I've had it since February as well, and the Update went fine for me because I *always* do a Factory Reset after Version Upgrades on Android. My experience from using this platform since 2010 is such that it is pretty terrible at accepting updates - nothing like Windows Phone and iOS where you simply install the update and go on with your life. I've *always* had issues so I avoid them entirely by simply resetting the device.
Part of the reason why I'm always anxious to get the OTA is so that I can just get that over with.
That being said, I'm about ready to EDGE the phone back and get an M8. I'm starting to pay more attention to details and I'm at the point in my life where this will probably be my last "quick" upgrade. HTC has a 2 year update policy on their devices, and the Screen Insurance here so that's a good sell to me.
1. My Magazine: Why does this exist? It's useless because Flipboard is locked onto the device (Can't Disable or Uninstall) and does almost everything My Magazine does, except the parts that would waste battery (Here and Now). No Facebook Integration makes this worthless to most people given Flipboard is ON THE DEVICE. Additionally, the Swipe from Bottom gesture is probably the worst possible solution to use on a device with capacitive buttons, and the delay betweent eh Swipe and the App coming up is just sloppy (it's there, unless you were recently using the app and it's already running in the background).
2. Camera. I'd personally like a faster shutter and higher possible ISO. I also HATE that you have to go into settings to toggle on/off Burst Shots.
3. Stock Apps. Some don't look as good as they should on a Flagship that costs this much. SMS App could use a UI overhaul. Calendar App is much too busy. Some apps have Samsung Services baked into them, which rely on Samsung Account and Update Themselves if you just swipe over to see what's there. The Video Player app is a great example of this.
4. External Speak. Not good.
5. Camera Low Light Performance can be better. Smart Stabilization works well, except if they're *any* movement in the scene. Camera is prone to shake. A phone this large probably should have a Hardware Shutter Key to facilitate a better grip and limit camera shack during photography. Video recording is great, though 4K is useless to most people since most people won't have a PC that can work with it decently (you need a beastly rig to do a lot with 4K video). If you do have a PC that can handle it, though, downsizing it down to 1080p results in superior footage than the native 1080p from the phone (and many dedicated cameras).
6. Some of the Preloads are ********. PEN.UP. S Translator requires a Samsung Account Log-In, etc.
I think the device is great, but after using it for a few months I'm not sure I could recommend it. I'm definitely going to get another phone within a month. Maybe the M8, unless Apple is going to release the iPhone 6 early with a 4.7" screen (cannot wait for September and the Note 4 is out of the question since the S5 shares many of my complaints and it will likely run very similar software).
If I get the M8, I'll buy a cheap used Sprint iPhone 4S to use as a Camera when I need higher resolution shots
Those iPhones are tiny! Shouldn't be a problem!!!
