The phone was sold to us as International unlocked phone in last week of february, we didn't put any SIM but once started the phone in Mumbai it didn't ask for any regional lock or sim unlock code so we were satisfied that phone is unlocked. We didn't test it with any SIM in India though. First we put the SIM in UK and as usual it didn't prompt for unlock code etc. straight we got signal on Three uk network
but signal only lasted around 1min. When I checked signal strength it kept changing and the phone gets no signal. Have been in constant touch with 3 Network in UK(london area) and they are confirming that this phone can work in UK on there network without any issue unless there is a hardware fault.
I have spent numerous hours resetting the phone/ selecting network/ trying SIMs from different provider but signal comes and goes. When its there I can make and receive calls without any problem.
Once I made a call for more than 12 mins but signal doesn't last that much anymore.
It goes like this in Mobile Network type - H --> H+ --> HSDPA then drops (with signal strenth -113dBm 0 asu) when asu is higher it works. All this happens within a minute time frame. The wifi works fine hence software updated.
Now I feel there is problem in its Antenna but I need expert advise before I send it back to India as Samsung UK refused to fix it since phone is not bought in UK (though I was ready to pay for it) but now I guess they don't have anybody in UK to repair such phones.
Please suggest to fix this issue if you or people in your network have had such issue before and how do I resolve it?
