I have two V300 phone, it was working properly until one day i am starting have charging problem. The screen shows: "Unable to charge"... I was able to correct it by replug it for several times.. and finally the phone goes dead. I aways get the error charging messgae... The good thing is the 1 year warrenty coverd this but it's already the 3rd time i have to request a replace phone sent to me!! The worse thing is , TMOBILE now even start to charge $10 shipping fee for the problem they generated.I will never buy the MOTOROLA phone with the same charger again.Stupid design that never consider durability.
