I’ve noticed a difference when I’ve turned the ram booster on on my Phone 2, but it was a rather negative one:
Device started stuttering, after clicking the volume button I had to wait for 3-5 seconds for the slider to pop-up on the screen, lock screen would become transparent and I was able to see my home screen icons before unlocking the phone and many other issues in the same manner…
Sorry, but in it’s current state this feature makes your phone worse, there should be a better governor of which apps can go to the (much slower) phone memory instead of ram, and default system apps shouldn’t be on that list!
