I'm so curious coz the Black crush issue wasn't there in my device it was very very teeny bit but after the fota updates the issue got big and now it's everywhere .
If you phone is on .58 that means your phone is already on the latest firmware.
You can check here - Go to setting => About => Software information.
For black crush we are currently looking into it.
Any new FOTA news will be shared once available. You can be updated about it in Announcement section.
Maybe 19-21 sep
