I've just updated to Android Q yesterday (was really excited about it), but... I saw some good and bad changes, and some of the OneUI2 features were missing.
Bad changes (hopefully will be fixed soon):
1. Camera (Selfie MP)
The highest Megapixels in Selfie are 16, w.t.f they were 25MP.
Features that should've been added, but they're not:
1. Vivid moving icons (couldn't find that feature)
2. Edge Features (its not fair to see those in A50s and A51 and not in A50)
3. And yes, A50 has the capability to record 4K, add that too.
Those will be hopefully fixed and added.
