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..

Just as the thread title says I would like to know if there is anyway to switch between 2g to 3g without disconnecting 3G ..my old LG optimus Droid can do that but ,In the note a pop-up error appears and 2g disconnects and 3g connects after sometime ..
It would be great if someone could help Me put and enlighten me ..I'm really in need of this sstuff. (Don't ask me why,it helps improve my 2g speed and Theron which only Indians will know(its a free 3g trick) )
P.s ..I know GSM wcdma auto mode does something similar but is highly unstable and keeps switching between 2g n 3g..
Anyone helping will be rewarded with a thanks

Hi everyone, i've a little bug .. When i'm on my 3g data, everything fine, but when i'm moving place then it switch itself to 2g because of lower signal my mobile data network just stop working, it shows that i'm on Edge (the little E next to the signal bars) but i've no internet on my mobile, i have to switch off completly my mobile network then switch it on again to make it work .. still on 2g because of low signal..
The things is that when i'm traveling in train, i'm on 3g then it switch itself to 2g, and that's very anoying because i've to switch off the data then re-enable it to continue surfing ..
Thanks in advance for your help !

Please can you try and say if it make the same ?
3G spends on the area in which you are. If that place doesn't have 3G then you will get 2G.
edge is slow as ´1990s modem´s internet, thats why is no internet

Yeah i know but you didn't understand what i wanted to tell..
Just try, when you have 3g (H) go to settings and enable 2g only, this will change your mobile network from H to E (which is normal) but when you're in E, you won't be able to have the mobile network internet, to have it again, you will have to disable mobile data, and re-enable it .. until then you won't be able to have internet ! So not even push notification ! the signal bar in quick settings will remain "orange"..
But if you disable mobile data and re-enable it , you will still be on 2g, but you will have internet ! even if it slow (because of 2g, which is normal too)
Bump..

does any one have a reason or solution to this problem ?
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.
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?
