Galaxy 551, touchscreen problems

Im having a weird issue since the last 2 days with my samsung galaxy 551 (callisto), when i turn on the phone the touchscreen works perfectly, when i open the pyshical keyboard to write something, the touchscreen stop working, i have to turn off the screen, wait 2 or 3 seconds and turn on again and the touchscreen start working again, this issue are present since the last 2 days, i have mothns using custom roms (CM7.2, Jellybread,etc) and this problem are present in all those roms included the stock 2.3.6, is a hardware issue? and which component are faulty? thanks

Do you got any solution to your problem?. I have nearly your same problem, but the touchscreen isnt working. I got to work it sometimes by locking the screen and unlocking it with the power button, but since yestarday that workaround is not working anymore. Any ideas?.

[Q] Touchscreen recognizes s-pen but not finger

A few days ago my touchscreen stopped recognizing my finger when I would swipe or do anything. I tried the s-pen and it works fine. I have rebooted it, done a soft reboot, and totally reset the phone to the factory settings. I have had the phone for about a month now. Any help would be nice

I had the same problem, and it only gets worse. I swapped mine out, free of charge. So, I would do the same.

Restoring Touch screen in note 4.
I´ve got the same problem. My Galaxy Note 4 (N910F) After installing CWM only a part of the screen responds to touch but works fine with the SPen, seems to be de-calibrated. After a few days looking arround I've found that there´s a method to reset wacom and the touch screen.
In the phone app, type *#2663# . It appears a screen that give you some options, I´ve reseted all the firmware options of wacom and touch screen. Then, all worked fine again.
When I´ve some more time I´ll put some screenshots.
Hope that can help some one to solve this anoying problem!!!

thank you
oh man, thank you so much you are a genius. I really thought my digitizer win bad until I found you post once again thank you

Note 4 Touchscreen Calibration
Huge THANKS for helping me out. Was installing a recovery with Odin and all of the sudden my touchscreen was so far off I couldn't use the phone. Tried going back to stock, no luck, the touchpad was still out of calibration. Couldn't get TWRP to restore cause I couldn't press the buttons, then when I somehow did get it to restore (lineage) it did no good. Out of desperation tried the s-pen and found out it was working just fine. So, using the s-pen, I applied your *#2663# trick, updated everything on the screen, and now my Note 4 is back up and running normally! Can't say thank you enough...
