Been on 8.1 sense it dropped without issue except for the touch issue, phone has been smooth as butter till the last 2 weeks and has been going down hill fast. Did another factory reset without loading backup and it helped for a few days now its back to being a turd.
IE locks up, the camera is slow very slow to open, the music app is well we all know......nokia mix is laggy and slow, my notification pull down hangs and lags, SMS freezes at times as well all within the last 2 weeks. Like I said I've gone months on 8.1 without issue and a full factory reset only helps for a few days.
I used to praise this phone now it does nothing to **** me off daily add to that Microsoft's unwilling to listen to there core users (Xbox music) and the fact that Microsoft would rather waist there resources putting out apps for there competitors (Bing weather, can we get transparent tiles already?) too when they do put out an update for an app its half baked or taking away features.
Windows phone could be bad *** but Microsoft doesn't have it in them to take it to that level.
If you find Android confusing then apple and windows phone is probably better suited for you.
