I recently got Origin Os 6 update in version trial on my Z9x 5g on 4th March. I used all its features, customized home and lock screen and here is my final review.

Origin OS 6 provides modern look and transparency effects even on budget phones like this. Animations have improved, performance boost is also there. I got battery drain for first 2 days but after that now, battery backup is crazy good like I can use my smartphone 2 days(gaming not included) without any problem on a single full charge. With gaming it gives a solid 1 day battery backup. They added a few basic features to the game mode which I personally like they are touch sampling rate(just like z10x) and brightness control directly from the game turbo. Mostly things are fine and it is such a huge upgrade from Funtouch OS 15 cauz that was more bulky and slightly more stuttery than this. The only thing I don't like is that though they have given tons of lock screen customisation as compared to Funtouch OS 15 but I personally feel like they should have given atleast transparency clock option in this phone also. I hope iQOO will give this feature in the next stable update. Flip card feature is also missing though. Let's see if they give that features to this also in the next updates. Also, there are a lot of bugs in this update like app animations sometime freezes and sometimes they work. Volume rocker controls are also delayed. Stopwatch counter in the origin island is also delayed. I hope they will fix all of this in the next stable update...
