Had my S21 5G on T-Mobile US for several months now. I noticed this thing is VERY slow to connect to mobile data when I'm out and about if I have wifi on if it connects at all. I can literally turn off wifi and boom, internet access full speed 5G. I've had to resort to adding a Bixby routine to turn off wifi whenever I leave the house, then turn it back on when I'm home. This works, but I shouldn't have to create a workaround to make this very basic functionality behave as expected. Has anyone else experienced this issue?
Thanks in advance.
@jperrywinters: Can you try heading to Settings > Connections > Wi-Fi > Tap the 3 dots in the top right > Advanced > Switch To Mobile Data, and toggle this option on to see if you notice an improvement?
