Hi Zaito, so sorry for delay, I have only just logged on in ages.
I tested it on GS5 only - installed UT 24.04 because it was the only way to make phonecalls when 3g packed up. Nothing I did enabled Waydroid to persist. Meaning that if waydroid was closed for any reason, you couldn't reboot it without a completely fresh installation. This rectified in June with a new UT update. Everything works well in both UT and Waydroid with one exception; there is no clipboard on waydroid. Which means you cannot copy or paste anything in any circumstances. If I need waydroid copy facilities I have to use another phone running UT20.04.
Hope all is well.
