Hey guys, I need your help testing something. I think I have found a way to reduce battery usage for the turn-on-by-proximity but it could just be an anomaly on the Nexus 5.
1) Install GSAM + its root companion so it can see sensor usage.
2) Install the attached KinScreen-3.2.2-beta2-d-lessprox.apk
3) Enable turn-on-by-proximity and keep-screen-on-by-proximity, time to turn off 20s
4) Plug in phone
5) Unplug phone
6) Let screen time out
7) Wait 1min
8) Turn screen on and immediately check KinScreen app usage in GSAM, note down how long proximity sensor used.
Repeat the test again but this time install KinScreen-3.2.2-beta2-d-moreprox.apk.
Post your results here!
KinScreen-3.2.2-beta2-d-moreprox.apk = 1m22s
