Buy a new phone.
K750 is very old model and its hardware not support this service.

there may be some dust particles entered into your phone that may be the reason for some of the buttons not working properly especially joystick .......if you have tool kit using it open your phone and using cloth try to clean the board .......if you are not confident of opening better take to near by service center to get your problem solved

Simple It's problem with your sim card. Try different sim card to cheak it.

I reckon it's a charging problem - mine did it! Charge it for about an hour, then switch the phone off. Turn it back on and charge as normal.

key pad clean and or keypad replaced tested ok

mine does that aswell i went into the o2 shop and they said that some little LED light had blown
