So I recently got my new galaxy s9 plus from a friend and its tmobile unlocked. Witch means I'm using it in my ATT service. I've tried updating my phone through the settings app but it tells me it's up to date and it's running android 9 pie. Does anyone know how to fix this. I really want to get android 10.
Hello @Luiz_246 ,
So because your device is unlocked from tmobile but using the AT&T network you may not recieve the update. You may need to go into you nearest Samsung certified facility listed below:
For Samsung Care Authorized locations near you:
I dont recommend trying to load the software on your own as you may lock you unlocked device back to Tmobile.
Hope this was helpful!
