Hello, I have a Samsung S5PV210 android google tablet. Every time I try to type my password, email, anything, I never get the right letters. Such as, if I type the letter b, I may get L. If I type the letter n, I may get s and so on. Is this something that can be fixed with a reset or just something I could do, or is it a problem that the tablet needs to be returned? Thank you.
