how are you?
I have an issue with my BB 9790. Last november, my blackberry was always shutting down for no specific reason and when i was turning on my smartphone again, the battery level was super low so I decided to change my battery. It worked without any problems for like 1 month and then, shits came back in a big truck. So i have a new battery ( brand is "polar cell", it's non-official ) and the problem is almost the same, my phone can works perfectely for a few hours and then it stops and reboots for like 2 or 3 times before it works again. And so on and so on. Apparently, there is no specific action which turns off the phone, the problem may appears as well if I want to text a girl I want to hook up with ( it's always good to try, nop? ) or if I want to use the browser or the camera. The only time when the issue doesn't appear is when my phone is on charge.
I tried to wipe it and to upload my OS but it doesn't seem to help.
I use SFR ( french company ) if it's matters.
So, i know there are some awesomes members here who will help me
Thanks for reading guys
