Hello, I've been coming across the same issue on multiple n9510's-- periodically, the display will go black, or flicker or glitch out and become unresponsive. Many times I'll simply turn the device on and the initial screen will be a glitched out static mess but will eventually recover during the boot up process and display the correct output by the time it boots up. Things will go smoothly for a little while, then it will randomly go black-- and sometimes it will never come back.
My coworkers and I will extensively test these devices and they'll appear good and working to us so we'll sell them, but 100% of all our sold stock has come back within a month for display issues.
At this point, I'm chalking it up to sub-par components from the manufacturer, but maybe I'm overlooking something. Any chances that an update or a new rom/kernel will fix this? They're nice phones, and it's such a shame to see them come back for this issue so often. Anyone's 2 cents is greatly appreciated, even if you can just vouch for me that someone else in the world is having this problem as well. Thanks a bunch guys, and if I happen to find a solution I will definitely post it in this thread.
