nikolaevra, Jun 8, 2016 : With the update coming to OP2 devices very soon, you might be wondering if it's worth upgrading. Well, wonder no longer because I've got you covered with my review of the new OS. First of all, it's 1.1 GB, so better make some space on your phone. Now, what has improved: 1) Finger print scanner is like insanely flash-like fast now. 2) So much less lag throughout the system. (Examples: opening recent menu is fast, typing never seems to lag and buttons don't stick, no lag opening notification panel at all) 3) Obviously, we got Google Now on tap, which is pretty sick 4) OMFG, AMBIENT DISPLAY IS AWESOME 5) It's a Marshmallow thing, but the sharing options are significantly better now. UPDATE: Android Doze is insane. When you look at the battery usage graph, the slope of battery drain is significantly smaller (if that makes sense?). In other words, Doze is working really well. Sorry for ghetto editing, wanted to put it out sooner, had to edit in Ubuntu I will be posting more screenshots soon, just let me kill the battery first I will be updating the post with things such as battery life and other miscellaneous changes. For now, if you have any questions about OS, feel free to ask, and I'll do my best to answer.
