About October last year when i received the phone i noticed a few minor freezes when playing a video off the external sd card and it crashed my phone once. Once the new year hit all was fine no problems what so ever then about 2 weeks ago when i was watching videos the player crashed and locked up my phone causing me to restart which took a very long time. Now this has become a regular occurrence when playing from the external sd card. Sometimes it will crash at 2 minutes other times such as the time i was watching a movie from video hub it crashed at 2 hours in. I have factory reset the phone and the problem still occurs. I live no where near a Samsung service center and the nearest one is in the mainland UK and its carry in only. Any ideas on what i should do? I bought the phone from Amazon.
