I have this strange issue in Sony Xperia U. Currently I am using 6.1.1.B.1.100 bulid ICS 4.0.4. There is no option in mobile network to select 2g or 3g or 2g/3g. All I have is
Use only 3g networks in my settings. But I managed to select 2g network from the code
*#*4636#*#* (Phone info) and select
GSM only in
Select prefferred network type.
But the problem is this when I am using 2g data( to save juice) whenever I get a missed call after that my mobile data is unavailable( I know unlike 3g in 2g you cant use data during voice call but this is after the missed call). This is not happening if I am in 3g and only for missed calls alone.
The only way I am able to use the data again is I have to enable 3g again and change back to 2g.
Is this normal? Any workaround for this? I didnt find this when I am using previous build.
