hey,
i have a a920 and i am very pleased with it except for some parts:
-All of the sudden i cannot view videos anymore i used to be able to but now all the videos i record i can hear the sound but a black screen is all that shows.

-Whenever i try to add a name of a contact in it is impossible because whenever i type in i get other letters or numbers that i am not wanting. (Kinda of like major "lag" problems or something)
-Ex: i press the number 5 trying to get a J, and i see a j for about a second
then it changes to a 5.

-Also, my phone is "lagging" or whatever you would call it for a phone, but that is probly normal

Does anyone have any reccomondations on what i should do?

thanks
