First of all I would like to thank ro all of you who keep this great forum.
It has teached me a lot about android system.
I have an DEFY +/ android 4.3.1/ kernel 18.104.22.168 AeroKernel/ Cyanogem 10.2.2014523 nightly
I need to see the cell area info in my defy+.
I know my operator broadcasts it through cell broadcast channel 50.
In Settings - Wireless & Networks (more) menu I find cell broadcast settings.
I has an option for Brazilīs channel 50 but it does not work.
I installed an appk for it (Cell Area Broadcast Info) but it did not work either.
I also installed my chip in 2 other cell phones and cell area info was ok, so the problem is in my cell phone
