Here is what I have encountered. 1. Coming from stock ROM, I was missing popup browser. I tried installing the one available in play store. It isn't working. I enabled the allow pop up options, but it wasn't working. 2. Setting --> Settings (samsung's) --> Display --> Screen Mode (the buttons are not visible clearly) 3. Unable to turn on Air View. I was also unable to take the screen shot using S-Pen. 4. Feedback app itself is buggy, I believe. When I executed it for the first time, it asked me what kind of bug I want to report. I did. After that I never got that screen. I was always thrown off to screen where I had written my initial report, and back to home after discarding the report. 5. After snipping a portion of display using S-Pen, I didn't get the option to share it with whatsapp, which I used to get. I get option to share it using almost all the other apps, including Viber, but not Whatsapp. Not sure what's wrong. 6. Facebook isn't syncing its contacts. It shows its synced, but in contacts app, the number of contacts from facebook are 0. Other than that, whole ROM is working great. Very smooth (as good as iOS) and stable. Great looking stock apps, I am using it after quite sometime. Nice animations. Notification Panel was a tiny bit laggy, but ok for my taste. Please let me know if I was wrong in above mentioned bugs along with a solution. Thanks in advance. PS: It's my first post on the forums. Sorry if I offended anyone or broke rules.
