[Samsung Galaxy S7 Edge Guides, News, & Discussion] hp79:
1. Folder in home screen. Do they really had to add that + sign inside the folder? Galaxy S6 did not have this. Whoever designed the folder and added a big fat + sign should get their head checked out. If I have 2 icons in one folder, there's a third button with a big fat + sign wasting space and distracting the user. Sure, different luncher will fix it but at what cost ($ or battery life from other bugs). The underlying thing for the UI doesn't change though. I also tried Samsung's other UI which you can download (GoodLock app) in their own app store, but that doesn't go well with the overall UI. ---> this is fixed in Nougat.

2. Bouncing effect in S-Health and other places. When I open S-Health to record my weight and scroll through the numbers, it's very hard to get it to stop on the place I want it to be because there's some stupid elastic bouncing back kicking and fourth effect on the dial. It moves for a while even after I let it go. I really hate this behavior and wonder whoever designed it had in mind. The person responsible should do something else for a living, and not be involved in designing user interface.

3. [edit: this one is treatable by changing Setting - Applications - Default applications - Default app selection] Default apps selection. Once you select an app, that becomes the default forever. Yeah, you can reset it by clearing the default, but I wish Samsung hadn't touched this behavior so I can choose to do it once "only for this time" or keep it as default.

4. User should be able to disable Samsung Calendar without 3rd party app, root, or adb. I find Samsung Calendar worse than stock Google's Calendar app so I use Google's Calendar app. Now why do I have to keep both if I'm not using it? So much for making TouchWiz lean. These apps should be uninstallable, or at least disable-able.

5. Every time I switch Auto Sync from quick settings pull-down, I get a warning message and must confirm that I will not get notifications about some apps and battery saving blablabla. It's almost ridiculous they did not add an option such as "Do not show again". This goes same for some other switches too. I think they fixed some such as the mobile data icon, or it may be a Verizon specific thing (as I'm using 935U). In the past you get a warning something in the line of "you won't have access to YouTube videos" and such stupid popup message.

6. High Volume warning. Every time, or once you reboot, or maybe every 24 hours this warning resets and comes back. I don't listen to music that loud but sometimes depending on what you connect you need to adjust the volume over 100% level. This stupid warning shows up and it won't let you go on unless you press OK. That's really stupid. I hate you whoever designed these this way.

I currently have a Verizon S7 Edge, with the latest 935U ROM stock, non-rooted. Because I hated how TouchWiz displays icon collection of folders, I was using NovaLauncher Prime for a while but went back because Nova Launcher caused more battery drain than TouchWiz. I turned off S-Health because it also causes some battery drain, and don't like to use it because the stupid scrolling kick bouncing effect. I tried iPhone SE for couple months, and it's so much more refined but I came back to S7 Edge because the better camera (even though it's artificially over sharpened) and for the file management ability.

I thought these annoyances would be fixed over time, but no, it's been almost 10 months since I got this phone and nothing has changed.
