I am using a BlackBerry Priv, updated to the latest Android version (6.0.1). It has started to run slower and sometimes lagged. Here is a quick tip to improve the responsiveness. 1) Turn on Developer Options Settings -> About Phone -> Scroll to bottom and tap the Build Number several times. Eventually you will see "You are now a developer!" 2) Settings -> Developer Options Scroll down and turn off the following options (or set them to 0.5x) - Window animation scale - Transition animation scale - Animator duration scale This works on different Android phones: Xiaomi Note (International), Meizu m1 note (International), Xiaomi RedNote 4
