ankit_sharma It doesn’t affect anything. Probably just android caching the previous page which has the material UI ripple effect (the black dot). So I dont mind if its ignored

i got the 3a Pro, since this Update is WIFI is just bad, it disconnects every 30 seconds when using.
Every other Device in my Network just works fine, but the 3a Pro not.
Before this update WIFI worked just fine, but now its just not useable anymore, i turned wifi off to use the phone.

Edit:
i just reset all of my WIFI settings in the Phone and it helped.
