Instagram notifications are not working, neither they are showing any notification pop up nor the edge lightning. I can only know it by scrolling down the notification panel, where it shows that I have a new message/like/comment etc. Is there any fix...

Does anybode else face this issue after the latest beta update, that when the phone is kept idle while being on home screen the brightness flickers every now and then? 

Has anyone suffered from data loss of any sort after updating to One UI 2.0? 

Unable to share pictures on Whatsapp directly from the gallery.

Is there anyone else who is facing issues while playing COD mobile, Pubg or any of the similar type of games?
