try another modem, use ICS or JB modem , when ROM is ICS or JB , from My Android Collections

nevermind it wasnt a phone problem, just this phone doesnt like vodafone. i switched over to another carrier and now it works great

Bad Reception with this phone?

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.

Poor Signal Strength

I bought my s4 3 days ago here in Saudi Arabia. And i noticed that i am getting poor signal strength. I am using my mobile sim to connect to the internet. And before with my s3, whenever im at the office, i can get 4mb-5mb speed. But now i can barely reach 1mb speed. I tried flashing another firmware thinking it can be better but its still the same.
i just want to ask if the signal strength is a software problem which can be solved with a few updates or a custom rom, or is it a hardware problem.
Thanks

Bump

You talking about wifi signal ?

No, i dont have problem with the wifi signal. Already tried the wifi and its ok. I am talking about the signal strength of my mobile sim card. Already did a test.
I transfered my mobile sim card to a co-workers s3 and did the speed test and got 4mb speed. Then transfered the sim card again to the s4 and did a speed test again. Cant get above 1mb speed. Did this a couple of times to make sure.

replace the sim or replace the phone? its fairly new still and most people dont have that problem.

[Q] Odd LTE Signal Swap Issues

I seem to be having the strangest LTE / 4G signal issues with the S4. I get 4G fine but when i leave a 4G area it drops to H+ or if the signal on 4G is weak it drops to H / H+ during this transition i am left without any signal for seconds to minutes as it switches.
Is there any way to find out what my LTE modem version is as i know my GSM one?
I am not too sure if this switch is normal to be lost without signal as GSM > H > H+ works fine and i still have signal

Check your baseband version and try to flash through ODIN the right one for your location

how do i do this? i can only see GSM modem not LTE. i know both versions maybe different

Mate the baseband of your phone is the same for both the gsm and lte configurations of your phone. If that won't work you can still check your carriers vpn configurations to see if there are correct

**If you are having the old bootloader XXUB flash GSM_Modem_XXUEMJ5_and_LTE_Modem_XXUBMH1.tar file with odin by selecting phone.
**If you are having the new bootloader XXUD flash GSM_Modem_XXUEMJ5_and_LTE_Modem_XXUEMJ5.tar file with odin by selecting phone.
So this means that even if it says the LTE modem is different to the GSM modem you are saying that the help about the modem for GSM and LTE is in fact the same?

From my knowledge you cant flash anything you like.You need to flash the correct modem for your region.Whats the version of your bootloader and your country so i can link you the correct file

I am experiencing the same thing, the switch from H+ to 4G doesn't drop the actual signal from the network whereas from 4G to H+ the signal drops leaving me no service at all for a few seconds.
I am starting to think that this is the normal behavior because it's like this since I got the S4. Oh and I have the latest modem for my country as well if that helps.
Perhaps someone with knowledge on how the modem works can chime in?

Thanks chickentuna for your reply
Ok the 4G works perfectly fine in Hong Kong, London but as soon as i leave london and go to areas with 4G but low signal, i get the horrible loss of network until the phone does a search. I think its more network / phone related but would just need to learn to disable 4G out of the main cities.
asbanoglou thanks for trying you can flash any modem but whether or not it will work is another matter. I understand bootloader, different modems and csc i am looking for something a little more non generic. I first assumed this was the firmware / modem combo but after trying multiple ones this does not seem to be the case unless there is a long standing issue with the S4 and LTE.
As a future note to get the modem versions you dial *#1234# . More > About does not give you the full picture but thanks for those who tried to help

Regaining phone signal problems?

Anyone else having issues with the phone never regianing its phone signal after being in an area with no signal, and have to turn on flight mode and off again to get a signal very annoying.

Yes, same here

Thankfully, no. I loose signal about 30 times during the average train ride, but it picks back up nearly straight away.

Its doing my head in sometimes I can go over a day with realizing and miss texts and phone calls

Went through hell yesterday on the underground in london, my phone gets signal as soon as it picks it up, what modem/rom combo are you using?

Try to put your phone in auto select operator. No manual select operator. And after that see tahat your problem persist.

I am getting constant data drops i.e. no data icon or internet, even though my note still shows data connected from quick settings bar, where I work the signal is a bad area indoors, also at home for the same reason, my work around is to switch airplane mode on and off again to restore data connection.
I have noticed this on all the 4.4.2 kitkat variants I have tested.

using latest stock 4.4.2 when you say auto operator is are you on about lte/gsm etc auto?

I found that grabbing the latest rom for your region and then flashing that and performing a full wipe sorted my issue when I had it.
Also, make a backup in Kies as this makes it slightly less painful to do.
It sent me round the twist, but luckily it is much better now!

Same boat here

It look like modem not work best with you provider, try different modem if you can, it's still not fix and then hardware failure.
-Mine re-gain signal very quick, it's best signal compare to all of phones i current have.
