Note 2 keeps shutting down/freezing once screen turns off - AT&T Samsung Galaxy Note II

Lets say my screen timeout is 15 secs. After 15 seconds, the screen turns off. If I don't turn the screen back on right away, the note 2's screen would just stay off and I think the phone shuts down too. I can't really do anything except remove the battery. I'm using stock rom on my note 2. Any solutions?

Screen lighting up issue

Hello i was wondering why the screen on my galaxy s III T-mobile will just randomly light up and stay lit up until i turn it off. It does this about once every half hour and it is very annoying. Also, whenever i receive a text message, the screen never turns off. And ideas as to why? Thanks
On my vzw version sometimes the screen doesn't shut off unless I press the power key. I had to reboot to resolve the issue. Hasn't happened in a couple days though. I wonder if it's a screen bug.

Phone turns on but black screen

I was at the store and my phone was about 5% battery life, so I turned off my phone. And got home plugged my phone in the charger and came back couple minutes later. When I turned my phone on, I got the samsung logo then nothing else. I feel the phone vibrate when turning on. Then I heard my phone unlock but the screen was black with multi-color dots all over the screen. The LEDs, home, back, etc buttons light up fine, hear the volume when I turn it up but just get this black screen with those dots.
Yes I did flash an rom but thats been weeks ago and never had an issue. Its the carbon 4.2 rom.

[Q] Power button lag, from screen off.

Just wondering if anyone else has been experiencing a lag for the screen to turn on from a booted phone with screen off. I'm on fw 4.4.2 nuts stipped version. It can take up 8 to ten seconds for the screen to turn on sometimes other times a couple of seconds, if so has anyone found a fix for this other than wait for 233. Ps it only happens when swipe or security enabled for lock screen. With option none all works ok

Delayed response on lock button press

I have a Note 8 Global Version with MIUI 11. If my phone is locked and screen is off and I press the lock button or even scan my finger, it is taking approximately 4 to 5 seconds for the screen to be lit. A few information if it helps:
1. Let's say in lock screen the screen is supposed to be lit for 5 seconds. I press the lock button. Wait 3 seconds. Then the screen light turns on. But just after 2 seconds the screen turns off. It means the processor does read the button press immediately but somehow fails to turn the screen on immediately.
2. After the MIUI 11 update I was tinkering with the new options. And I found one old option actually - double tab lock button to start camera. I turned that on and checked how that works. That was the first time I noticed the delay of 3/4 seconds. So I thought it was related and disabled it. But still the issue persists.
Never happened to me. How much free RAM do you usually have free? Looks like the device is running slow in elaborating processes.
Do you notice other lags while normally using your phone during the day?
