[Samsung Galaxy S5 Neo ROMs, Kernels, Recoveries, &] nanquan:
Review so far and list of main problems

Been using it for a couple of days now. Noticeable speed improvement. More responsive and a lot less lag when compared to my previous Nougat 7.0 Samsung ROM (Zapyanovv ROM v2.1).

Great job, but unfortunately here is also a list of problems I encountered:

Screen doesn't turn on - there is a HUGE delay when trying to turn the screen on using the power button, or home button. It can take up to 10 seconds sometimes or more for it to respond. This doesn't happen every time but it happens very often. UPDATE: Yesterday it was so bad I couldn't wake my phone at all after several minutes of repeatedly pressing the Power button. Had to physically remove the battery and restart.

Phantom screen touches - not sure how to replicate this problem as it seems to happen randomly - without touching the screen the phone goes "crazy" and just starts reacting to "phantom" touches. I've had this so far while using apps like Whatsapp and Gmail, and in the system itself. For example I was typing a message in Whatsapp, and suddenly the phone just started "typing" randomly on the keyboard without me even touching it. UPDATE: I used an app called "Touchscreen Calibration" (link) as just generally speaking the screen wasn't sensitive enough and it felt like a constant struggle just to operate my phone. After running the calibration process and rebooting, HUGE difference. Everything is super smooth now. I am hoping this was related and will also fix the "ghost typing" problem. UPDATE#2: It didn't.

Camera keeps crashing - The camera app would work at first but after a while it will freeze. Once this happens, closing and reopening the app doesn't help. I've tried to force app close, clear cache & data, but if you try to launch it again all you get is a black screen. It seems the camera gets frozen on the hardware level. Only a phone reboot makes the camera work again. I also tried 3rd party camera apps and the result is exactly the same.

Very fast battery drain - When the phone is on standby and the screen is off it's okay (UPDATE: Even on standby the battery drains rapidly). But as soon as you start using the phone the battery starts to drain very rapidly. And I'm not even talking about heavy usage like games. Just some light browsing, emails, installing some apps etc. I've tried adjusting the screen brightness to a minimum, but no matter what I do I get extreme battery drain once the phone is not in standby. Coming from my previous ROM and same usage patterns, the difference is very noticeable. Downloaded and installed SystemPanel2 and gave it full permissions in order to try to and trace the source of the power drain to a particular app(s) or system process(s). But it couldn't identify the problem. Just says that the most significant power drain is "unaccounted".

Apps Randomly Uninstalling - I've had this happen TWICE so far. First Greenify just randomly uninstalled. I have its shortcut on the home screen to Hibernate apps with one touch, suddenly I press it and it says the app isn't installed (wtf?! o_O). Then another time after a phone restart suddenly the Whatsapp shortcut on my home screen disappeared. Checked the app drawer and it was no longer installed. Went to Google Play Store and confirmed it, as it was prompting me to install the app again. After reinstalling them from play store they both worked fine, but this is VERY STRANGE!!

Phone gets really hot (occasionally) - I have not been able to pin this on any specific action. It seems for no reason the phone will occasionally get VERY hot. I guess all things considered it's a relatively minor issue, and doesn't happen all that often, but still not ideal.

These are the main problems the ROM currently has from my experience. I really hope the OP can fix them in an upcoming update. Really nice ROM I like using it a lot except the above issues.

My device is Samsung Galaxy S5 neo SM-G903F.

Thanks!
