I have updated my system with origin OS at the first day when it was in the trial version, I feel just little bit smoother than the Funtouch OS, but although the OS is not supporting good enough to some apps like phone dialing, contacts, (iQOO/vivo app) etc. In the time of scrolling it get lagged and gives anger full experience, and also the drag and drop features not working for the WhatsApp also that's the main bug found, when I tried to share photos in the drag and drop it shows what's up not supported in the origin island.
And I suggest all other iQOO neo 7 pro users that not to update your new OS unless it appears in the main software version section( I mean don't update the trial version)
