No text alert sounds on lock screen
I have the iPhone x and do not receive text alert sounds or banners when the screen is locked. Research I found if you turn the Bluetooth off, you will receive the notifications and banners. I tried, and yes, with the Bluetooth turned off, I started receiving the banners and sounds when getting texts. I do not want to keep my Bluetooth off as I have an Apple Watch also which connects via bluetooth. I also connect to my car via Bluetooth and my head phones.
How do I make my phone send alerts and sounds when the screen is locked
iPhone X, iOS 11.0.1
