I've had four replacements (bought it on release date) . First one because the camera couldn't focus. Second one because the camera made a buzzing sound whenever used. Third one because it went to crazy bootloops whenever I came home to connect to my Wifi. Fourth one because the speaker just went crazy. Now I don't have those problems but I have quite a few problems that some people over at /r/GalaxyS6 have experienced. First of all, absolutely shitty battery life. This was a constant throughout all those replacements. I live in a place with bad reception and go to school in a place with bad reception. That means 1-2 bars constantly. I get 20-45 minute screen on time with 10-20% screen brightness and 8 hour standby. Now I can actually use the phone for 3-4 hours straight if I want because the screen uses little energy. But it's the standby that fucks it up. I know bad reception takes more battery. But my old One M7 didn't have any problems with just 1 bar.

I experience regular slow ups, for example when scrolling. It's stuttery at times. This isn't acceptable for a phone this price 2015. My One M7 did have as much stutters, just a bit more. My dad's Nexus (however his new phone, LG G3 does) doesn't, my sister's Z3 doesn't and my mother's iPhone 6 sure as hell doesn't.

The phone isn't as ergonomic as my old One M7, doesn't have as good speakers and while this does have the best camera I've used in a phone I don't photograph a lot. I'm really mad I purchased this phone, it has been a downgrade in almost every front except for the screen. I have to admit this phone has a beautiful screen. It's fucking amazing. I keep thinking I could have bought a good tablet and still pocketed 300 bucks instead of buying this near useless phone because of the subpar battery. Well, well, I'm stuck for two years now.
