Hi there,
First of all, I ran an extensive search over google and also on XDA forums before posting this.
My S4 (I9500) is experiencing random data connection drop problem for some time now. It starts with no data transfer (upload/download arrows not being active), then connection goes from H+ to H, then to 3G, then drops, back to H and continues until I turn off and on MOBILE DATA from toggle buttons. Then it works normal for some random time, then it happens again. Sometimes an hour, sometimes after 5 minutes.
I found this thread , however trying the workaround there by entering the provided code, I get "Connection problem or invalid MMI code". So that fix is not working either. I tried to go in service mode > debug screen > nas control and change revision to Release 5, but it says NOT SUPPORT. Haven't tried the other releases since I dont want to mess with it. I am also aware that the workaround in the above thread is for S2.
When this happens, it is just mobile data, there is no problem with network signal.
Has anyone else experienced something like that on their S4s?
