1. I get an error message when I try to deny permissions saying that this version of the app was built for an older version of Android and won't work properly on my phone.The app no longer connects to CHROMECAST!! This has happened once before in the past but now it seems this glitch is back with a vengeance! Numerous people are experiencing this issue why hasn't this app been updated?!? I was using it to calibrate all my televisions mainly for the color but now I'm at a loss.

2. I thought maybe they had a database of different manufacturers to fine tune those set's advanced settings (I want to adjust my color hue, saturation and value of my Sharp Aquos).

3. At least Chromecast works so I didn't need an adapter.Works to adjust displays, but I could not get it to play any audio to make adjustments to tune my receiver or sound bar.

4. It also required permissions to pretty much everything on my phone without any good explanation as to why.GARBAGE! I didn't want to beleive the ratings, but I tried it my self and very disapionted.

5. Only colour temp and backlight made a difference.This utility is very easy to use, with test patterns and photos, and an audio narration which explains each step of the process.

6. I was able to quickly tune my cheap TV's picture and achieve a high quality result far improved from the cartoonish, default settings.

7. Samsung's permanent nav bar on their latest update meant I couldn't remove it and the photos themselves wouldn't go full screen as a result - tapping them was completely unresponsive.

8. For picture it only helps you tune aspect ratio, brightness, contrast, color and tint.

9. Apparently I do pretty well calibrating displays without the app, because I didn't have to adjustment anything other than tint.

10. If you're not good at calibrating your TV on your own, this could help you, but I wouldn't bother trying to help with audio.This app wouldn't even open.

11. I just had to use 2 phones when I got to the color/tint adjustment sections - 1 to display the test pattern on the TV via Miracast, and the other to use the red filter camera.
