Help Charging problem

[RikuH]

Hello!

I got an unusual problem. My SGS2 have worked fine for a year, but today my phone don't work normally.

I got a call, and then I got a notification, which reported, that driving mode is switched on. When I stopped the call, my phone crashed. I restarted the phone, and the notification was still on notification area. I hadn't switched driving mode on, but still the notification was here. Somehow the notification disappeared suddenly.

Then switched off my phone, and i got the screen which notify me the level of battery, just like phone is in charger, although my phone wasn't charging. Why?

Now my phone doesn't recharge with normal charger, but I have to charge the phone with desktop dock, it's only way to recharge the phone.

What can I do with this strange problem?

Why the phone recharge only with desktop dock?

Why get I recharging screen, when my phone is off, although it is not switched to charger?


Thank you for answer and sorry for bad english!
Greetings from Finland!

Check the microUSB port on the base of the handset for dust, fluff or other debris, as this can cause similar problems.
If all seems clear and the problem remains, try another known-good charger to rule out a fault with the other.

If the issue persists then the USB port itself may have developed a fault and will require replacing.

Thank you for your answer!

I just read some forums and I read that this kind of problems can just be caused by microUSB. Driving mode randomly on, recharging problems, etc...

I discovered microUSB port and there were lot of dust. I tried to clean it but the same problem repeats.

I will try to clean it better and if it doesn't work I'll send the phone to service.
Fortunately I have warranty yet...
