

If your device works normally after the factory reset then there is no need for it to be sent to a service center.

Galaxy S2 Does Not Turn On

Problem: Hi, having some issues with my galaxy s2, woke up this morning to it vibrating so I took out the battery and left it alone for a bit, put the battery back in later and wouldn’t turn on, it doesn’t vibrate like it should prior to turning on so I put it to charge some time later and the battery symbol will come on and eventually just get a bit brighter than normal for about a second and then fades, tried a soft reset, did nothing, took out the battery and plugged it into my laptop and all it did was vibrate continuously, Pretty sure it’s not a power button issue because I had that replaced recently and the symptoms are different, please help.

Solution: Try taking out the battery then press the power button for 5 seconds, re-insert the battery. See if you can turn on your device normally. If you are still experiencing the same problem then leave battery out for 10-15 minutes and re-insert. If that does not seem to work then one other culprit could be a fault power button. Since you say that it has recently been replaced try having it checked again. It might not be correctly connected to the board or it could have gone faulty.

Galaxy S2 Not Enough Space Issue On Gallery App

Problem: Dear Droid guy, I have read your pages on galaxy s2 problems and solutions and several other forums, websites and blogs but i can’t fix this particular probem. The problem is whenever i try to open my gallery i get this error message “Not Enough space. Delete Unnecessary items, such as downloaded software, pictures, videos and documents” I have cleared the cache and i have also used clean master to delete log files. I have also deleted the dumpstack. I’m running android 4.1.2 jellybean. Please help!

Solution: First check and see if there are any latest updates for the software of your device. Update your device if there is any. The latest updates usually comes with several fixes and improvements that can solve certain issues that a device is facing.

Next you might want to clear the system cache of your device. This does not delete any of your personal information.

  • Turn off the phone.
  • Remove the battery and Reinsert it.
  • Hold the Volume Up and Volume Down keys.
  • Press and hold the Power key while continuing to hold both volume keys.
  • Release the keys when the Samsung logo appears on the screen.
  • Press the Volume Down key to scroll to delete all cache data.
  • Press the Home to select it.
  • Wait for a few seconds and the phone clears information.
  • Press the Home to select reboot system now.
  • Wait as the phone restarts.

Now check and see if the problem still occurs by opening your Gallery app.

To verify that it is not a third party app that is causing this problem you can boot your device in Safe Mode.

  • Power off the device.
  • Press and hold the Power/Lock key for one or two seconds to turn on the device.
  • When the Samsung logo displays, press and hold the Volume down key until the lock screen displays.
  • When the Lock screen is displayed, Safe mode is displayed in the lower-left corner of the screen. To exit Safe mode, restart your device.

If in Safe Mode the error message does not pop-up then this issue is most likely caused by a third party app. Boot your device normally then find the particular app and uninstall it.

Galaxy S2 Home Key Randomly Activates

Problem: I am currently experiencing wirh the home key popping as if i touched it. Sometimes just being close to the phone it happens. If seems like i have a ghost in the phone or a virus. I have done a factory reset and i still habe the problems. If I’m playing a game it does not happen. If its on or im on the internet it pops up. Are there any fix it to rhis problem. Its driving me crazy. Especially since i love this phone.

Solution: There’s a huge possibility that your home button is already faulty and needs to be replaced. Since you mentioned that you already performed a factory reset on your device this rules out the possibility that an app or the phone software is causing this. Try bringing your device to an authorized service center and have the home button replaced.

Galaxy S2 Wi-Fi Randomly Turns On

Problem: My wifi keeps turning itself on an completely draining my battery. It’s the worst when I’m in an area when no wifi is available since it just keeps looking for it and drains the battery even faster. I’ve looked through many forums and haven’t found anything that works yet. The only options I’ve heard have been for other service providers. “Connection Optimizer” or “Smart WiFi” don’t exist on my phone. I’m now with a new service provider but I bought my phone from T-Mobile and the problem started before I switched. It’s a UK phone, incase that makes any difference. Any ideas on how I can fix it without having to reset my phone?

Solution: This could just be an issue with your Wi-Fi settings. In the system settings under Wireless and Network> Wi-Fi settings, make sure Auto connect isn’t selected. After this do a soft reset on your device. Turn your phone off. Take out the battery for 30 seconds while holding the power button. Replace the battery then turn your device on. Check and see if the problem still occurs.

If your Wi-Fi is still randomly turning on then it could be an app that is causing this. Try booting your device in Safe Mode.

  • Power off the device.
  • Press and hold the Power/Lock key for one or two seconds to turn on the device.
  • When the Samsung logo displays, press and hold the Volume down key until the lock screen displays.
  • When the Lock screen is displayed, Safe mode is displayed in the lower-left corner of the screen. To exit Safe mode, restart your device.

Observe your device in Safe Mode and see if the Wi-Fi turns on. If not then you might need to find and uninstall the third party app that is causing this.

Galaxy S2 Freezes While Charging

Problem: Sometimes while my Galaxy S2 (charging (wall charge or usb – doesn’t matter) and i try to unlock it – it doesn’t respond or light up at all. I tried to call myself to see if it wakes but it doesn’t do absolutely nothing – not even a “blink” or sound. I have to hold up power button until it reboots to fix it. After I force reboot it – the battery seems charged up as normal. This issue occurs at random and only while it’s charging, so i don’t really know what causes it. I’m using the same charger/cable as always. I don’t have bumps on my battery either. It looks like it freezes while sleeping so it needs force restart. What do you suggest me to do?

Solution: Try using a different wall charger and see if the problem still occurs. Also, try to boot your device in Safe Mode while charging.

  • Power off the device.
  • Press and hold the Power/Lock key for one or two seconds to turn on the device.
  • When the Samsung logo displays, press and hold the Volume down key until the lock screen displays.
  • When the Lock screen is displayed, Safe mode is displayed in the lower-left corner of the screen. To exit Safe mode, restart your device.

If the problem does not occur while in Safe Mode then there is a third party app that is causing this. Try to find it and uninstall it.

Galaxy S2 No Service

Problem: My gf recently gave me her galaxy s2 the phone was working fine when she had it except the charging port wasnt working so she had it fixed. Now it keeps saying theres no service…theres no bars and a circle at the top with a line thru it.There was data the other day for a little while but its not working now. Boost mobile has updated everything and reset it.whats wrong with it?

Solution: Try using another SIM on the device and see if it works. The current SIM you are using might not be recognized by your phone. If the new SIM does not work then turn off your device and take out the battery. Check the SIM contacts on your device and see if there are any dirt or misalignments. If you see any dirt just use a cotton dipped in alcohol to clean it. If you can spot some misalignment in the contacts then you might want to bring your device to an authorized service center to have it fixed.

Try to check your IMEI by going to Settings – About Device – Status – IMEI. If it says “Unknown” then this is most likely the cause of your problem. Most of the time this can be resolved by a factory reset. Make sure to backup all of your important data first.

  • Turn off the phone.
  • Remove the battery and Reinsert it.
  • Hold the Volume Up and Volume Down keys.
  • Press and hold the Power key while continuing to hold both volume keys.
  • Release the keys when the Samsung logo appears on the screen.
  • Press the Volume Down key to scroll to delete all cache data.
  • Press the Home to select it.
  • Wait for a few seconds and the phone clears information.
  • Press the Home to select reboot system now.
  • Wait as the phone restarts.

Galaxy S2 USB Device Not Recognized

Problem: I charge my phone via usb cable directly onto my computer sometimes, and every now and then I get a “USB device not recognized” error message. It is hit and miss, and I’m not exactly sure why. Does anyone have the same thing happen to them?

Solution: The USB cord you are using might be faulty. Try using a different USB cord and see if the error message still appears. If it does then the problem may be in your computer USB port or the USB port of your device. Try connecting your device to a different USB port in your computer. If the error message still occurs then the problem is with your phone USB port. Try cleaning the USN port of your phone as it may only be dirt that is causing this. If it is clean then one temporary fix to this is to find the specific position so that the error message does not pop up when you are charging your phone. A more permanent fix is to have the USB port of your device replaced at an authorized service center.
