4g data wont stay connected

[Todd091]

My s8+ wont stay 4g connected when I put my phone to sleep when I drive, to connect I have to turn on then off airplane mode to connect again, any active background apps to help or any ideas to keep connected, happens everytime

Any power-saving modes turned on? Does this also happen in Safe Mode? https://forums.androidcentral.com/e...ng-galaxy-s8-into-safe-mode%2F&token=ChbWzoag
