So my problems. because i dont know the model i cant upgrade/update android. It didnt come with an sd card so ive got my cameras card in there and it provides a total of 3.68gb, how much do i need to make it run quicker. its freaking slow. I dont have alot of games on it because it wont load them, not enough memory maybe?
also the lady who had it done a complete factory reset before she gave it to me so i cant download any pdf files or use an ereader app, i get the error message (no program to open document) well something like that anyway,same meaning.
Where do I start?
