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?

anyone having problems with 3g and signal bar being no signal or what not. did the *228 and fixed it but now its back to the same problem.. any idea??
Have you tried a reboot? And are you sure your mobile connection is on?
mine is doing the same thing.. goes up then down and to 1X a lot. according to the DB it is receiving good signal but just doesn't display the bars
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..

Hi Guys
lately i have upgraded my N4 from 4.3 to 4.4.2, i the network signal only shows one bar when working on 3G, when i switch to 2G a triangle occurs in the opposite side of the top screen and it says emergency calls only, in the status of the phone the received signal is 0 dbm and 99 ASU, I tried resetting my phone but it also have the same problem, also when i tried to select a network on 2G it didnot find any network.
please help is needed urgently......
thanks
Hi !
I recently purchased a S5, SM-G900F model, i'm in europe and i'm using Vodafone as a mobile carrier.
today i saw that i was only getting 1 bar and sometimes didn't show any bar at all,I went to settings and my signal strenght was at -122dbm 22 ASU, connection type as LTE, my mobile data was off.
i was afraid i had no connectivity at all and i picked another phone and i voice called my S5, i was able to make the voice call successfully and my bars went from almost none to 4-5 bars, signal strenght was at -79dbm and surprisingly it didn't drop to HSPA or UMTS.
I thought the most common behaviour for the instantly signal boost was to drop to 3G, but it didn't happen, connection type was at LTE and for long time.
I must say i was at the same place from almost an hour and it didn't boost until i made the voice call.
My question is, can a carrier be able to "keep" a mobile phone at small amount of cell towers and boost signal up with some voice call activity or mobile data traffic ?
Thanks and sorry for my poor english

1- 3G signal and LTE signal are different and separately. Some reasons that may keep your phone not drop to 3G:
a) 3G signal at that time is weaker than LTE
b) Your carrier can set a policy/algorithm of how a phone switch between 3G/LTE signal
c) Check your network settings in Settings > More networks > Mobile networks > Network mode?
2- Regarding to your question, I can say that the carrier can not have such ability.
Hello,
I have a huge problem with my Galaxy S5 SM-G900F. I bought it abroad and when I used it for the first time in my country I saw, that there is a problem with 4G/WCDMA connection. When I put my sim card to the phone and set all the preferences in mobile connection menu to "Auto" there is no possibility to call or to recieve calls (even if i saw signal strength meter showing some marks). I can only recieve and making call when I set "only 2G" option and manually select my network. But signal is also very poor.
What I have checked yet:
1. Other sim also doesn't work good.
2. After *#06# i saw my IMEI and it is the same under the battery and on the box (doesn't start from "00") so i think that it is not missed (efs folder).
3. Change firmware with KIES and ODIN for the other version - no changes. Also flash some other "modem" files with Odin with no success in better signal.
4. When im on the free air the signal strength is even at maximum level, but immidiately after going to my house - there is no signal. I saw also, that when im in the city i can connect with 2G network (only), but when im on a village there is no signal at all (even 2G...)
Do you have any ideas what can be wrong? Is this hardware failure? Maybe something with antenna? What should I do before going to gsm service center? Maybe i should change kernel and try some of the custom roms?
Thank you for your help.
regards
Mario
