I was using this app on my previous android device(micromax turbo a250) and was very happy with it. Now that I have moved to Redmi Note 4, I installed it on Note 4 only to find that the virtual keys do not come up. Looks like a known issue on Redmi devices. Will definitely install it if you can fix it for Redmi note 4.
Update: the "home" button does not take you back to the home page, it takes you back to a recent page. It used to work, did a new release break it? Older comment: uIse this all the time on my S5. Does what it is supposed to do. It would be nice if I could change the color of the trigger button.
The free version is still a good app, but unlike an earlier version, the call and camera defaults cannot be changed to other apps. I would prefer instant access to a screen rotator as well as a vastly superior camera app versus the stock version. This pro version will not allow for those changes. Again, the free version is still quite good, but the pro version adds nothing of importance, and is a waste of money.
This is a must have app for me. My small tablet has a drag out side panel that is hard to access because it's in a protective water/shock resistant case and my large 18 inch tablet had no drag out side panel at all. Great app.
It slowed my phone down terrible at first, but after configuring it it seems ok. Droid razr maxx, 1.2ghz dual-core processor. The back button does work without root. I believe this is jellybean only.
I've used the version that requires root for years, and this one for several months now. Very useful/helpful apps, highly recommend. This one is not quite as great as the root version, but it comes really close.
