Ok. So far besides a lot of LITTLE issues, it's seeming pretty good. People are saying battery life is better, it seems but, cant be 100% yet because I have been updating apps and configuring it so I am using up the battery.
Performance is up there with 8.1 if not faster in most causes, accept when you run into a bug, the phone hangs. Over all for doing day to day tasks, I might be keeping this build, the minor issues (that were big on 10166) that I had, seem to be resolved in this build, my Pebble watch is working on it too ! As long as battery is as good as people say, it will be a keeper so far, I have not found any DEAL killers YET.
1. Lock screen when you turn on the phone wont show the time/appointments for about 3-5 seconds when the phone is turned on.
2. Notifications are hit or miss for pop ups, I will see some show for new emails etc but, if I actually look at my email, a lot more have come in than I got a notification for..
3. Store is flakey, very buggy, Crashing for no reason, hanging, and app downloads too unreasonably long (gets stuck on minor issues), it works but, sometimes will take a few tries to get something done. My phone has 5 bars of LTE and close W-FI so not my connection.
4. Android apps are hit or miss on getting internet, I tried the Bank Of America app (Android Version) and every time I get into it, it gets "No network connection", This is on random apps I have tried.
5. Random app problems are common. Sometimes clicking (pressing) on a app will look like it's doing something but, nothing will happen, sometimes takes 2-3 tries to get a app to open. I had one that was working fine and the next day, it no longer worked, asking me to "buy" or "uninstall" buy did not go anywhere.
6. Nokia drive has a problem re-routing directions, the option was to CLOSE Drive and re-open and select past places, to get back on your route.
Nice little perk, all those games/apps that were pulled from the market place, you know all those Xbox games that they Yanked.... If you owned them, you can re-download them. In fact 2 I got a refund for because I they pulled them still showed and I was able to download them...again. Need to finish up the achivements on 2 games that were killed before they update the market place
