Haven't really tested charge speed, but 5G and WiFi hotspot work perfectly fine for me on the Quintus. Hotspot had a bug in 24.04-1.0, which was fixed in 24.04-1.1.

Updated. Still no notifications on teleports and cinnyUt, but therefore the endless counter of dekko in the launcher is fixed. Have some issues with the switch between 5g and LTE, sometimes I have to go into flightmode to be on the internet again by mobile data. Today - so a few days after the update - uAdBlockNG stopped working, emptying cache and a reinstall didn't work. Before and after the update I sometimes do not hear it ringing on the other side. I have the impression that battery drain is less than before... Headphones via usb are working now!

@smoore100 You may have to look at installing the minimum Android version requirement before going to UT. You can check with the Volla guys which one is required before upgrading to UT. Cheers.

Today I found that someone has a similar problem with the Volla Phone 22 : https://forums.ubports.com/topic/10983/volla-phone-22-very-laggy-performance/5?_=1756284607730 . Maybe both problems are caused by the same thing.

@TotalSonic : Thanks for the answer!
