I just upgraded my samsung galaxy SL to gingerbread 2.3.6 After that, everytime my data packet is automatically activated all the time. I switch off my mobile network data and lock my phone, and then switch it on again/unlock, the network data are automatically enabled. I ve noticed, that when i un-tick/deactivate "use packet data", lock my phone with power/lock button and then unlock it, this option is ticked again (= data are enabled).
Please advise.
