Hi all,
Recently had issues with the new update on my A54. Software corrupted on install so my phone would not reboot. It stayed on a black screen with the Samsung Galaxy logo.
Had to get Samsung repair technician out, he said it could one of two issues:
1. Software file corruption
2. Issue with motherboard
Luckily, my software had just corrupted so he re-installed the software and now working all fine.
He said the new update has corruption issues so best for other users to wait a few months to install the software as new patches will sort the issues that so many people have been experiencing.
