contentious off & on
my phone contentious automatically off .
Hi abdulmenan, here are some answers to some previous questions for your model. I would start with a new battery first. I hope this helps. Please let us know, Thanks, John
Galaxy will not turn on
No matter what you do Galaxy won't turn on or is continuously restarting.
If your Galaxy won't turn on you may simply have a drained or dead battery, especially if the device hasn't been used in a while. Try plugging your galaxy into a computer or AC adapter and wait to see if device starts to charge. If device does not respond to either charging source you may need a battery replacement.
If your Galaxy does not respond to being plugged into a power source, the most plausible problem might be the motherboard. For instruction on how to replace motherboard view this page
