In my ZUK Z2, RoarTheGapps_20211207 which you provided in G apps link in crDroid v8.2, is installed in twrp but after boot there is no any apps related to Gapps only stock apps showing

Great to see the crdroid 8.4 (android 12.1) build for Lenovo Zuk Z2Plus. Appreciate your efforts.

Can you add 'disable U Touch' or all the customisation for U Touch? I mean I like the touch disabled and button working.

Also Bluetooth calling is bugged, cannot hear audio while in call. Audio FX is not working at all. Please use Fixy 4.4 vendor kernel, its working much better than stock, battery life and temperatures are under control.

Hello,

Thank you for your work.
Android Auto doesn't work I tried different gapps, crDroid 8.4, 8.2.

Continues boot looping, help.

Continues boot looping, help.

Have you done the installation based on the 1st post (please see below)? On the other hand, you tried to do update from a different OS, or does your Zuk have had at least a Zui 3.5 installed before you try to install this OS? To be honest, I prefer clean installation any time I try an OS, to avoid problems, doesn`t mean I`ll not encounter any problem, but it`s reduced. On the other hand, if I know well then older Zui versions are not suitable to use newer OS`s (newer than Android 9 or Android 10).

First time installation:

• Backup your data to PC // If Something Goes Wrong
• Flash recovery and boot to recovery
• Wipe system, data, cache and format data, then reboot to recovery
• Copy crDroid and Gapps to internal memory then flash them in TWRP in same order
• Reboot and enjoy
• Optional reboot again after first boot to flash Magisk for root

[LineArc]

Thanks for the rom. I am having issues. My phone is heating and restarting often.When not in use nothing happens,but the battery goes down faster even when not in use.Hope you can help me out. I flashed the rom exactly according to the instructions given.

 

[XeroKen]

Reverted back to crdroid version 11 and works well without any restarts or massive battery drain. Hope you can look into this issue. Thanks

 

[Gagandaywal]

is this build having any bugs ?

 

[voske15]

audio effects broken(no dsp will work); drain seems ok; heating normal for this phone

1) Audio is dead in any type of Call (Phone call, Discord, WhatsApp Call) over bluetooth. Also there is a bug when I connect to discord call while using earphones over audio jack, the audio has super heavy bass and left sided, it can be fixed when you disconnect call and play video and while it plays you connect to the call.

2) FlameGapps installs Wallpaper & Styles app and when you open it to change wallpapers from the launcher or any other options it crashes. Forced to use from settings.

3) Builds would get better if integrated Google apps so that we don't need alternatives like Miui trash apps. Or make seperate non-gapps variant of builds.

4) CPU is set to Interactive which makes it run hot. A better kernel governor is needed for better battery as this phone is so old I can't keep replacing battery every 3 months.

I faced no issue with my z2 plus so far with this rom, my z2 plus is 5 years old and I've not done any battery replacement yet

I was on Android 12 Xtended rom then first I flashed latest twrp available officially here for z2 plus

Download twrp-3.6.2_9-0-z2_plus.img

Download page for twrp-3.6.2_9-0-z2_plus.img

dl.twrp.me

Then wiped dalvik,system,data and cache then within install zip menu first I selected latest crdroid rom zip downloaded from here

https://sourceforge.net/projects/crdroid/files/z2_plus/8.x/crDroidAndroid-12.1-20220613-z2_plus-v8.6.zip/download

then I've added latest opengapps zip as well in batch downloaded from here

open_gapps-arm64-12L-nano-20220705-UNOFFICIAL_MOD.zip

drive.google.com

then I swiped flash button and after completion clicked on reboot button and phone booted properly and working fine now and as compare to other android 12 rom this rom runs phone cooler

Just facing one issue which I also faced in last rom as well is that sometime when phone call is coming and phone rings then phone shutdowns very quickly during ringing but after starting phone works normally

Hi, This OS works really great having some minor issues but It's managable. It runs really smooth but not optimized for battery. If we can have a feature like background app manager, It would be great.
One issue is related to the vibration setting, where it won't work for vibrate and ring gradully, Or if I turned of vibration for ring. Then phone vibration setting works as silent. It's should vibrate I think, Please help if possible.
Thanks

Replaced the battery and the draining part vanished, but there are random reboots when the phone is in sleep mode, also the heating is still present and more so if wifi or mobile data is active. I guess this is because of the cpu governor which is more aggressive towards performance than battery saving. Despite some minor bugs which needs to be fixed the rom works very well. I flashed magisk for root but it caused random reboots and sluggishness even though i had not installed any module, so i uninstalled it completely and wiped system, data, dalvik art cache/cache, internal storage and format data as well and did a clean flash which worked of course without root, but still random reboots remain. Hope you can look into it. I am at the latest version crdroid v8.7 android 12. Also i would like to ask if the rom is EOL or updates are going to continue.
