Screen resolutions of Android devices

Below I provided parameters of three Android phones I tested my Lines game with:

Android Version Screen Resolution Pixel Ratio DPI Screen Size
4.4? 320×496 (480×744/706) 1.5 156.89 52×80 mm
4.4? 360×592 (540×888/850) 1.5 160.19 57×94 mm
6.0 360×592 (720×1184/1136) 2.0 160.19 ~68×123 mm

Screen Resolution column contains the information in the following format: <logical resolution> (<physical resolution>/<physical height available for applications in portrait orientation>.

DPIs with ‘~’ sign are measured manually because QT (or some Android API) provides incorrect Screen Size.

The first thing we need to spend the time with is figuring out how to enable USB debugging mode on our Android device. On my ASUS Zenfone I need to go to Settings->About->Software Information and tap on Build Number 7 times, after that I have USB debugging check box in Settings->Developer Options that I should tap as well:
