Rispondi a "Unable to read memory card"It could be that your phone does not support a memory card of the size you are using. It could be that the reader is dirty, and needs to be cleaned or replaced.
Rispondi a "Keyboard and power button not working"You should go to someone, and repair the wire. It might be the reason! Update (02/19/2019): It also could have been the fact that something spilled on the keyboard, but probably the components and wiring. There is also the fact that it is to old to survive!
