Phone has several problems. Sound quality from mic is very poor to the extent that it is inaudible few times a day.
Touch screen does not work frequently and you have to unlock the phone after repeated tryings. Speaker gets automatically on frequently.
While you’re in a call or trying to end a call, automatically another unintentional number gets dialled.
This a regular habit. Touch screen gets locked and does not work sometimes when you’re trying to press the answer key. Even when on a call you are unable to end the call.
