I discovered the reason for the problem.: Substratum (Pitch Black layer) bug with last build. For whatever reason, only this menu has problems.
[Xiaomi Redmi 4a ROMs, Kernels, Recoveries, & Other] Blizwing:
The CPU usage is always high in this rom. This causes the device to heat up too much, where it actually hurts when holding the device. This problem increases while device is charging. Please look after it.

The random freezing problem still hasn't been completely solved.

These are the things that I experience almost everyday. The charging issue is Everytime though.

I hope it gets solved.

Can anyone help me. Everytime I have to update the ROM, I have to factory reset my phone, or else the ROM is struck on bootloop. Is there any other way to update the ROM without losing the app data.
[Xiaomi Redmi 4a ROMs, Kernels, Recoveries, & Other] Amir_espie:
Im sorry, how did u flash the update? The procedure?

Because my phone not having any problem on every update, i just clear dalvik cache and cache, then flash the update. Then it boot normally but It take a little longer times to boot up.
[Xiaomi Redmi 4a ROMs, Kernels, Recoveries, & Other] Blizwing:
Does it really work cause I clear cache, dalvik cache, system, and data. And then flash ROM with Gapps

Hmm, maybe that's why. Sorry but I don't know much in this thing. So that's why?
[Xiaomi Redmi 4a ROMs, Kernels, Recoveries, & Other] Amir_espie:
If u want to just update the rom, u just need to wipe dalvik cache, and cache only then flash the update. If u want to change to another rom, then u need to make a clean flash which u need to wipe all, the system, data, cache, dalvik cache and vendor.
[Xiaomi Redmi 4a ROMs, Kernels, Recoveries, & Other] Blizwing:
Oh, Ok. Thanks a bunch. Btw, does the update have a changelog?

Almost all works fine.

Some bugs:

USB PC charge state bug (is common for all ROMs, I don't know why)

Double tap to wake option can't been turned Off

Every boot has popup notification to choose default data transfer SIM card
[Xiaomi Redmi 4a ROMs, Kernels, Recoveries, & Other] Paul T:
For the sim card notification, flash the attached sim card selector fix through recovery, that should stop the notification popping at every boot
[Xiaomi Redmi 4a ROMs, Kernels, Recoveries, & Other] Blizwing:
Yes, and quite a few times. Like it was happening for 4 times in a single hour. But now is somewhat OK.

[Xiaomi Redmi 4a ROMs, Kernels, Recoveries, & Other] agenius5:
It's getting better with every build. I hope it becomes a perfect pie ROM. It has lot of features, design and feel is good. No major bugs are present now. One feature I request you is to add some options to customize launcher. It has no options to customize drawer and dock. Installing ruthless or rootless pixel launcher creates some issues. So please take care of that in next build. And thanks for the build.

[Xiaomi Redmi 4a ROMs, Kernels, Recoveries, & Other] semivanya:
What do you mean?

If you already has flashed previous ROM ver, then you need boot in to TWRP

make wipe Cache and Dalvik

Install ROM zip file

make wipe Cache and Dalvik

Reboot.

It is "dirty" flash without full wipe.

If u faced some issues then try to full re-install:

wipe Cache, Dalvik, Data, System.

Install ROM zip file.

make wipe Cache and Dalvik

Reboot.

Also most importantly. The face unlock is gone, i remember that when I flash Gapss there are installing face unlock, but when i check no facr unlock
[Xiaomi Redmi 4a ROMs, Kernels, Recoveries, & Other] elemefaaoo:
For face unlock you need to flash super or aroma gapps.

Nano Gapps or above is required for face unlock.

About Nano Gapps

Already using Nano GApps. When i'm using this rom for first time. There are face unlock

It's functioning normally again

Btw, I want to ask,How to return to Miui Stock ROM?
[Xiaomi Redmi 4a ROMs, Kernels, Recoveries, & Other] Blizwing:
I think something is not right about WiFi. Most of the time WiFi takes too long to connect or doesn't connect and is struck on 'Obtaining IP Address'. And when connected WiFi is too slow. But at the same time my other phone is working fine.

Also when I plug my charger the screen turns black sometimes and whatever app I am using gets refreshed. Like on Chrome, a webpage I opened gets refreshed after plugging the charger.

Also Bluetooth sometimes forgets about previously connected device, and has to be paired again.

Also there is also a certain option of audio:SBC in the connected device menu in Bluetooth. I have my headphones connected and when I turn that option on, developer options start crashing.

And the random freezes still exist. And when it occurs it happens too frequently. I have to leave my phone just lying around to not encounter it again.

The Led doesn't glow sometimes when charging.

And is there a way to get memory bar in the pie recents. If yes, please add it. It helps to track memory usage better.
