Is there any app or method to easily switch between 4g and 5g?
I recently made mom switch to grapheneos on P6a with a new battery replaced as a part of the googles battery replacement program. She is having battery issues compared to her previous phone which was 4g only. its not an issue with any app or grapheneos itself but our area doesn't have a reliable 5g yet so it keeps switching between 4g and 5g. So just want to create a shortcut or something to switch to 5g when she is using the phone and on idle connection she will keep it on 4g.
I tried activity manager but for some reason its not creating a home screen shortcut and the max i found is a shortcut to .Setting$MobileNetworkActivity to open the sim settings.
Have anyone made such a setup? if so how?
