Hi All,
I have been facing major call dropping issues on my new Samsung Galaxy S4 which i previously thought to be a problem with my new postpaid connection. but later on searching realized this to be a bug which many others are facing world wide. I couldn't find any proper solution to it other than this.
What is did is change in settings>connections>more networks>mobile network>network mode> then select gsm only. Have been using it for 2 days now and seems the issue is resolved.
Might help others.
This isn't a fix, why would I run my phone only in 2G / Edge mode... for a 3G/4G device???
There is something strange going on here, I've replicated this issue on 3 different carriers in 3 different countries (AT&T = USA, Chunghwa = Taiwan, China Unicom = China), so it's NOT a network issue. I strongly suspect that the first batch of Samsung GT-i9500's have faulty network chips, there is no other explanation as to why this is a continued issue even after all these software updates.
I had a reception problem with the I9505 too, so it's seems the hardware isn't the problem. With the newest firmware, the problem is gone.
My reception is great, only in shelters it goes down to zero bars and still didn't had any call drops.
I use an I9500 which I bought it on 13/05.

This isn't a RECEPTION issue. Randomly, throughout the day:
1) Signal will go from full bars to NIL... I'm talking airplane mode with the circle with a line through it.
2) Some time later (a few seconds to longer sometimes), the signal will come back along with 3G / H+.
It has improved with software updates, but it still happens and is completely random both time and location wise. The worse part is, this will happen sometimes in the middle of a phone call, which means you suddenly get disconnected. And yes, this happens when I'm sitting in one spot with a strong signal, so something is seriously wrong with some of these early i9500's.

I yet have to face this issue. You using i9500?
Happened to me with a self cutted microsim. Replaced it with a microsim factory made solved my problem.
I was experiencing the same issues with my i9500. It all solved when I flashed MG9 modem. Since then, I´ve never lost signal or service.

There have been several other network related issues with s4..all with different solutions. .but as of now the issue I faces was random call disconnects which is gone after selecting only gsm as im on 2g..
We can discuss all problems related to s4 network and their probable solutions in this thread... hope that might help many..

Have the same problem whit telenor in denmark. Talked to telenor about it. And they told me after some test, that the phone refuse to change from 4g to 3g when there is a incoming call.
But when i'm at the 3g /gsm network only i'm getting all incoming calls

With my device no issues perfect

It was all good with MDM.. Then I flashed the German rom and updated to MGA and then MH2. Both of them(MGA and MH2) find it hard to stick to the 3G signal and it just drains the battery. I put it to GSM only (2G) and the signal is full but the battery in my opinion is still not AS good as MDM. I sooo soooooo hope they fix it in the next update and soon!

I've had the same issue on 4 carriers: ATT, China Unicom, China Mobile (2G only), Hong Kong (forgot the carrier). This only happens on my I9500 because I cannot replicate it on my HTC One. In all instances where my I9500 craps out on me my HTC produces a strong reliable signal that never drops.
Same thing here... it happens on China Unicom, Chunghua (Taiwan), and AT&T. There is something seriously wrong with a HUGE lot of i9500's.
I have the i9505 and I only have 3 options in the network mode setting menu not 4 like I was told by other users there should be.
My network data connection drops out more often than its connected reguardless of the signal strenghth bars or also despite the about phone signal information.
I have tried a few roms all with the same problem. Im on the 3 network uk I had galaxy note before the s4 and never experienced any problems at all
It is also not area related as I have checked the coverage for the area and im in a fantastic area for cover but if I am indoors outdoors at home my dads or the shops still the same constant no internet connection error the h or h+ or 3g icon just vanishes from the too for no reason.
Can anybody at all offer any help or advice in any way in reguards to it or is it most likely I have a bad handset?
If I have the network set to auto or wcdma it is the same problem .... if I select gsm only I dont get any data internet connection at all is this right?
There is no wifi on either to cause any interferance I keep it turned off on the handset and bluetooth is off too
Thanks for any help or advice

Hmm, really bizarre that both 9500 and 9505 handsets are seeing the same phenomena. Could it be something software related then?
Question: For those that see this cutting out and returning of network signal, do you have a bunch of stuff disabled / uninstalled / removed?

Hi,
Was wondering if anyone got bad reception with their phone. I tried 3 different carriers since I had my ideos, in neither of them I ever had very reliable reception and lately the problem is getting worse. I'm running aurora 4.1a and I loose reception all the time, and the battery drains so quick because it's always looking and looking. My sister, my mum and my dad all have good reception (2 of them with my old carrier and 1 with my current carrier).. I can put my dad's phone (same carrier) next to mine.. he will have full bars with 3g and I'll have no reception at all!!!!!! Then it connects and disconnects again, and so it goes... Anyone having such issues?
Thanks.

I'm having the same problem, I'm running Aurora ICS. I use to always have good reception everywhere, Then suddenly I've just been unable to. Any help would be great! If I do find out any fixes to the issue myself I will sure let you know.
Good to know that I'm not the only one! Thanks. Hope we find a fix soon.
I've fixed mine now, What I've done is I've gone into Settings > Wireless & Network > Mobile Networks, and scrolled all the way to the bottom, and simply re-registered on the network and selected Use only 2G Data. Mines now working fine with full connection everywhere. However I don't know if our problems are exactly the same, however this is what fixed mine. Sorry if this doesn't help.
I have the same issue. Mine connects to 3G and has good connection, but then it simply disconnects and moves to 2G or reconnects to 3G some time later. That happens pretty frequently and I thought it was an issue with the carrier, but now I am not sure anymore.
Blefish, that is EXACTLY what happens to me, and I tried 3 major carriers in Australia (the only 3 that have their own actual towers). Just after I posted this thread, I happened to do the same thing as IwAsBlack recommended and... so far it seems to work. I have generally better connection and I haven't seen that ugly no reception icon since! Of course, internet browsing will be generally a bit slower but then again, it's better than staring at the phone for 3 minutes until it reconnects just to open Google.
You haven't stated which model you have. I got rid of a Motorola Bravo for at U8800-51 and I have excellent performance over AT&T (US). Crystal clear even with only one bar and I have never had a dropped call.
Have the same issue on any ROM with any mobile network in Belarus. Can't use 2G as recommended above 'cos of a huge use of mobile internet for some net-radio.
Sorry for bad Eng.
Its a U8800 Q&A forum, I didn't think that I had to state the version since I have a U8800.
Yesterday I tested and kept an eye on for the whole day! The reception since changing to 2G only has been AWESOME! Only had a drop out when I was in the subway (of course!) but aisde from that, I had amazing reception not to mention.. that my phone lasted the whole day with still 15% left!! (3G on, it would have to charge it twice while I'm at work) So, it fixed my reception AND my battery problems.

FYI, Ideos X5 U8800 describes four different models.
I know it does. What I meant is that I have the Normal U8800 model, so I didn't feel like it was necessary for me to point any variant model number like PRO or 51 or H, because it's STANDARD U8800
So we can make a conclusion that U8800 does not operate well on 3G. I can't switch it myself because I want to use internet too. And I am pretty sure we can't do anything about it, no matter if the problem is in hardware or software.

Mate, if you switch to 2G you will still be able to browse the internet! It will only be a LITTLE bit slower, better than having constant disconnection!!! I constantly use the internet to sync my gmail, send free texts, browse the net and a bunch of other stuff.. works even better on 2G with constant reception, not to mention the benefit of the phone battery lasting a whole day (AND still have internet).. so switch to 2G and you will like it... still good internet only with better reception
Same issue
Having same issue when using GSM/WCDMA auto or preferred modes. works normal on GSM network only.
Even when I have no signal of 3g, gsm is working in the background.
problem arises when I have a call, 3g signal drops to minmimun, after the call phone tries to reconnect with the 3g signal but drops the GSM signal in the process.
Try this , as soon as you disconnect the call, try to call yourself from other at that instant only. Your phone will be shown unreachable because phone drops the GSM signals.

Hi All,
I have a Galaxy Note 4 SM-N910F with BTU firmware N910FXXU1ANK4 (UK) which I flashed from the older O2 UK firmware N910FXXU1ANJ4 when I bought it.
I am having problems receiving calls and making calls when 4G LTE is enabled on the phone (I get 4G signal bar). When someone calls me my phone rings and the signal bar is 3-5 bars usually and when I slide to answer the phone it seems to answer (timer starts clocking up) and I can't hear anything (sometimes for a split second) and the other person can't hear me, then the person is directly kicked to my voice mail!
If I try to make outgoing calls with 4G enabled it sometimes works but other times it sits there saying "dialling..." then after 10 second or so gives up and stops. If I do manage to call out I get terrible phone recetion breaking up and high pitched noises sometimes. Sometimes it is ok for a while talking but eventually the call drops at some stage.
If I force my phone into 2G only or 2G/3G only then the phone seems to work completely normally.
I have had multiple SIM swaps with no luck.
Samsung walk in repair centre was useless as the empolyees all appeared to be undertrained kids.
O2 was no use saying there is no transmitter faults reported in my area.
Before I try a hard reset and flashing back to the old O2 firmware and then possibly sending my phone away for repair, is there anything else that might be going on here? Has anyone else seen this or know if it is a known problem?
Cheers,
Richard.

Most mobile providers still don't support VoLTE (don't know if that is the case in UK) so your phone needs to go down to 3g/2g when phone call is received.. So maybe there is some problem between BTU and O2 firmware (I am no expert, but may be CSC related)..
I suppose your network selection on 4g/3g/2g automatic mode, not LTE (4G only)?

I only have the option of :
LTE/WCDMA/GSM (auto connect) - Have the issues with this mode
WCDMA/GSM (auto connect) - No issues in this mode
WCDMA only - not tested
GSM only - No issues in this mode.
In phone dialer hit settings. There should be a volte toggle if there is turn it off.
I don't have any issue like that. 4G turns to 3G or 2G when receiving/taking a call. May be u hav an issue with ur firmware
I've tried flashing back from the BTU UK firmware back to the original O2 UK firmware and the problem remains. I also tried a hard reset afterwards leaving the same issue.
I have noticed that the issue does occur with 3G as well as 4G but it seems to be a bit more stable. 2G seems the most stable.
I have arranged with Samsung to send my Note 4 for repair so hopefully that will resolve the issues.
I have the same problem using 4G. Sent for replacement. Waiting for feedback..
got information that warranty service did find the problem and in a week or so I will get new one
I HAVE THE SAME PROBLEM!!!! THANKS A LOT !!!!! I WAS LIKE CRAZY TRYING WHAT CAN BE WRONG WITH THIS....
In my situation i can
send and receive sms on all mods
I can call in 4g but i can't receive calls when im on 4g... - just only hire is a issue
Last time my charger when i was charging in night get burn and i think meybe form that time... i have phone 3 weeks brand new.
Recently my s7 edge appears turned off when people try to call me. Then after a while i get the text saying someone tried to call me but the phone was off (but it was actually on). No problem making calls. It's not that you can represent it, it is totally random and not too frequent but enough to annoy me.

Does anybody know if this is a hardware problem? a bug ,or is it the carriers fault :fingers-crossed:

This used to happen to me too, i think it was because of carrier and coverage, especially when 4G signal is low.
What i found helpful is keeping my device on 2G only when on Wi-Fi or don't need high speed cellular data.
I use this app to have a shortcut of 2G/3G/4G switch in notification panel, makes switching between 2G and 4G easier.

thanks for your input.
Thing is i NEVER use mobile data, it is off all the time and the apn list is empty (no profiles), i only connect using wifi. Does that still have an effect ?
I hope it is a coverage problem

It doesn't matter if you never use data, device can still connect to 3G or 4G (though in some cases an APN may be needed to connect to 4G, that depends on carrier). In your case, since you never use cellular data, you can safely set your device to 2G only. With 2G you will have better signal for sure, and it's less likely to have missed incoming calls.

I've had the same problem with a Galaxy J7 2015 also bought in the UAE.
Again not too often but enough to be annoying. I found that selecting 2G/3G without LTE improved the situation.

Hi everyone, I own this nice terminal, but I have a big problem. When I use the 2g network, since I'm in Italy and in 4g cannot receive calls, the phone has a very low signal and remains completely absent very often. I have the same problem when 4g makes the switch in 3g. Sometimes to recover the signal I have to turn the airplane on and off. It's normal? And does anyone have the same problem or can he help me? Is this a hardware problem? With a Xiaomi Redmi Note 3 Pro in I own these problems do not occur, so I rule out the problems of my network operator.

Also noticing issues with Chromecast .It fails to detect Chromecast and need to toggle airplane mode
With the 7.10.14 i didn't noticed this.
Chromecast works perfectly, also i'm not facing problem with 2/3/4G signal.
Wifi is not that great however.
I'm not going to upgrade to latest version until they don't fix this problem.

I'm in italy too but the modem, so far, worked really well for me.
I'm using vodafone and when receiving calls the signal switches back to 3g (very rarely 2g) but never faced any issue. After the call ends the phone switches back again to 3/4g in a few seconds.

Yes it seems to work good only in city center. In rural areas the signal seems very unstable and continues to switch from 4g to H and 3g.
I found a workaround but have to renounce to 4g...I put favorite network type like in the screenshot, no more call problems and data connection is more stable also if slower.
This phone has serious issues with reception. My phone shows I have 3g signal but it can never seem to connect. I think I will have to sell our return.
It might be a network issue but its a UK bought phone from xiaomi and they haven't returned my support emails.
I've changed sim, roms, firmwares. No change. My note 5 Pro keeps trooping on though.
