After my phone got updated to vs98730a a couple of days ago, I noticed its new looks plus all of these:
1. Unwelcome suggestions on top of settings that for the life of me I can't figure out how to get rid of.
2. Pre-configured notification tones in some of my apps got exchanged for other tones without my say so and can't be changed back.
3. Control notifications for some of my media apps (NOOK player) no longer remain in the notification bar after display turns off and back on.
4. Meanwhile, control notifications for other media apps (Google play music) stay on long after the actual app has been stopped and cannot be removed.
5. The new option for adjusting display size, while seemingly affecting the size of icon graphics has no effect on the amount of real estate each app icon takes on screen. Instead, the size of white border space around the graphic simply gets larger or smaller.
6. The entire list of apps under "All apps and devices" in Settings is doubled every time I select one of the apps on the list and then go back.
Overall, this has been the most disruptive upgrade ever.
