Samsung galaxy s4 i9500 signal drops - GSM-Forum

arvaser · 07-03-2014, 06:56

Hello, I have got samsung galaxy s4 i9500 which drops signal.. I checked that antenna is connected properly and cleaned all metal contacts on plastic frame which relates to the cellular signal. But nothing helps.
It gets signal, and while call or after few minutes it drops signal or hangs off the call.. I suspect that one of the signal components is damaged because when it gets signal it gets full signal bar.. where should I start ?
Thanks !!!

First Check following settings:
Settings---connections---more networks---mobile network--network mode ---- gsm only (if 2g) & wcdma only (if 3g)..
Check if this works for you ..

or

Your phone should typically refresh its location with the local cell towers regularly for voice and for data, if you use the code in the dialer *#105* it will tell you the last time it refreshed its location with the nearby towers, if it's greater than a few hours, there is your problem of which a replacement phone will be needed most likely, swapping the SIM card etc won't do much. You could try (if this is the case) to select manual network, choosing a different network other than your own, it'll reject, do it again with yet another network, again it'll reject, then switch back to automatic network selection again and it should force a ping to the local cell tower, however this doesn't always work.
