        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
