I have strange touchscreen problem on my sm-n910f. After I flashed custom recovery and one of the custom roms my touchscreen stopped working properly, even if I revert to stock. It looks like touch surface became smaller, right and bottom part of the screen doesn't work any more. Phone seems to use smaller surface for touch, so to press very bottom icon I need to press 1-2cm above it. It behaves the same in any rom and any recovery. See photos, I activated show touches in dev options. I try to look if anyone had the same problem, but I couldn't find anything. Any ideas?

I forgot to add that spen works perfectly fine.

Well I know what I did wrong so just in case someone else has the same problem: I flashed wrong recovery, one for n915f (no idea how I managed to get that file instead of proper one). Funny enough reflashing good one or flashing stock rom doesn't solve my problem. Over the weekend I will go to Samsung shop, hope they can help me.

I tried to flash original firmware and two custom roms, no change unfortunately. I also believe it is not hardware fault, but I have no idea how to fix it.

I love Samsung warranty policy in the UK, 28 days from purchase date they replace faulty device without asking for a reason, so I got mine replaced. Pure luck.
I still believe it would be know if what I have done is reversible. I understand why flashing wrong recovery is messing with graphic driver, but I would like to know why flashing proper one doesn't solve it.
I would appreciate if someone could share some light on that matter.

Probably has to do something with partition size. When you flashed the wrong recovery, a repartition was done and it messed up your device. Flashing the right one in a messed up partition did not solve the problem. Perhaps if you had tried to flash the appropriate PIT File for your device, the problem would have been solved. But, in the future, the safest option is to be extra careful about which files you flash. Glad you got it sorted out!

I tried PIT file too, no go As I said my problem is sorted, but fact that I do not know if it could have been resolved without replacement bothers me a little bit

If the PIT file didn't work, then it seems that the replacement was the only way to go.
