      I don't have this problem with my pixel 3a 24.04-2
      Before updated my redmi 9s I don't have any problem with ubuntu touch. Someone have the same problem ?

        Maybe could you try to clear cache with UT tweak tools

          I've already clear cache and that don't help. Waydroid seems never kill and more stable that native applications.
          Perhaps lowmemorykiller is too much aggressive

              Fixed with

              sudo mount -o remount,rw /
sudo nano /opt/halium-overlay/usr/libexec/lxc-android-config/device-hacks

              Add

              # disable lmk
echo "0,0,0,0,0,0" | tee /sys/module/lowmemorykiller/parameters/minfree
echo 0 | tee /sys/module/lowmemorykiller/parameters/enable_adaptive_lmk

              zram0 not created :

              phablet@ubuntu-phablet:~$ ls /dev/block/zram0 -al
ls: cannot access '/dev/block/zram0': No such file or directory

              Add 99-zram.rules :

              phablet@ubuntu-phablet:~$ cat /etc/udev/rules.d/99-zram.rules
ACTION=="add|change", SUBSYSTEM=="block", KERNEL=="zram[0-9]", SYMLINK+="block/%k"

              reboot

lrwxrwxrwx 1 root root 8 sept. 30 15:28 /dev/block/zram0 -> ../zram0

              After this fix I don't have any lowmemorykiller. And I don't lost any notification.

                Very impressive...
                I followed your exchanges on the French Telegram thread.
                I hope you remember where you parked your flying saucers, guys. 😉
