4g, 3g, and 2g

in #phone7 years ago

Is there some kind of option to make my android device prefer 4g and 3g even if the signal strength is low, but also be possible to connect to 2g automatically when there is no signal for 4g and 3g.

You can adjust the settings by dialing * # * #4636# * # * (without spaces) The closest option I found was to force it to stay in only 4g and 3g, but then, I lose signal very often. I would like it to switch only when it loses connection to 4g and 3g completely.

Thank you
Please help.
