Just to document, I tried with this setup : Custom ZRAM Optimization (4 GB + Swappiness=20) with example for Xperia 10 III and tested on C2 too— Guide Available
But without any improvement.

I’ve been the lucky one today : it started.
I used this luck to resync Whisperfish…
This morning my Xperia 10iii (SFOS 5.0.0.77) entered the Android restart loop as well. After several attempts, I managed to extract these logs:

KB until OOM, target footprint 268435456, growth limit 268435456; giving up on allocation because <1% of heap free after GC.
So it’s the heap thing. Do we really not have a solution to this? This is terrible.
EDIT: This is a full log from a crash:

It seems I found a solution that has worked for me (for now?)
First I recorded several logcat logs:

🐟 ❯ while true;sudo appsupport-attach /system/bin/logcat | grep -E 'system_server|AndroidRuntime' | tee ~/$(date +%Y%m%d%H%M%S%z-logcat.log);find -maxdepth 1 -iname '*-logcat.log' -empty -delete;sleep 1;end
<lots of output>

I then grepped for the OutOfMemoryError:
🐟 ❯ grep -A30 'OutOfMemory' *-logcat.log | grep 'OutOfMemory\|\bat\b'
And this UsageStats thing kept popping up:

So I searched for files or folders named usagestats:
🐟 ❯ sudo find /home -type d -name "usagestats" 2>/dev/null
/home/.appsupport/instance/defaultuser/data/system_ce/0/usagestats
As nothing was working anyway, I thought I’d just move that directory out of the way, while stopping the appsupport completely:
🐟 ❯ sudo systemctl stop appsupport@defaultuser.service
🐟 ❯ sudo mv /home/.appsupport/instance/defaultuser/data/system_ce/0/usagestats{,.bak}
🐟 ❯ sudo systemctl restart appsupport@defaultuser.service
After that, I can use Android apps as usual, no crashes.

Nice! My AAS is currently booting normally, but I will definitely check this out if it doesn’t start again. It won’t still be a real solution but at least a workaround.
