[Q] THL W8S Issue - Lock Up, Screen Fade, Auto-Reboot

Received this phone (THL W8S) 5 days ago, and straight out of the box it has had a serious issue where the phone will lock up, the screen will fade slowly to black, and then reboot itself. The problem occurs both after factory resetting AND in safe mode.
The phone is unrooted and running the stock ROM.
Basically during use, the screen suddenly becomes unresponsive to touch and the physical buttons (home, volume, power) all stop functioning. As soon as the phone locks up this way, the screen slowly fades to black over about 60 seconds, at which point I have to leave it to fade completely before it reboots itself.
It happens most frequently when using any browser (stock, or otherwise) taking from less than 5 seconds to around 5min before the random lock up occurs) but also happens when scrolling through messages; scrolling through emails in either of the stock apps; using a compass app which came pre-installed (very quickly).
Initially I thought it might have to do with WiFi, but problem also cropped up with WiFi off, using 2/3G. Then in troubleshooting also managed to get it to happen using the camera (lot of motion, and repeatedly taking snaps).
Also odd is that the batteries I received in the box were generic black ones, not the official stamped/logo'ed THL ones I've seen on every website and every unboxing of this particular phone. So while there's a possibility this may be a battery issue, the fact that the phone hasn't done this while using a more battery draining app (Beach Buggy Blitz; Rayman Jungle Run) makes me think this is a deeper hardware fault related to , although I don't know enough about voltages and such to rule it out completely.
I have a couple videos showing the problem, but unfortunately I'm not allowed to put the links here. Should both be easily found by searching:

System Unresponsive with 5.1 Stock Rooted

Anyone having the same issue and have found a solution?
Phone suddenly stuck at some instances even with non-extensive usage.
Yesterday I was only using Facebook app. When messenger bubble pop up, my phone suddenly spiked. Moved once and then it got stuck already. You'll notice that it's not Facebook app only that's not functioning since nav. buttons are also stuck. You can't go press home and clear recent apps/hibernate apps. Power and volume buttons are also not functional.
So I assume the main system crashed. I only did a long press on power button to restart.
I installed Franco kernel r73, and thought that issue would only occur with stock kernel.
However, it occurred again today, I was viewing photos in Stock Photos app. I haven't started viewing the first 10 images yet, so memory should not be consuming that much. I turned on the auto rotate to view the image larger. When I turned the phone landscape, it reacted like it's about to rotate. And suddenly it got stuck. This time, power button is functional. It turns the screen on and off but it still turns to the same stuck screen, not the lock screen.
I've been experiencing this since 5.0.1. and almost everyday since I updated to 5.1.
I'm not sure if this is a hardware issue on my unit since mine is already about 1 year and a half old. I don't want to buy another phone yet!
Or is this a common issue nowadays due to Lollipop upgrade. If so, then could you provide temporary fix before they update this on 5.1.1.
Thanks a lot!

I had something similar . When I put forward the curtain hangs notice and then everything worked fine

Meh

I've seen this behavior on my Nexus 5 only on 5.1, and I'm pretty sure, it was introduced with that specific lollibug version. It's really annoying, that you have to reboot the phone every two or three days to avoid the freezes.
There's already in issue for that, it has got the ID 161032.

Crackling Audio Problem

Non-rooted. Not dropped. No water exposure. Since day one.
I have had issues with my sound on my S6. Audio played through the main speaker has a crackling sound whenever audio is played with the SCREEN ON. This applies to videos, music in any app, but NOT when a call is on speaker phone. If I turn the screen off while listening to music, no crackle. Right when I turn the screen back on, crackle. Haven't downloaded any audio equalizers or anything like that. Everything is stock. Tried a reset, a reboot and a cache clear.
I haven't had time to take it into a Verizon store but will before the 14 days is up if no body is able to help.
Thanks in advance.

Did you figure out what the issue was? This is still happening to me!

I have the same problem with my AT&T S6 Active. The issue shows about 30% of the time, yesterday even while playing Clash of Clans, so it can't be the settings, I'm prone to think it's a driver issues. I also experience problems with the camera where if I haven't used it in a while it will shake, trying to image stabilize for around 3-5 seconds. Another issue I have is with trying to get the screen on, sometimes I will have to push the ON button 5-6 times before the screen comes on long enough for me to swipe my unlock pattern. After having owned a S2 and S4 Active I gotta say I'm extremely disappointed with Samsung. Without even getting into the whole No Removable SD card slot argument. My next phone will be a Nexus.

This issue stopped for me a couple weeks ago after the latest update which includes the application optimization/battery saver. After this the problem stopped, so I am assuming the upgrade ended it, or one of the apps that is now "optimized" was the cause of the problem.

Unfortunately the new update to Android 5.1.1 which I applied 2 weeks ago did not stop it for me. Just the day before yesterday the crackling even happened why my phone played the Alarm Clock tune I had set. It's gotta be a driver problem if it's happening on the Alarm Clock, or maybe even a faulty speaker but it's not happening all the time. Anyway, for this and a lot of other reasons I decided to part way with Samsung on my next phone.

Hi
I have the same problem. Any solution?!

So I ended up calling Samsung about this because it has been driving me nuts. We have narrowed it down to it being third party apps. Having said that, it could also be the setting under display causing the third party apps to malfunction. I went to settings>display> changed from adaptive you AMOLED cinema. I also removed most 3rd party apps from my phone that I downloaded in the past week. I haven't had the issue come back yet. Fingers crossed!

This is a display issue. Go to settings, display, change screen mode to anything BUT adaptive. Adaptive screen mode is not compatible with many 3rd party apps. Hope this helps!

Note Edge 2 stuttering

Hello everybody! My phone (SM N915F) has a problem of stuttering/lag spike. Every 7 to 15 seconds phone gets stuck for about 1 second. When using an app (say, camera) every 4-6 seconds I get a lag spike. I tried to solve this myself, I checked if this is a software problem (changed rom, 3 different roms), tried in recovery if it lags (it does not), tried other apps etc. I checked logcat to see what happens when phone gets stuck, I saw a service(?) choreographer says "choreographer skipped N frames", which as I searched on internet, choreographer syncs apps with display, so actually screen does not gets rendered for N frames for no reason. Did anybody ever had this issue? I have assured there is no storage problem.
