Phone is acting weird like it was back button pressing itself.

Phone is new. It was never used before. It was unboxed from the sealed package. After powering it is acting strangely. It vibrates and it looks like back button is being pressed constantly.

I have opened it up.

When it is opened it is not doing that but I can’t use opened phone :)

Any help will be appreciated. ( I have tried to change touch sensitivity but it wouldn’t help)

If the bottom lights are flashing it usually means the battery is flat and needs to charge up to turn on.

Leave it plugged in the charger for about an hour and it should turn off.

If you just opened it up sealed in box don't forget to insert the battery. (I could be wrong but this model may not have user battery)

It is not power issue. Phone is charging without problems. Its starts also without problems but after a while it acts like back button was being pressed repeatedly. It vibrates and all apps/setting are closing...
