I've had a Wii U for a while now, and its touch screen is like broken beyond belief - (Displays but has trouble with touch sensors - can touch on left side and will register touch on the right side). And even though it was broken and the touch was funky, I accidentally dropped it face down on my floor which is carpet, and no harm was done, but then the touch screen actually showed some signs of touch working in more the correct spot when I picked it back up, so I quickly navigated through settings and calibrated it and everything worked perfect.... For like a day, after which I laid it on its back down on the table in which my stuff is set up and then it only barely worked again... After a long fight with the thing to calibrate the touch screen I found out that FSR it preserves or doesn't break again as long as I put it on its stand, setting vertical, when not in use. Later after I figured that out I forgot to do so, and simply let it lay on its back for another day without use, and now it's back to little to no touch working on the wrong side again... Could someone please explain to me why this happens and a fix without spending money?
