Samsung mobile Tri-Band SGH-V200 Problem

The battery has failed in all likelihood. The charge indicator on phones is not accurate as it only measures voltage and not amperage. Most Samsung devices use batteries that are not intended to be run completely dead. New batteries should be allowed to discard to less than 10% and fully recharged the first 4times of use. After that it ddoesn't matter when it's recharged.

taking it to the service center is much advisable

Sir i hope my answer will help you.

all you have to do my friend is got to settings and then go to privacy and all you have to do is enter your password

I am not really familiar with SIM cards but have you tried re-programming the phone or updating the software?

you should try a new battery and if that does not work then you need to take the phone to a mobile service center close to you and have them flash the firmware on the phone to correct thise.

search the programme for it on net or send it via infrared or blietooth
