    Hello all,
    Over the last month or so, I've noticed that when switching off wifi my phone will not resume using mobile data unless I restart the phone. I usually use wifi as much as possible, but when I turn it off the phone doesn't have any internet connectivity over mobile data until I restart it. I've tried resetting the network settings but it didn't help. Once I restart the phone mobile data works fine until I switch to wifi and then later try to switch back. I'm running Android 11 on a Galaxy A20. Any help or advice would be greatly appreciated.
    Ken

    I should have mentioned also that the LTE+ symbol does still show up at the top like data is connected, but I'm unable to access the internet just the same.

    Might be an issue in the carrier network?

    I figure it's better on battery life, but I could be wrong. The problem would continue to happen even if I left it on though. When I'm mobile I still need the mobile data to work and leaving wifi on or turning it off I still can't use the mobile data. The only thing that works is staying on mobile data all the time without using wifi, but I don't have unlimited mobile data so I use wifi as much as possible.

    Could be. I contacted support yesterday and they weren't much help. I probably need to re-contact and ask to escalate to tier 2 support.

    No, not using either one at the moment.

    wifi for the most part drains the battery very little. the only time it will have a drain on the system is if the wifi signal is very weak and the phone has to keep reconnecting or scanning for that wifi signal. if you have a pretty good connection, there is no need to keep turning wifi on and off. like i said every single one of my phones in the past and present, i never worry about wifi and battery life.

    it could be a software glitch. you might want to think about flashing a firmware update. you can get them from here: https://www.sammobile.com/firmwares/

    just make sure to download the correct one for your device. firmware updates are very device specific and flashing the wrong one can soft brick your phone.

    it should not wipe data, but it is a good idea to backup, if you decide to go this route.
