My S10+ is an unlocked variant that I use on AT&T. My phone is currently on Android 9. AT&T says they've pushed Android 11 already, let alone Android 10. They've said they've tried to manually push an OS update to my device, but when I try to go to software update, the device says the software is up to date. They didn't know what else to do so they've pointed me to Samsung support. Samsung said to download Smart Switch and when my device is plugged in, it should automatically detect that it is ready for an update and do the push. However, when I plug my phone in, it says:
Model name: SM-G975U, Android 9, "Your device software is up to date SGJ(ATT)"
Anybody have any ideas. I need to at least be on Android 10.
try backing up the data then do the factory data reset
if the same, have an engineer's inspection of your device
if you're from the USA, kindly message the team to arrange one
Thanks. The closest technician would be at a local Best Buy. I was thinking they may be able to push a hard firmware update. What do you think?
Mine says ATT/ATT/VZW
