[Q] [Problem] Screen "twinkle" and shut down

Hi guys,

First of all sorry if my english hurts your eyes ;)

I am having an issue, but it did not look like the same as I saw about other people.

I recently installed the german version of JB on my Note. After some days, my screen started to "twinkle" or "flickering" (I don't really understand the difference between these 2 words). And my Note becomes hot. There is kind of battery drain too. Sometimes it shut down and I have to reboot it.

The fact is that I have bought my Note 6 months ago (new one), and I bought a second battery. When one is empty I got the official Samsung charger to charge it while the other one is charging with the phone.

My 2 batteries are relativily new. When I see that changing the battery is the solution, I dont see it can be applied for me. I tried to change kernel/rom/radio with clean flashes, the situation remain the same.

Do you have any idea where the problem could come from?

Thank you,

Jonathan
