Samsung A41 - Phone does not connect to LTE/4G

[JohnRambo]

Hello Samsung,

Im reporting a bug. 

How to replicate the problem.
When im connected to my home wifi or any wifi,  then I leave the house,  the phone does not connect to LTE/4G or Edge. 

Solutions I have tried but no success.
A) Turning off wifi.
B) Turning off mobile data and then reconnecting to mobile data.
C) Turn on Airplane mode, then turning it off again.
D) Wi-Fi calling is off.
E) Resetting the AP (access point).

I have no mobile data until I restart the phone. This is the only way for my phone will connect to LTE/4G/Edge.
That being said, I think its stupid and ridiculous that I have to constantly restart my phone just so I can connect to LTE/4G/Edge.

Model number = SM-A415F/DSN

Hi xSteveuk,   thanks for the fast reply. My settings are the same as shown in the picture you've posted,  however that didnt fix it.

Hi Pugs,  thank you as well for the fast reply.  I checked your recommendation and it is set to on.

@JohnRambo: If you head to Settings > Connections > Mobile Networks > Network Mode, is this set to LTE/3G/2G (auto connect)? If so, try selecting 3G/2G (auto connect), 3G only or 2G only to see if you're able to connect in this manner. I'd also recommend disabling the 'Switch To Mobile Data' option in your Advanced Wi-Fi Settings, and manually enabling Mobile Data when you're out of range of your router.

Dude you are the man!!! That was it.  By disabling "switch to mobile data" fixed everything. Now my phone is displaying that im connected to my wifi and the LTE. Perfect!!!  Thanks so much for taking the time to help me out.  Its time to pop a champagne bottle :)))   

Thanks again dude!!!
