1. Screen display timeout resets sporadically to 30 sec tho I set it for 5 min. Maybe once every couple days it sets itself back to 30 sec so I have to set to my choice again.
2. The lighted "buttons" at bottom not only turn off (tho set to always on) occasionally, but I no longer have any haptic feedback when I touch them like I used to have on KK 4.4.4 and it was a setting. I can't find any setting except in power/ power saving mode which I have turn off vibration unchecked (means it should be on) and I do not have power saving mode on anyway. This is a handy feature, especially if the lights turn off.
And I can't find any way to turn the vibration feature on.
Seems like if stuff like this is a conscious decision by the update....that it should be listed as a change so at least we know about it instead of assuming it is a bug.
