Here are some of the things and solved bugs we need in the next global flyme update (INDIA)
1.FM Radio app
2.contact app bug
   (example: name a is edited to name b and now both name a &name b shows up with same mobile number) name a doesn't get deleted
3.previous cleaning day count is faulty In security app
4.personalization in settings app have no way to change fonts
5.No search function in themes app
6.meizu phone finder from play store doesn't log in
7.the playlist in music app has 'shuffle all' as default (need to change every time to play it straight in order)
8.Toolbox app needs some better changes
          8.1.compass app doesn't calibrate correctly and often shows wrong direction
9.addition of Read modes, bluelight filter, high-contrast sunlight mode and one hand mode would be better
10.Data usage for mobile data & Wi-Fi doesn't exsist!
11.Auto-brightness must be calibrated precisely.
12.super mode could be better with brightness adjustment,flashlight, and some emergency tools like the toolbox
13.new idea feature
    13.1. To capture a selfie,  the back camera's lens must be covered with a finger and when it becomes black it is sensed and triggers to capture the front camera selfie and it could be copyrighted and called as "mCapture" (similar to tapping on fingerprint sensor on back)

That's it still found.... Will update with new discoveries of bugs
Hope Meizu will fix these vital problems in the next update
Love you Meizu and flyme
