[Q] Signals Problems after 4.3 Official Update - Galaxy S 4 Q&A, Help & Troubleshooting

Hello all!
I'm from Argentina. (Excuse my poor english)
I have a full stock S4 i9500, bought to Samsung (without any carrier logo, unlocked).
During christmans night i received a notification about a new update available, i just downloaded it and installed it. Phone is now on 4.3 (Knox and other stuff are now available).
Since that update, the mobile signal is working very bad.
Every 2 or 3 hours signals completly goes off.
If i restart the phone, or turn on/off airplane mode, signals come back.
If i just leave it, takes more than 1 hour to recover signal.
This is becoming very annoying, since i uses sms a lot with my girlfriend (she don't like smartphones) and also, im loosing a lot of calls during signals fails (when signal come back, i ussually receive a lost call message).
I searched forums for this same problem, but i just found people who had stock problems, and in my case, problem become with the new update.
I want to avoid full factory reset if it possible.
I can post any screenshot if needed!

Im sorry but one solution can be make a factory reset. Only make a SD Internal backup to ur pc before do it and is all

Ok I will try it tonight and post if it worked or not

Take out the battery while the phone is on. Leave it out for 2 minutes or so and try again. :thumbup:

Nexus S total network loss.

So my girlfriend's Nexus S has been losing the entire voice and data network and going into no service mode, no biggie at first, just cycle airplane mode, then it went on to rebooting because you would select airplane mode from the power off menu but it would not check the box in the wireless settings menu.
After the reboot the box would show checked and airplane mode could be disabled and the service would resume. The the phone started getting stuck in airplane mode and not even rebooting it would bring it out the first few times, then it got to the point of resetting the phone, a wipe cache/data reset didn't fixed it. So off to T-Mobile for a new sim card. Rebooted the network immediately. And as of last night its back in full force and now not even a new sim will resurrect the network.
Have tried wiping, reflashing stock 2.3.3, new sim again, multiple resets, had to get an toggle widget to get it out of airplane mode and still a dead network, all this time the network in the *#*#4636#*#* menu showing unknown and is not able to be changed and reverts back to unknown immediately, OEM specifics settings button is greyed out and you are not able to disable the radio either.
While I'm going to call Samsung on Monday and I guess send the phone off, I worry about mine because it too does it but only once a month or so, but I do constantly have issues resurrecting the phone from airplane mode at times because the box will not be checked in the wireless settings menu but I can see the airplane instead of network bars, problem persists with reboots sometimes.
I also would like to add that even when the box is not checked in the wireless settings menu for airplane mode, if you click it it just hangs forever and will try to select but never will and stays grey like its turning everything off, but if the scren goes off its like you never tried.
Has anyone else seen this? I have seen a lot of people with data network issues or having to reboot to get voice network back but nothing as bad as I'm experiencing.
Both our phones are and have been completely stock and unmodified.
Thankfully we still have her Vibrant and in case I need to send mine in my Nexus One.

Have you tried restoring from another persons' pre-made nandroid backup?
This over-writes the radio firmware, you should give it a go!
I also found that I had problems on 2.3.3, however reverting to 2.3.2 gave me no problems!
Just contact me if you need any help restoring from a nandroid backup or finding the 2.3.2 backup files

Is that true? I am just on the verge of calling samsung. My phone won't connect to or display any available networks, and is pretty much now dumbed down to a small tablet. I've tried everything except another persons nandroid backup. I've been told to stay away from flashing another persons... but I'm really desperate.
If you could provide me with a backup, that would be awesome.
I'm having identical problem.
It was working fine yesterday, look back to it and now it's got no mobile network, nothing. Just the no bars and cross symbol. I've tried wiping dalvik cache, reflashing the radio, wiping data/factory reset, reflashing the rom, restoring with a backup (Backup of when I first rooted the phone) and still no signal. Nothing has worked..
Anyone got ideas on how to fix this issue?

Can you search for and view available networks?
This sounds like the CM7 powerwidget problem (3g/2g) I used it and I loss all network, phone process will crash every second, however if your phones are stock I can't think in anything causing it.
For CM7 you'll have to reflash and delete userdata or edit the sql database for the providers and change a value to 0, but you need root.
When I went to *#*4636.... my preferred service was "unknown" too, but now it is OK.
Try to dail:
*#*#4636#*#*
and find your network information.

Nope. Sits their 'searching' but nothing shows up.
In, *#*#4636#*#*, it gives little to no information. Just says nothing for current network and for GSM disconnects it has,
Sate: DvInactiveState
disconnected with last try
at 9:59AM
fail because No Error
And that time never changes, stays at 9:59AM.
As my above post suggested, I've tried doing a factory reset and reflashing. I don't think I use CM.. I flashed with Oxygen 2.1.6 (using it's kernel) but I restored to Oxygen rom and trinity kernel after it didn't work.

That is the EXACT same problem I have. I too was using Oxygen 2.1.6 and lost all connectivity. I've just locked my bootloader and flashed back to stock ready to send for repairs. That rom must be doing something >.>
Oh no
I didn't want to send it back D:
Anyone got some suggestions that I haven't tried?

I've been trying *everything* for last past few days. Nothing is working. That shouldn't stop you from trying though. Just stay well away from ODIN and those i9023 files, I've seen bad things.

Cheers, going to a mates place soon to see if he has anything up his sleeves to try and fix this annoying issue..
If we somehow fix it, I'll be sure to post how we did here.

Ok, it'd be great if you worked something out. I'm so glad i'm not the only person with this issue!
Anyone had any breakthroughs? *hopeful*
I wouldn't call it a breakthrough but I got somewhere!
Ended up putting a extremely thin piece of wire into the external antenna port at the back of the phone. Wasn't too keen on doing this, but my phone now has reception isn't stuck at the dreaded -113dbm.
The reception isn't good, but it's enough to send texts and have calls.
Although the area needs quite good reception for me to receive anything, and it's extremely sensitive. To get 3 bars in a place where I usually get full bars, I have to be outside. While inside it's reduced to none or 1 bar, which is enough to send/receive texts and a sort of lagging phone call (did a few tests). As mentioned before extremely sensitive. The phone seems to like it better when it's up-right. In the middle of the CBD at Brisbane I get full reception and 3G, which is fine but in the places where you usually get 2 bars, you get no signal at all, unless you're outside.
So this is hardly a fix. I will most likely be sending it to Samsung to get it actually fixed. Either that or get it fixed the same day and pay probably close to $100 so I don't have to wait 2 months waiting for Samsung to twiddle their thumbs.
Thats awesome! But I'm going to post mine off to Samsung USA tomorrow, which will take forever considering international shipping. Where could you get it fixed same-day? I'm going to try this wire thing
So it can't be a software issue, but maybe the rom overloaded the antenna and fried it or something? I'm glad we've got that far.
I've seen that nexus s has a problem like the iphone, the antenna gate. Try take the phone with the left hand looking to no touch the rear of the softkeys

Its more serious than that my friend! Thanks anyway
I got a quote from a place in Brissy called "FixMyMobile" and they said if they can fix it, it will cost $99. Although I'll get quotes from different places (if I find them) and see what they charge however I don't think I will be able to get cheaper, most likely around the same price..
So I may do that to not wait the ridiculous time it will take to get it back from Samsung.. Not sure on places in NZ though.
Yeah it seems like a hardware issue definitely. I eventually reverted the phone back to stock everything and it still happened, so that there shouts hardware issue.

Problems with mobilenetwork

Hello guys, i got my Note a week ago, and i have had som problems with the network operator signal. The problem is that phone loses signal every day, and after restart the signal comes back but after (30-40 mins) sometimes longer the signal disapears. It is very annoying. First i thought it was a problem with the sim-card but after testing it on another phone it worked just fine. I never had this kind of problem before, and i dont no what to do. My operator is (Telenor Norway). Thanks for the help.
PS: Sorry if my english is bad, i tried my best
Is it phone signal completely or just data? I have had data connection problem with my SGS2, with factory reset it went away. But I always had my basic phone service.

I had the same issue (only with data connection) and solved it choosing manually the network instead of automatic in settings. No loosing of signal in three days in a row. I hope it helps!
It is the phone signal completly, i did try to set up connection manualy but i did not help. Tho i did not try the factory reset, going to try it now and see what happens. Thanks for the both suggestions.

I have the same problem. Since the day I got my Note, I experienced both phone signal lost and 3G/2G data signal lost. Also tried factory reset and changing data to manual mode but still getting the same problem. Sometime it is the 3G/2G signal lost and some other times both phone and 3G signal lost.
The big problem here is that the moment the signal is lost, it will not automatically resumed. You never noticed it because the phone signal bars is still there running fine up and down. You thought it is okay but in fact no body can call you. You only get to notice it the time when you tried to dial a call out then only you discovered that there is no call signal. Too late - you may missed many important and urgent call !
To get the signal back, the only way is to soft reset your Note.
I get around with the above problem by installing an app called "No Signal Alert" it is free. This app will play a sound and vibrate when there is signal lost.
There's plenty of different radio for note. Try find them in the development section

[Q] Serious Signal (3G/LTE) problem (keeps loosing signal)

some background info.
I ran stock room for 3 weeks, then one morning the signal kept dying on me. it would turn on for 2 minutes then loose signal again. and they it got so bad that i couldn't even make a phone call.
so i did following:
* Reinstall room (using the settings option, and factory reset)
(still same problem)
* change new simcard
(same problem)
* then finally i sent it into service.
It came back working with stock room of course)
work done when it was in service (just a hard reset with computer, tested OK)
it now worked fine for a week, then i rooted, and flashed a G-flex room.
still works fine for 5 days.
THEN today the same damn thing happens again.
the signal drops in and out every 5 seconds, the phone gets insanely hot, and the battery drains insanely fast.
what i'v tried so far.
*Whipe dalvik cache and fix permissions.
*flash new modems. (two modems)
still same problem.
I really REALLY don't want to send it back in for another 4 weeks at the service.
Do you guys have this problem? i tried looking on google for people with same issue but nothing that relates to my model number: D_802.
can you guys helps me out?
I have the ls980 variant and get horrible reception after root. Replaced the phone and all was perfect until I rooted. Went back to stock but issue persists. Going to try and reload SW again and see what happens.

[Q] Signal issue of my Nexus 4

I'm using a Nexus 4 and I'm struggling with an insane issue. if I keep my mobile phone without using for about 2,3 hours when data or WiFi turned on, the phone is loosing signal completely and nothing can bring the signal back again except restarting the phone. Please help me to resolve this problem.
Thanks
What did you do so far? Have you done anything that could have caused this issue?
Flash your latest radio or do a factory reset and look what happes afterwards.

Once I did factory reset from the settings menu and nothing more.
Android version : 4.4.4
build number : KTU84P
can you please tell me how to install stock android again on to my mobile. please send me a proper guide if possible.
Thanks
Now I suggest you to do a factory reset again, since I am sure you havent root your phone or anything like that?
And what do you mean by 'loosing your signal'? When you turn your wifi on your mobile data will be shut off, but you still can receive calls and sms.

Yes I haven't done anything serious to the phone. the problem is once I kept my phone without using for about 2,3 hours with WiFi or MOBILE DATA switched on, the phone goes to the mode "Emergency calls only". that means I'm not receiving any calls or sms and I cannot take calls or send sms.
Anyways I have to reboot the phone to get the phone back alive. all the other functions are working properly when it happens. I think now you got the point?
Thanks

What is your radio version? You can see that in the "settings/about" section.
Android brought out a new radio with 4.4.4
It would be best to flash that, if you haven't already done so. You can find the latest radio version in the "Mako Modem collection", in this same forum. You can see the latest version in my signature.

I get you now.
But still this issue is strange since you havent flash or root or anything. What about your sim card? Already tried another one?
