[Galaxy Note 4 Android Development (Snapdragon)] Note4usr:
Just thought sharing this might help some people, so here it goes.

My Note 4 started freezing, restarting awhile ago and then I came across a thread in XDA advising to use Wakelock (option 4) and so I did.

Then the phone would keep working not freezing as much but sometimes kept restarting until it went (Qualcomm hs-usb QDloader 9008) and I after trying to find a solution I came across this thread.

Long story short, I had to follow everything the OP wrote to flash the phone via Odin (Yes I did have to freeze the phone). I managed to flash the phone successfully in Odin.

Then the phone came back to life but, it would still freeze (especially not using the phone for longer period of time like when I went to bed and yes Wakelock option 4 was active) and every time it froze, no matter what I did, the screen wouldn't come on, so, I had to take the battery off and put it in freezer for 30min or so to cool it down and then it would turn on without flashing or anything.

I was losing hope and then one night I tried to run Option 5 (Screen_dim_wake_lock) in Wakelock app for overnight and that night the phone didn't get frozen but, the phone screen would automatically keep lighting up every 10seconds from Dim Light to the brightness I set on the phone. It was as though if I wanted to unlock the phone and use it.

Something clicked in my mind, I then want to find out what the culprit that was trying to change the phone LCD light from Dim light to normal light. I tried to install Battery Wakelock app but after installing I found out it requires root after KitKat 4.2 OS. I gave up on rooting my phone cause of some app won't work in the rooted phone.

Luckily I noticed that when the phone LCD changes from Dim light to normal light, the down arrow was appearing indicating to Home button to unlock the phone using FINGER-PRINT option which sat up.

I decided to turn off FINGER-PRINT locking option. And when I did that, then magic happened!!! The phone screen stopped changing from Dim light to normal light. That was a very quick and lucky find for me to find out it was the FINGER-PRINT locking option that was lighting up the phone screen every 10seconds or so. And with that fixed, I turned of Wakelock and closed the app (I double checked the Wakelock app was not running in any option) and then with a little fear I left my phone in charging overnight and when I woke up I grabbed the phone to check if it was working or frozen. Yes! Success! (well partially)...so yeah the phone was up and running.

I decided to test it for few more days before posting this (possible solution) here in XDA. It has been 5 days now, my phone is running fine without Wakelock app and yes WITHOUT FINGERPRINT locking option (I hate fingerprint security now!) The only problem now is, when my phone turns off or I want to restart it, I still have to put in freezer to cool it down to be able to turn it on. Apart from that, the phone is working fine!

I would say, if you have the same problem with your Note, then it won't hurt to try this solution out and see. If it doesn't work for you then try to troubleshoot and find out (maybe) there could other system apps or 3rd party apps doing the evil thing in your phone.

If you have any questions, feel free to ask.

All the best everyone!
