[One (M9) Original Android Development] handynoobinator:
Now 02.06.2024 its Android 12 and Aicp is a very very nice OS, it gives you good control over your device.

All bugs i descripe in this post are solved, its a perfect usable rom.

Simple Recall of steps to solve issues, maybe uncomplete: insert sim, activate all location services, turn on battery saver, twrp wipe cache dcache and system before flash update rom.

Link to recent builds: https://dwnld.aicp-rom.com/ (m9 hima), post 1 here from dev has link to old builds from 2022

This Rom is really very very very goooood, the camera makes wonderful HDR, you can supplement it with .... in order to get Panorama and Photosphere: Pixel-Kamera_4.1.006.126161292_apkcombo.com.apk (runs on every device i have)

For RAW use FreeDcam

Solved:

Bug: Draws 150mA in Standby, or 10% of 2600mAh Battery in 1 hour.

0mA if powered off.

wiped and flashed again, deactivated everything on the dropdown menu = 30mA which should be okay. Need research

wtf my twrp backup is deleted, this is stupid, it was on th local storage in TWRP!

Also the data of some apps, why is there stuff displayed of different partitions, its not user friendly, its a android thing.

After reboot 150mA again, its unusable.

Solved:

aicp_hima_s-17.1-WEEKLY-20240421.zip

the same 110-150mA in Standby, after the first boot one time it goes down to 30mA whicht should be normal, but is does not stay that way, after reboot.

both have wlan symbol always activated and in menu it is turned off the same time (fixed with sim insert)

tried every setting, like tab to wake, notifications, battery saver, always same result

this rom is very good, very sad

Solution:

Inserted Sim Card, turned off mobile data (same icon problem as wifi), had to turn on location in order to get sim working ?!

4mA !!!!! with and without airplane mode SUCCESS!!!!!!!!

This phone is timeless i would say, its perfect, i put a 18650 holder + bms of battery + mosfet polarity protection on the back for power. The only thing what is not so good is that the camera module is only fixed on one side, if you take it apart you will pull on the flat cable of the cameramodule which is sticked to the backcasing with double sided foam tape. You can heat it up with a hairdryier or apply a !!tiny!!! amount of alcohol or acetone to the spot, if you have opened the case on the bottom a litte. ( it must not get into the camera module, so better not to use solvent ) but on the mainboard bottom you have to use solvent, and the battery.

@CyanRose: you found the screenshot folder of the device, applause :)

Little Bug: if open camera is closed status bar has to be activated again with swiping down and up.

possible bug: Want to share high battery usage, this phone is mostly on airplane mode, wifi off, location on, sim inserted, double tap to wake and sleep on: screenshot

camera and messenger drains battery very fast, maybe for 15 pictures a big portjion of 3000mAh is used up.

20% of real 2500mAh in 24h standby with airplane mode and only gps on. 243idle 199simplexchat 25osmand 13androidsystem

its not normal, my m8 with lineage only draws 1%, this means i have to constantly switch my 18650s, but everything works good.

10mA in standby mode, 600mA when used, i think this is mormal, standby should last 10 days but it lasts maybe 1-3 days with minimal usage. Cant explain that, but its usable, but not optimal. I will try to turn battery saver on and will have a look what happens next.

Solution:

I think its necessary to activate all location services in settings, like suggested in lineage19.1 from same dev. Also turning on battery saver in settings. It seems like the battery drain is down to normal. Using Apps doesnt heat up phone anymore but they are not slower.

Update: Seems like the phone battery now lasts endlessly, perfect now im totally happy, because is like it so much.

Improtant:

For Backup, store the partitions: -system -data -boot with twrp https://twrp.me/faq/whattobackup.html

For Flash new version wipe partitions: -system -chace -dalvik cache then back install: aicpxxx.zip (if system not wiped random reboots)
