Hello,
I have a problem with my Galaxy S4.
When the mobile lost the 3G signal, at home for exemple because the signal is poor, the mobile shows the "no signal" icon during 10-30 seconds in the status bar before switching to 2G signal.
For me it's not normal ; because when a mobile is in 3G mode, it has to listen 2G cells for a rapid switch in case of 3G poor signal.
I tested the transition 3G -> 2G with my Galaxy S2 and there is no problem with this mobile.
Anyone has the same problem with the Galaxy S4 ?
Thank you.
same happening here for many others too... please check this.. though there is no absolute solution to it..

Is your phone carrier-locked?
Because certain phones can't access 3G/4G if it's carrier-locked.
Where do you live and what service provider do you use? Try changing between service providers to see if you can access 3G/4G with one of those providers.

my phone cannot connect to a 3g networks .. first it find just 2 operators. its Called cellcom and Orange.
anyways the signal is 2g and it cause to my internet to barely work and at the top right of the device i can see a small G letter (from what ive heard it should be H+) i think its because of this 2g mode. when I disable the automatic mode it instantly searching and finding only 2g.
can someone help me with this problem is it because of the rom or what?
I'm facing these weird issues on my phone and I will break it down as follow
1. I can get signal withGSM mode and that's the only signal frequency that can use mobile data. Sometimes it fluctuates that even though you can see some signal bars, you cannot send and receive text messages or calls. When the signal is dropped it says "not registered on network".
2. When I change my network mode to WCDMA only, sometimes I do have signal but most of the time I don't have any reception and when I activate mobile data it is not connecting. No mobile data icon like H or H+ being shown beside the signal bar but with GSM it is working fine with "E" (edge) signal.
my FW version is
AP: I9505XXUGNH8
CP: I9505XXUGNH8
CSC:I9505OLBGNH2
I haven't tried using a custom rom for mobile data usage to see if this is just a FW issue. I have tried every possible way to fix this but to no avail. Is there someone who can help me to fix this?
Hi, my i9505 has dead power button so i searched on the net and i i bought a not-working i9505 motherboard.
The problem was "sometimes it doesn't connect to the cellular network".
I installed the motherboard, sim was read correctly, insert pin.
All seems fine except it has serious problem registering to the network, and when it does ( maybe 1 or 2 times every 10/15 try ) it can only work in 2g mode, so only edge connection.
When it connectes in EDGE, after a few seconds, it disconnects, i see signal bars change and i understand it's connecting to 3G or 4G. Signal bars comes, but it acts like if it doesn't know how to communicate in that mode.
Using *#00111# i can see LTE freq. which is using.
I already tried unlocking using PERSO SHA256 OFF... unuseful try
Can you help me?
P.S. I forgot to say that IMEI seems fine, efs too.
