I've noticed that when my Xr which I use on Verizon is in sleep mode, the signal strength bars that show up on my car's display (through bluetooth connection to the phone) do not seem to update. Usually I will see one or 2 bars when I first start the car and drive off, but if I click on the power button on the phone, the car's display immediately goes up, very often to 5 bars. While I am not positive about this, I also think that it will stay at whatever number or bars the phone may have on it when it goes to sleep and I must therefor periodically tap the phone's power button to refresh this display in the car. Has anyone else seen this? Is it normal? I also noticed a Galaxy S10e that I used to own right before the iphone doing this as well using Tmobile. I don't think this started happening until very recently though. I never noticed it at all before about 2 weeks ago.
