On my S23 Ultra, when the setting "Switch to mobile data" is toggled on (Settings > Connections > Wi-Fi > 3 dots menu > Intelligent Wi-Fi > Switch to mobile data), the phone switches to mobile data as it should when approaching the limit of the current wi-fi network's range. But it seems to do so in a heavy-handed manner, by turning wi-fi off completely ā when returning into strong signal range of the same router, the phone fails to re-enable wi-fi. This has caused me to unexpectedly use more than twice my usual amount of mobile data for the past two months. I am not on an unlimited data plan, so this has cost me additional money that I was not expecting to have to spend, until I was able to find this obscure five-levels-deep control and disable it.
Samsung, please reprogram this setting so that it rechecks wi-fi connectivity and returns to using wi-fi data whenever throughput is adequate. If it's already supposed to do that, then please increase the frequency at which such wi-fi connectivity checks are made.
This isn't Samsung's doing. It's a bug that is normal. Just restart your phone and edit the quick panel so data is removed - then put it back on after you turn DataSaver off and it should be working well
