This time OptoFidelity test patrol carried out a video playback performance comparison between Android 4.3 Jelly Bean and 4.4 KitKat with Nexus 7.
Tests were done for Nexus 7 tablets version 2012 and version 2013 both with old Android 4.3 Jelly Bean and new KitKat 4.4 operating system. The operating system was updated to both devices as an OTA (Over The Air) update by WiFi connection.
Results were interesting. According to all measures the performance of the new operating system was weaker than that of the old operating system. The best result in video playback got Nexus 7 of year 2012 with the older operating system. An interesting result from the point of view of a demanding user requiring high frame rates is that after KitKat 4.4 update the playback of a 60 fps video did not work anymore with neither of the test videos (720 p or 1080 p) in Nexus 7 of year 2013.
