 Galaxy S2 Charging Issue

Problem: Hi, I’ve been having a problem recently with my Samsung Galaxy SII. Let me start off by saying I use it with Boost Mobile and got it officially refurbished from the Boost website. And I’ve had it for about six month or more. So my original battery wasn’t lasting as long as it used to (I suppose ‘battery memory effect’ played a part) and I bought two spare batteries and an external charger. I’ve had the 3 batteries (original which still gets decent time, and the two new) for about 2-3 weeks. But now, within the last 3 days, any time I go to change out the batteries, even though the phone is never plugged in anymore, the icon with the battery charging shows up. Then, when I go to turn the phone on, the small battery icon in the upper corner flashes a lightning bolt symbol and the makes a ‘ping-pong’ sound, and the lock screen indicates it’s charging. But as soon as the words “charging” followed by the percentage pops up, it disappears. For some reason it’s acting like it’s charging one second by then fine the next. Even in the settings menu under “battery status” the words were flickering between “discharging” and “charging”. This has become very annoying and to the point where switching between charging and not seems to kill the battery even faster (I would assume because not only is the phone not locking because it feels the need to light up and indicate when it’s “charging”, but also because the back and forth would waste power).

Solution: What we need to do first if determine if it is a software or a hardware issue. To check if it is a software issue try booting your device in safe mode. During this mode the S2 will not load any third-party apps that you have installed.

  • 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 goes away in safe mode then an app is causing it. Try uninstalling apps that you have installed.

If the problem still occurs then this could already be a hardware issue. This may be caused by a dirty or faulty microUSB port.

Try cleaning the charging port with cotton and alcohol. Make sure to remove your battery first. If this doesn’t work then you may want to bring your device to an authorized service center to have it checked.

Galaxy S2 Power Button Issue

Problem: I would like to see if you know why the problem with my phone is occuring. I have a Samsung Galaxy S2. The power button recently became hyper sensitive where just sliding my finger along the side of the phone would turn it on, if the power off-restart menu etc came on by itself it means I would only have about 3 seconds before my phone restarted itself and almost everytime I try to download an app off wifi or my data plan it gives me error code 919. Any help is appreciated.

Solution: It looks like this is already a hardware issue concerning the power button itself. Aside from having it fixed at an authorized service center you could try getting a rubber case for your device. This will make the power button less sensitive while also giving your device a certain degree of protection.

Galaxy S2 Vibrates When Taking Picture

Problem: Please the version of my samsung galaxy s2 2.3.6 anytime i want to take a camera picture the phone starts  vibrating small and when you touch the screen it stops. Aside dat it heats when the camera is turn on for a long time. Please what should i do

Solution: This issue is most likely a hardware related issue. However we also can’t rule out the software causing it. Since it is easier to check if a software is causing it then this is what we will be doing first. Try to 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.

In Safe mode try taking a picture and see if your device still vibrates. If it doesn’t then you may want to uninstall some of the apps in your device since it may be causing the problem.

If the issue still persists then this is already a hardware related issue that’s most likely caused by the focusing mechanism of the camera. You will need to have this checked at an authorized service center.

Galaxy S2 Display Issues

Problem: Hi .. I seem to have a problem with the backlight on my screen everything is awful dark and when I turn the brightness up full everything is for too bright and whitish .. is my screen and phone knackered

Solution: This isn’t normal for a Galaxy S2. It looks like there may be a problem with the display of the device itself. Have this checked at an authorized service center as this may need to be replaced.

Galaxy S2 Waze Glitch

Problem: Hello, Waze is installed in my galaxy s2 for about 1.5 years. Recently when I enter the app, the screen starts to flicker for an unknown period of time (sometimes a few seconds sometimes indefinitely). I tried uninstalling and reinstalling numerous time, to no avail. I took the phone to a phone technician who claimed that he never saw such a phenomenon and was a loss to help. Perhaps you have a suggestion, thank you in advance.

Solution: This might not be a problem caused by the Waze app but from other apps that are interfering with it. To check on this you will need to do a factory reset on your device then install only the Waze app. Before doing the factory reset make sure that you backup of all your important data first.

  • 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

Now that the S2 is in its initial factory condition download the Waze app from the google Play Store and see if the problem still occurs.

Galaxy S2 Does Not Boot

Problem: My galaxy s2 totally crashed when I try to turn it on all it does is bring up the Samsung galaxy words the it slowly flashes on off on off can not shut it down without battery removal. I tried te factory reset get the menu said to factory reboot but all it does is flash.    any help would be appreciated.

Solution: While your S2 is still on remove its battery. Press on the power button for at least 10 seconds then place back the battery. This removes any residual power on the device and clears out its memory. Try turning your device on and see if it boots normally. If it can’t then try to do a factory reset once again if you are able to.

If the device doesn’t allow you to perform a factory reset then you may have to bring this to an authorized service center to have it checked.

Galaxy S2 Wi-Fi Keeps Turning On Automatically

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.

Solution: Try to check on your Wi-Fi settings and uncheck “Always allow scanning” under the advanced settings. If this doesn’t resolve the issue then it’s likely that an app is causing your Wi-Fi to turn on. Try booting your device into safe mode and observe if your Wi-Fi gets activated.

  • 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 it doesn’t get activated then you will need to do a trial and error method by uninstalling the apps on your device and see which one is causing the issue.

Galaxy S2 Does Not Connect To PC

Problem: Every time I plug in my Galaxy S2 it makes the windows “you plugged in a device” little dinging sound, and then a half second later it disconnects and makes the same dinging disconnect sound. It does this with every computer I have plugged it into. I think it has to be something on the phone, but the phone charges just fine so I don’t think it is the charge port. Any ideas? Heard of this before? Thanks!

Solution: Have you checked if the drivers for your S2 are installed properly in your computers? If they are installed properly then it could be an issue with the phone itself or the USB cord. Try using another USB cord and see if this does the trick. You can also try booting your device in safe mode then connecting it to your computer to see if an app is causing this problem.

Galaxy S2 Charging Issues

Problem: I have had this phone about 2 years, no real issues with charging. All of a sudden the chargers are draining my battery really quick instead of charging, from about 50% to 0% in about 10 minutes. I use different chargers whenever I am at work, home, car as I always have. Now all that seems to charge my phone at all is my Samsung charger that came with the phone, or a USB to the computer. And will only charge at all if I have the phone in power saving mode. Any thoughts?

Solution: It looks like you might have a faulty battery. Have you tried using a new Samsung battery and see if the problem still happens?

Galaxy S2 Not Reading SD Cards

Problem: My galaxy s2 isn’t reading ANY sd cards. I’ve tried a few different ones, but it’s not reading any of them. I’ve tried the same cards in a different phone and they work fine. Anyone had this happen? What did you do?

Solution: Try to reformat your SD card first using the FAT32 file system in your PC and then try placing it in your S2. If your phone still can’t read the SD card then the microSD card connector on your phone may be dirty. Turn off your device, take out its battery, and then try cleaning the connector with alcohol and cotton. Now check and see if the SD card can be read. If not then you may need to bring your S2 to an authorized service center as the SD card connector on the device may be misaligned.
