Love this phone. I relate it to the S10+ because that phone was amazing. Coming from Note 20Ultra. However, I’ve noticed there’s no options for VoLTE which I would like to turn off. I can tell it’s on or automatic. Dropped calls when going in and out of 4g or 5g. I noticed the mobile network in settings is very limited too. Automatic and manual. No global options. Also, I think this is related, when calling an employee, it had a pop-up saying it was an international call (which it wasn’t). Any thoughts? S21Ultra 512 snapdragon.
