i don't think the seller con u, its just that this is a 2nd hand phone, probably the old owner saw this problem, and sold it off. You're just unlucky to have bought it up.
what do you mean when u say , take out sim card also restart? If you take the sim card out, i'm sure u off the phone first right?
not sure if battery may be causing this, go back to the seller, since they're your old friends, and spell out your concerns, if battery problem, can be easily checked out, just put another battery in and check..
it was discussed early in this thread, anyway here's the info on the latest V20 firmware.
