I have found that at times (not consistently every time) when I leave my TF just sitting there and "sleeping" (ie not being used) and then at the end of the day I pick it up, the screen and all sensors are frozen - ie touching anywhere on the screen has no effect, changing orientation of the TF has no effect, etc...
The only thing that seems to fix it is a force power down (12 sec hold of power button) and restart....
Is this a known issue? Clearly it's not hardware as once rebooted it works fine.
If you mean that the screen is black/blank and everything is unresponsive then yes, it's a known issue that quite a few people seem to be having intermittently, me included.
Theres's a thread where people are trying to figure out what causes it here:

No the screen is not black - it lights up but none of the sensors are active (screen touch, orientation etc...)
I had this problem couple times touch screen did not respond except the home button.
After pressing home it started working fine

Anyone else having a problem where pushing the power button to turn the screen off, and then pushing the back button (sometimes with the menu button at the same time) turns the screen back on even after 10 seconds? I'm running TNT Lite 3.1.1 with needing to run the calibration issue. Seemed to happen after that, but not sure, and it was in 3.0 as well. But I did notice that if it's sleeping for a certain amount of time (undetermined at the moment), it does not work the same way.
I have encountered some strange issues with Galaxy R during the past few days. The first issue is when I plug in my headphones when the phone is idle (i.e. screen off) the menu key often fails to wake it up. Only the power button wakes it up. Sometimes, it wakes up but after a greater than normal delay This happens only when earbuds are inserted when screen is off.
Secondly, sometimes my touch screen and capacitive buttons loose their sensitivity for a couple of seconds (say about 10 seconds) and then come back to normal. The menu and power button works fine but the touch controls are lost.
Has any of you encountered the same? Please comment. Thank you!
Mine Galaxy R doesn't have any of this. I'm on 2.3.4 and you? I think its a defect. And where you wrote this:

I think that is normal because you cant unlock the phone by using the back or menu button.
As the title says the phone's screen won't turn on after I ended a longer call, i have to press the power button to get the screen working.
Did it happen to you also?I have this phone for 2 months but it never happened in the beginning, this seems to be a recent issue.
Is it a hardware issue or a software bug?I've tested the proximity sensor and it works just fine as much i can tell, it switches the screen of and on, it never happened to wake the screen during a call and to activate random keys.
Another strange thing that i noticed during a call:If have the keypad up and i lay the phone horizontally the screen won't turn off if i hover my hand over the proximity sensor but if i put the phone vertically the screen goes off or if i hide the keypad the screen also goes instantly off.
Hi Ive had the Galaxy S8 about slightly more than a week, and Im facing this recurring issue whereby the pressure-sensitive home button starts to take light taps as heavy presses, and on some occasions when i turn off the screen, it turns on by itself thinking that I made a hard press. I can feel it as the vibration motors are activated. I tested it using *#0*#, but it works perfectly fine there. Anyone else facing these issues? Can anyone tell me if this is a hardware fault or software?
I've just witnessed it turned phone off and back on and back to normal now had over a week only known this happen once about an hour ago
Never seen it turn on my accident, but it does glitch out sometimes. At times it can register a touch as a hard-press, and it does the double vibration every time I touch the home button. This is fixed with a screen off - screen on switch though, so not a problem for me, and I haven't experienced it after the new update
Got myself the S8 secondhand and while it looks immaculate, I also have this problem. At times the pressure sensitivity doesn't work at all, sometimes it will go through periods of immediately pressing and depressing, and sometimes it'll register a soft press of the home button as a hard press.
Think this is a hardware error? I've tried this in Ultra Power Saving mode and without my case on, and it's always repeatable.

I'm having the double vibration when I hard press the home button problem. It's a hardware problem? And how to fix it? I didn't understand the screen off - screen on switch solution

Double vibration? Isn't that what is meant to happen? The first vibration when pressing down simulates a real physical button being pushed down, and the second vibration when lifting your finger simulates you releasing the physical button. It's meant to happen, and it's not a hardware or a software problem.
What I meant with screen off - screen on solution is simply turning the screen off, and turning it back on again. It fixes a problem that occurs to me at times, where the double vibration happens every time I tap the virtual home button. Normally it's only meant to happen when pressing the virtual home button forcefully, not on light taps where no pressure is applied.
If the phone is in standby, with display turned off, if you double press the home button, or you keep it pressed, the phone will get back to phone mode with emergency call only. How to disable that damned festure? ?
Am i the only one whose screen, when it's off, doesn't turn back on properly? It registers both the fingerprint and the power "button" with haptic feedback, and the screen flickers quickly, but doesn't stay on until trying it finally works randomly, or if i use the squeeze gesture to open the camera immediately after pressing the power button. Locked and stocked too.
What is os version are you running?
Does this happen indoors or out?
I used to have an issue where auto brightness would immediately adjust to 0. The screen itself was on but the backlight was essentially turned of.
Only noticed it outside and auto-brightness was on (didn't even think that might be related to the issue! good call. If it happens again, I'll turn that off and see if the issue persists). Running 8.0.0.0 w/ 1.30.617.2 in USA
I have similar experience with my unlocked U12+ and may be Smart screen affected somehow screen back light. I've tried different combinations of settings (automatic Brightness on/off), Smart screen on/off and I noticed lack off problem in dark room. Even though some very strange reactions off haptic buttons (volume down by itself) makes me think about some general functionality problems of this device.
Has anyone noticed whether pressure on a particular point on the display affects the backlight?
When I squeeze moderately strong with two fingers in the area of the padlock (that is seen in a locked screen), it's the same as pressing the power button.
I've been using HTC flags for a long time, but for the first time I've come across such a touch-sensitive device. Every touch wakes him up, even in my pocket, which uses a battery.
I am terrified that there is no separate adjustment of the power and response style of touch-sensitive locations (haptic buttons, squeeze sensor)
