One of the best phone's I've ever owned. Loved the camera performance, but noticed that the stock 4K mode video recording takes up a lot of space. 64GB is what you should buy and that's it.
The glass is not that hard to replace if you have to do it yourself, however you'll note that all aftermarket glass that is available for this phone is weaker than the original. Just recently updated it to Marshmallow and it runs like a champ.
