Galaxy A3 Unfortunately System UI Has Stopped Working

Problem: Was playing a game on my phone and it was a little warm but not out of the ordinary. Game froze tried to hit the home button it didn’t work. Then the “Unfortunately System UI Has Stopped Working” message came up and then my phone appeared to be locked, indicator was flashing. At this point my phone was at 30% battery but I couldn’t turn it off, force it off or get it to respond to any action. Overnight I think it died and the indicator Is gone. Nothing happens while charging it. Not sure which version I was using but I always had it up to date. I didn’t download anything crazy or do anything to compromise the phone.

Solution: Since it appears that the phone battery has run out of charge the first thing you will need to do is to charge the phone by following the steps listed below.

  • Clean the charging port of the phone using a can of compressed air. Make sure to remove any dirt or debris stuck in this port.
  • Charge the phone fors at least 20 minutes using a wall charger.
  • If there is no charging indicator then try using a different charging cord and wall charger. You should also try charging the phone from a computer USB port.
  • Turn on the phone by pressing and holding both power and volume down buttons for at least 10 seconds.
  • Once the phone has turned on I suggest that you backup your phone data then do a factory reset. This eliminates any software glitches that could be causing the problem.

If the above steps fails to fix the problem then this is most likely caused by a faulty hardware component already in which case you will need to bring the phone to a service center and have it checked.

Galaxy A3 Moisture Detected Error

Problem: My brother has a new phone which he has never used near water or anything that could conduct moisture into his phone but yet suddenly he saw that his phone was displaying a moisture error and he could not do anything about it. He tried cleaning the charging port but the little to no luck he could not manage to clean his port of this ”moisture”. He tried rebooting and clearing data for the usb settings but it did not make a difference. Please help me out to fix my brother’s phone.

Solution: The first thing that needs to be done in this case is to make sure that the charging port of the phone does not have any moisture. Use a hair dryer or a mini vacuum to remove any presence of moisture from this port. If the port is already dry and the error message still occurs then this is most likely caused by a software glitch. Try restarting the phone then check if the issue still occurs. If it does then you will have to backup your phone data and do a factory reset.

Problem: Samsung A3. I plugged a mini-fan into my phone and it shut off. I can’t get it to turn back on at all. i tried charging the battery. There is no response to a charger (tried several different ones) i can’t even get it to factory reset. There is no response to any buttons being held. I’ve followed all your troubleshooting.

Solution: It’s very likely that the USB fan caused a short circuit and damaged a component of your phone. The best thing you can do right now is to clean the charging port of the phone using a can of compressed air then charge the phone using different charging cords and wall chargers. You should also check if the phone can charge from a computer USB port. Once the phone battery has sufficient charge try turning the device on.

In case the above steps fails to fix the problem and the phone remains unresponsive then you will have to bring this to a service center and have it repaired.
