Screen resolutions of Android devices

Posted by | Android |

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
N/A 800×1232 1.0 188.3295 108×166 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.
