@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.
