S3 Turns Off When Different Charger Used

Problem: Hi there. I bought a used samsung galaxy s3 about 4 months ago now, in perfect working and cosmetic order and has been running fine for the whole time but today I have been using my phone with a different charger and my phones speakers start crackling then different coloured lines go across the screen then everything freezes and I have to take out my battery, (the inside of my phone was really hot) then it won’t turn back on because all the battery has gone so have to charge it up again. Hope you can help with this strange problem I have never experienced before or can suggest a way to get it fixed, many thanks.

Solution: If this issue started when you used a different charger then the charger may be the cause of the problem. Try using your old charger or if it is defective get another Samsung wall charger.

You should also check your phone charging port if there are any signs of dirt or lint. Clean it if necessary using a toothpick or cotton bud dipped in alcohol.

Try also to replace the USB cord you use in charging the phone as this may be faulty.

S3 Battery Disconnected Error

Problem: I would be very grateful if you please send me your opinion regarding a problem i have with my galaxy s3. Occasionally it is a quite difficult to charge the battery and there is an indication on the screen saying “battery disconnected “. If this is helpful I have changed my battery with a new one while it was destroyed and I’m using a konpson battery 3.7 v with higher capacity 4450mAh. I have to say that this problem began when one day while I was using the phone running, some sweat went into the device. At the beginning the device did not have any response at all with the above indication but the next day started working properly again. However sometimes I have this problem especially when i switch off the device for a few hours. If there is anything i can do please let me know ASAP. Thanks a lot in advance.

Solution: There are different factors to consider as to why this issue is happening. The first thing you should consider is that there may be an intermittent connection between the battery and the phone. If this is the case then you should take out the battery and using an eraser or cotton bud dipped in alcohol clean the gold contacts of the battery as well as that of the phone.

If the issue persists then next thing you should concentrate on is the battery itself. Try replacing it with a new one and see if the problem still occurs.

Finally, if all else fails then there’s also the possibility that this may be software related. Check if there are any new software updates available for your phone. I also suggest that you backup your phone data and do a factory reset.

  • Turn off the device.
  • Press and hold the following three buttons at the same time: Volume Up key, Home key, Power key.
  • When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  • When the Android System Recovery screen appears, release the Volume Up and Home keys.
  • Press the Volume down key to highlight ‘wipe data / factory reset.’
  • Press Power button to select.
  • Press the Volume down key to highlight ‘delete all user data.’
  • Press Power button to select and start the master reset. When the master reset is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to turn the restart the device.

S3 Turns Off When Battery Reaches 20%

Problem: I have Samsung Galaxy s3 and when the battery reaches 20% the screen starts flashing and the phone turns off and won’t go on until I put it on charger.

Solution: In this case you need to isolate the problem if it is caused by either the phone software or hardware.

The first thing you need to do is to backup your phone data and do a factory reset.

  • Turn off the device.
  • Press and hold the following three buttons at the same time: Volume Up key, Home key, Power key.
  • When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  • When the Android System Recovery screen appears, release the Volume Up and Home keys.
  • Press the Volume down key to highlight ‘wipe data / factory reset.’
  • Press Power button to select.
  • Press the Volume down key to highlight ‘delete all user data.’
  • Press Power button to select and start the master reset. When the master reset is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to turn the restart the device.

If the problem still persists after the factory reset then this is most likely a hardware issue. If this is the case then try getting a new battery for your phone.

S3 Does Not Turn On When Battery Drains

Problem: I recently started having problems with my Galaxy s3. When I turn it off, or it runs out of battery, it doesn’t seem to want to charge or turn back on. Every 10 seconds it vibrates for 1 second. When it is on, it keeps popping up the menu for power off/airplane mode/restart. And it goes to the home screen constantly. I have did the soft reset. Kind of don’t want to do the hard reset unless I am sure it’s worth the time. I have my data backed up to a 8gb sd card. Seems to be getting worse and worse? Thank you in advance for your time and assistance.

Solution: In cases like this the most likely cause is that the phone battery is already too weak.If your phone battery charges very slowly or discharges quickly then I suggest getting a new battery first then check if the issue gets resolved.

S3 “Unable to charge your device” Error

Problem: I am receiving an error message when I attempt to charge my Samsung Galaxy s3 that reads “Unable to charge your device. Make sure that you are using a Samsung-compatible battery and charger, and that your device is properly connected to the charger.” This issue just started today. I am using the charger that came with my phone when I originally purchased it and am using the same battery that came with the phone. It charged briefly earlier today but not long enough to receive a full charge. Is there anything I can do to save the phone or is it time for a new one?

Solution: If you are still using the original charger and battery of your phone then the first step that you should do is to clean the charging port of your phone. Use a cotton bud dipped in alcohol or a toothpick in cleaning the dirt or lint that may be present in the charging port.

Check if the issue still persists. If it does then try to replace the USB cord that your wall charger is using. Sometimes if the USB cord is faulty you will get this type of error message.

Finally, there are also cases when this error message is caused by a glitch in the phone software. If this is the case then you should back up your phone data then proceed with a factory reset.

  • Turn off the device.
  • Press and hold the following three buttons at the same time: Volume Up key, Home key, Power key.
  • When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  • When the Android System Recovery screen appears, release the Volume Up and Home keys.
  • Press the Volume down key to highlight ‘wipe data / factory reset.’
  • Press Power button to select.
  • Press the Volume down key to highlight ‘delete all user data.’
  • Press Power button to select and start the master reset. When the master reset is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to turn the restart the device.

S3 “Connect to dock” Error

Problem: Hi, I bought a new power bank a week ago. It won’t charge my Galaxy S3. I get a “Connected to dock” message and tone, then nothing happens. Once in a while it starts to charge and then stops immediately. I charged the power bank several times and  once overnight. All indicator lights are on.  I use the USB cable that came it per eBay seller and have tried both ports 1A and 2.1A. No problems charging with two different  Samsung wall chargers. Any suggestion please?

Solution: Try using the powerbank on a different phone and see if the problem is the same. If it is then you may have a faulty powerbank. It may not be providing the correct voltage or current required by your phone.

Another step you could take is to replace the USB cord used to connect your phone to the powerbank. If this cord is defective then you will not be able to charge your phone properly.
