RADIO & Random disconnects from network

Been having issues with my phone where once it while it would disconnect from the network (happens daily). I live in Hong Kong and am using 3 as the network here, and am running RomAur 2.31 with PureXAudio.
(1) Has anyone had those types of issues?
(2) Are there any flashable RADIOs? (I remember updating my radio version on my previous Nexus handset, but haven't seen anything like a radio release here in the forums)
Thanks!

Yes, but not with that ROM you mention (well actually I am using 2.3), I had constant issues as you mention with only .350 ROM. Is anybody else asking the same question as you for that slight upgrade from 2.3 to 2.31?
Not aware of any other radios available for this phone, it is too new. The radios that you see around are typically created by the phone manufacturer, and as time goes on you end up with a great choice of radios to flash with notes about the good and bad people have discovered along the way.
Why did you update the Nexus radio, where you having similar issues or issues with your cellular provider?
All I can recommend is to factory reset and re-install the ROM, of course make sure you back everything up so you can restore it afterwards.

Singapore with SingTel. Disconnects from Network for no reason in a open location also and connects back itself in few seconds.

So, when you say this are you getting the X through the red network strengh indicator at the top, if not then your phone is not disconnecting from the network, just switching modes or towers

[Q] i9505 stuck out of service

Hi,
I have a weird problem with my S4.
At work I have some areas with really bad coverage so sometimes the phone can stay for a few minutes (or even say 1h) out of service.
This is all normal. The coverage sucks, the building is weird, not problem here.
The problem is that when I go outside where the signal is normally full it does not register back to the network.
Even more it does not even go to "emergency only mode". On a few occasions I arrived back home (10Km + drive) until I realized people can't call me because the phone is out of service.
What is even weirder is the fact that on some occasions, even though the (no service) (/) sign is displayed mobile data works just fine.
My previous iPhone did something similar too - it took a while for it to recover signal after exiting the coverage black spots but never more than maximum 5 minutes.
To me it looks like a radio modem issue and maybe this is aggravated by the fact that my carrier uses the same 2100MHz frequency for both Data and Voice.
I would like to know if any of you have experience anything like this or if there is some app available that can monitor what's happening.

what network and firmware you on and wich s4 variant:thumbup:

It's Europe standard i9505.
Network is Digi.Mobil Romania - but I doubt it's relevant since it can't get even emergency only (other networks).

so... any idea?

Android needs to work on it's notification. No Service and the reception bars only gauge voice coverage. You can test this out by using Service Mode to do a PS Only (data) attach instead of the standard PS + CS (voice) attach. It'll say no service, but data will be fine.
Emergency only, is when there is coverage from other operators but not yours. No service, means your way off the grid.
I've noticed the issue you describe and it's only on some firmwares. Try a newer one and see if you still have the same issue. But you might notice a drop in your battery life because your phone will be scanning all the time. If you're happy with no coverage at work, best to just turn it off and then turn it on when your outside.
Best option is to tell your operator about the lack of coverage. There's someone in charge of stats who get's beaten every time you drop a call. You'll get extra attention if you've got other businesses around you, so let them know that too.

Thanks for the reply.
I am already on the latest firmware and I noticed the same behavior on the firmware before this one.
Unfortunately I can't try out other modem versions (from other FW packages) as that would void my warranty.

but...what about reboot phone? i know isnt funny but until u find a problem u can just reboot ur phone while u are going out from ur office...or just try to enable and disable airplane mode

Of course reboot works but I am looking for a solution, not a partial workaround.
The most annoying problem is that if I forget to reboot it when I leave work it will not recover network connectivity even if I am in areas with very good coverage, areas where you would expect your phone to work.
It looks like when it decides to give up it does not try again. It is very weird that it also drops the signal from other networks (the "emergency only") even if it's well in their coverage areas. I guess I will have to switch phones... Even if this issue was present for the iPhone too it never took more than a few minutes for it to recover on its own. And I'm not an apple fan

Just to do some brain ecercise...do u keep in power save when u are out of signal ? Its possible that disable check after few tries
Sent from my GT-I9505 using xda app-developers app

It's not in power save. I only use that function in case of battery emergency.

Same problem here
Hello, I have the EXACT same problem here. I am in Argentina.
Now, I've been in the USA for a few weeks, visiting, and while my phone was roaming, I didn't have a single problem with my phone.
Since I came back, 3 days ago, I haven't had any problems in Argentina, either.
Is it possible that something got activated when the phone was registered to another company? (it was AT&T i believe)
If that's the case... maybe you can try putting a sim card of another company and see if you still have the problem?
Please let me know if you still have the same problem or if you got it solved. I would love to know something more scientific about all this.
I don't know if this is relevant, but my compass is off by about 30 degrees. Maybe my phone is defective?
THANKS FOR ALL YOUR HELP YOU CAN GIVE ME WITH THIS

Hi I have similar issue,
My phone says its out of service or no signal or no network also I checked my sim card in other phone in the same place and it is fine. The i9505 model in ireland meteor provider was running ok until deicided to give a try to another network operator, when I changed the sim card it didnt only catch up the signal from new network provider but also it refuses to catch the old network provider. Funny thing is that I am receiving 3G but no signal bars and no service sign is beeing displayed. I am running latest official BTU (UK) firmware, the phone was never rooted, altough I had to remove the simlock and instal unbranded firmware. The phone worked fine with the newest updates for a month and now I am facing this trouble.
No factory resets nor installing same radio (couple of times) have helped. Also I used odin to instal same firmware (as it has locked bootloader) so I cannot revert back to other stock firmwares, but still no joy.
hope that someone faced the same problems and describe how to solve this issue. thanks

GT i9505 weird service problem

Ever since I got this phone i never once get any service i thought maybe the bored was done for but today I went into the town area and was surprised to see 3 to 4 signal bars on it i tried making a call and it worked, even sent an text message and it worked, funny thing now when I came back home I then again have no service bars whatsoever so I went back into town to see if I would get back signal again and i did..... Went back home for the second time and now no signal again, anyone know what might be the problem, I'm on slim rom 4.4.2 baseband XXUFNA5

Do you have a bad signal inside your home? Signal inside a house can never be guaranteed as there are many factors that affect signal strength - especially indoors.

I have an S3 and I get very good signal on that at home it's just something wrong with the S4 but i just don't know what... I get not one bar on it any else where, only when I go into town area

when you connect downtown, do you know what network you are (2G, 3G, LTE)?
It might be that near your home you only have (for example) 2G, but your phone is set to search for 3G only.

So I tried different modems and I flashed stock rom twice and still no luck, any other suggestions please

I take it u can't read or u don't have a very good sense of humor eh?

We might have a very similar issue, I also don't have a solution (yet).
My phone does not connect to 3G, only 2G and LTE.
To check if you are in the same situation:
*#2263#
then play a little with the settings there... (for example try 3G only).
see if you get any positive things out of this.
(as a note: in some of the options I can connect to 3G, BUT I cannot make or receive any calls - internet is working though). You can choose a single option only (try each 2G, 3G, LTE and see what happens). However, I strongly suggest to keep a combination of 2, see the note above).

Yes, its possible. Use Odin 3.0.7 or 3.0.9 and flash DBT (German) or BTU (UK) ROM. After flashing boot it up (but don't set up) and do hard reset either from Menu or use key combos.

This is when I'm in town today, full signal

,
And now I'm out of town, what could possibly be the problem, gosh this one is hard to figure, I don't think anything is wrong with the main board

Guess I'm gonna have to change the board since no one has any ideas of my problem

The answer is in your picture of being in town. You are only connecting on EDGE. So my guess would be that you have bad coverage in that area, ie weak signal and no LTE.
Check your providers coverage map.

[Q] Mobile data problem

I've got some problems with mobile data on my Note 4. I've bought unbranded phone in shop unrelated to any mobile provider. It's Snapdragon version (N910F).
I've got prepaid service, without LTE available (if that's important). The problem is that every now and then mobile data simply stops. There is still H or H+ sign in notification bar, and upload arrow blinks. but when i try to open web page or send message through viber, wattsup it acts like there is no network. Then i have to wait for about 30 seconds or manually turn mobile data off and then on again for internet to start working again.
I've tried changing APN settings, changing network type, but the problem is still there.
I've read some similar issues with Note 3 and SGS5 users, and some problems with modem versions, but i couldn't find anything from note 4 users
And this problem is very frustrating on phone like Note 4
Is there anything else i could try?

Mate i have exact same problem

I don't know if this is relevant, if your apn settings has a proxy and port values, try to delete it and let the proxy and port be blank. I had issues previously with data getting stuck while using proxy setting.
Sent from my SM-N910C using Tapatalk

I also loose data signal and on calls people cant hear me properly.. doesny always happen. Ill try thanks

Also experiencing this with Tmobile UK.

Also have this exact same problem with the unbranded SM-N910H, H+ but no internet all of a sudden. I also sometimes lose the whole signal (Emergency Calls Only) so I have to reboot or turn airplane mode off and on to get it working again. I asked some people and they told me it's a coverage problem with the network provider. IDK if it's true.

No ahmadmob its the phone although i have n910u i have exact same problems as u!! I thinks its modem hopefully gets solved soon im in Australia using prepaid only 3g/h+

Glad it's not a carrier specific issue.
Guess I'll wait for an official fix or for other radios to become available.

I rang samsung australia few weeks ago and they had no idea than again when do they ever!? Lol so looks like we will have to wait buddy

Some common suggestions:
1- Swap the SIM card into another phone to see if the problem persists?
2- If the problem is due to Note 4, you may need to update your firmware/baseband to the latest one (if one is available, or you have to wait until Samsung release it), or try another firmware (from another model) or custom ROM.

Tried already mate sims fine updated reflashed stock rom and still same problem.. hopedully update comes soon

I just tried sim card from another carrier, and for now, everything looks fine.
I'll go ask for a new sim from my carrier, or switch my number to another one.

Sorry for digging, didn't want to make a new topic.
I'm here with the same problem. Did any of you find solution for it (other than switching to different carrier). I'm on Play in Poland and i find mobile data problematic mostly in roaming (free roaming with every carrier in Poland). For example on t-mobile or plus i find my up arrow constatnly blinking and H switching to H+ and again. Problem is even worse with 2 or less signal bars. I'm thinking of changing sim cars to new one, but on my note 2 everything works perfectly fine.

I thought I noticed a slight improvement after the final KitKat update, may have been a placebo effect though.
In general it's still bad, much worse than my HTC M7, same network, same location etc. It seems to be particularly bad when travelling at speed e.g. on the train I get full bars but only 1 arrow flickering.
Upgraded to Lollipop a couple of days ago and finally rooted, doubt this will make a difference but will be able to report during my commute tomorrow.
In summary: The HSDPA modem on my phone is rubbish.
P.S. Previous phones I've owned came with options for different modems, I'd often flash these to improve performance, where are they for the Note 4?

I think they're not available yet, at least on lollipop...

Mine is completely fixed after a few updates i get 4g+ here excellent reception

Could tell more how did you fix your problem?

All fixed!
I can confirm that after the lollipop 5.0.1 update on my SM-N910H all my mobile data problems/mobile network drop outs are solved!. 3 days without any problems now.
Edit: maybe it had something to do with Radio and it got fixed after it got updated along with the lollipop update package?

Guys, here in my country Bulgaria, many of us owners of SGN4 have the same issue and wilth Lollipop also. I have noticed that with KitKat the problem was more frequent than Lollipop but it is still there. We have tried Polish Lollipop and now the official Bulgarian Lollipop but the problem still exists. I hope somebody will tell me which ROM you have installed (oficial) so I could share it with my fellow citizens. Thank!

G900P rooting

G'Day All
Am living in Australia and I have a G900P which works but is not overly happy.
The gps is beyond useless and it generally runs rather slow.
Has been suggested that I root the thing and put different firmware on.
I used to use cyanogenmod on the s3.
Is this still a good rooting or what do people recommend?
Am I better off trying just a stock firmware?
I'm not crash hot at this thing so the simpler the better.

Hi,
Just wondering why are you using Sprint/USA version of s5 in Australia instead of SM-G900I version. As far as I know SM-G900P version works outside USA but might cause some issues with 4G/LTE or mobile data.
Anyway, if you want to stick to SM-G900P in Australia then:
1. "GPS useless" - why? doesn't work? Slow positioning?
Try updating A-GPS (Assisted GPS) data for accurate and faster positioning:
- install from Google Play the "GPS test" app
- enable "Location" in your phone
- open the app -> open three-point symbol menu in the top right -> AGPS -> Clear and update.
2. Phone "runs rather slow":
Enable Safe mode (Safe mode can help you to track down the causes of problems you may be having with your smartphone - it will temporarily disable all third-party apps which you installed) and see if your phone performs better. If yes, try to find out what app is causing your problem. If not, try fresh install of the latest stock firmware with full wipe before playing with any custom firmware.
Regards

G'Day!!!
I am running a Sprint model because I made a bad ebay purchase and I am hoping to save face and $$$ by getting the bugger to work.
I wasn't aware of the different models at the time of purchase and as I bought it from a person here in Aus I just assumed that it would be ok.
The 4G / mobile data side of the phone is great.. no worries at all.
I have just arrived home from a road trip interstate (1500kms) and had no issues at all with reception and internet.
As for the GPS issues.. I have tried all of your suggestions wit no joy.
The main issue I have is that it can take up to 15 minutes to get a lock.. if at all.. and then the best accuracy I have ever seen is 11M.
I can stick my wifes S5 g900I beside mine out in the open.. clear A-GPS etc on both and hit the go button at the same time and hers will get a lock with 3M accuracy within 15-30 seconds.. and mine will just chug away beside hers for minutes on end.
In regards to the slow issues.. I have had a quick play with safe mode and there is noticeable difference so I will get out the knife and chop out some of the apps.
I would like to try a full wipe and latest stock firmware but honestly don't know which one to install.. XAS, BST, XAR, SPR (CDMA), or VMU
Any help on that selection would be greatly appreciated.
Cheers
Nich

Hi,
After reading this:
https://www.frequencycheck.com/comp...00p-galaxy-s5-lte-a-samsung-pacific/australia
I am positively surprised that you are not having any issues with LTE/4G.
Concerning latest stock firmware it is quite tricky thing - should be compatible with the phone model and also work on your Australian carrier.
Could you tell me two things:
1. What firmware do you have currently installed (PDA/Baseband/CSC)?
2. What is your carrier in Australia?

So my concerns were correct - you are not getting LTE as Telstra LTE bands are not supported by the phone. So I assume HSPA+ works for you.
Regarding your firmware it is strange a little: you have android 5.0 installed but seems your baseband comes from a little bit newer release of the android 5.0 firmware - official stock G900PVPU1BOA6 (PDA) firmware should contain G900PVPU1BOA6 baseband/modem. It looks like somebody flashed newer modem after flashing firmware - is your flash counter/KNOX triggered already?
Anyway if you want to try fresh installation of the stock firmware try latest available one from sammobile.com compatible with your phone. To be honest I have no experience with this phone (my is SM-G900F) and even less with using it in Australia so do it at your own risk

Oh well.
I might just leave the firmware as is.
I'll just play around with removing apps
The flash counter/KNOX is still showing 0x0.
Any clues as to the GPS issues?? Or could it all be related??
Thanks so much for your help so far.

Any clues as to the GPS issues?? Or could it all be related??
Thanks so much for your help so far.

Try and play a little with your gps. Hopefully your issue is not hardware related and can be solved.
Edit: Also, (I am not pressing you) for some users upgrading firmware helped with gps issues - so it is up to you.

Many40.. I thank you very much for all your assistance so far.. very much appreciated.
I have tried that GPS Fix link you gave me and there is no change.
I think I'll just persevere with what I have and look at an upgrade the phone.
Cheers
