[Q] LTE is not working - Galaxy S 5 Q&A, Help & Troubleshooting

Hi, I got the S5 SM-G900F few weeks ago and all the time it was trying to figure out how to turn on the LTE.
There is option for it in settings but it doesn't connect to LTE either way, so I did a little research and found something about changing band selection mode, but that didn't work for me.
I have original 5.0.0 rom. I have virtual carrier, which is using O2 network. 1800 MHz 2600 MHz 800 MHz are the only LTE bands used by this carrier in my country and I know the coverage should be fine because of my friends can use LTE with different phones on same network.
I only found one solution which I didn't try yet, because it requires rooting the phone, which I would like to avoid for a bit, because this is my first phone with android ( Sounds almost unbelievable in this age, right?) and I would like to learn to use it well enough first.
So if you guys could suggest me any possible fix, I'd be really gratefull.

Signal Strength with AT&T and Omnia 2

Does anyone know why my Omnia 2 gets weak signal strength on At&t. I rarely get the 3g network and, at most, get 1 bar. However, the internet works fine and I love the phone but don't know if I need to go to Verizon to get better reception.
Tried At&t support but, other than upgrading the sim card, they won"t do anything with a non-at&t device. And since it was bought before the phone was launched in the U.S. I can't get support from Samsung. Are there some settings on the phone that can be changed to improve reception? Any ideas would be greatly appreciated - thanks.
Here's the network specs for the phone: GSM/GPRS/EDGE 850/900/1800/1900 MHz, UMTS 850/1900 MHz, HSDPA 7.2Mbps, HSUPA5.76 Mbps

Try changing your band settings to WCDMA then 850+1900. Works great for my Touch HD T8285.
almost there - thanks
Thanks for your reply. But, after surfing the net I still can't figure out how to change these settings on the Omnia 2, ok I don't know how to do it on any phone. Is this something easily done, and if so, how?

Not sure on your phone but on mine go to settings, then phone, then band settings.
no band settings there either
Not that easy. I get phone, then settings, then the options are general, voice call, video call and message.
General sub folders are: call cost; caller id; own number; fixed dialing; auto answer; closed user group
Voice Call sub folders are: call barring, call forwarding, call waiting
Video Call - n/a
Message sub folders are call broadcast message, wap push message, voice mail, send text message options
I tried looking at the connections menu which yields:
My Internet - add a new modem; edit my proxy server; manage existing connections.
Manage existing allows you to change from media net or other connections and when you do that there are no options for changing band. Also if you try to create a new connection there is still no mention of band.

I am not sure if your phone has 850mhz, as far as I Know the omnia 2 i8000 has 900/1900/2100 compatibility and maybe that is why you are getting so weak signal,
Only the Bell Canada Omnia2 has 850mhz + 1900mhz so unless you have this one it won't work well with at&t 3G.

This is true, I have the GT I8000l version and the band settings are in the Omnia Settings/Network Settings/Band settings menu -- Mine is set to Automatic, though there are other choices including the WCDMA, GSM 900/1800 and GSM 850/1900. You must also enable HSPDA setting as well (same Network menu) and then reset your phone.
I get Great 3G+ / HSPDA speeds almost everywhere around Harrisburg, PA "EXCEPT" in my own HOME location (only Edge ) Just that I am behind a mountain so.....
Anyway, this lack of Home location 3G+ is causing me to place my Omnia 2 (Bell Canada version) up for sale as I was expecting 3G in my own home !!!! (probably going to Ebay this weekend. The phone is great though and the screen (OLED) is INCREDIBLE !!! I am running SPB mobile shell 3.0 (Lite rom installed) so phone is quite zippy without the widget mess though the original Bell rom can be reinstalled. ( I have on DVD ) Really ticked though about the lack of 3G* at home so I may be looking for HD2 or such --and settle for EDGE speed.
Thanks to XDA developers for considering and supporting some Non HTC phones such as OMNIA 2
Not true AT ALL!

I have the original Omnia II with the 1900mhz band and have not had a single problem with excellent 3G speeds in Chicago and surrounding suburbs.
I'm getting the exact same signal strengths I was getting when I had the ATT Fuze - which does have BOTH the 850 and the 1900 mhz bands.

Chicago might primarily be 1900mhz but Dallas (my home) and probably where the original poster is located is 850mhz so the i8000L from Bell would be a better choice and probably for everyone else so you could never be limited to 1900mhz.

I loved the Omnia 2 but the lack of Roms and not having xda support (not such much anymore now i guess) made me sell it and go back to my Rogers Magic. I'll probably wait for the HTC Obsession or maybe the HTC Bravo as my next phone i definitely wanna check out Windows 7 when it comes out.

can you post your network settings?
I've had pretty good reception in the NYC area on 3G for the past 6 months... until today. Now my phone can get 3G and 3g+ reception but I can't get any data over 3G anymore. When I step down to EDGE, I can get data again. iPhone users seem to be fine. Anyone else having these problems in the NYC area?

[Q] RARE no WCDMA or 3G conection at all

Hi, My name is javier, I have bought one nexus 4 8Gb orange phone, but it is sim-unlocked so I can use my MVNO ( mobile virtual operator network) But I am unable to use 3G or WCDMA band in spain.
I Know here are some problems about MVNO and 4.3 and 4.4 and 4.4.2 Android versions, but my problem is not this one. On a Vodafone SIM Card, I am unable to get internet also on this unit. The rest of the phone works flawessly, but 3G does not. I am starting to think that GSM chip is broken. But Hey 2G Networks works well no signal lost, perfectly clear voice on dialing, and constant 20kb internet data speed. No matter is an MVNO or a real operator like Vodafone.
Searching the net, i came over this:
Nexus 4 Suffering from 3G and 4.· Upgrade
And for all of you that are not going to take a deep read, let me tell, that they say there is an error on 4.3 and newer Android framework and Radio Baseband version. So people get unconsistent 3G connection. Well mine is really consistent. No conection at all never. So I think this is not my problem, although I have tried a bunch of roms even all google ones, all basebands and a couple of sims from diferent company.
Anyway, a quick fix is quoted here: Quick 3G Fix But I do not understand what is this or what I am supposed to do with that. Can someone help me with this?
And, after that, I start to look at something more, like Sim Unlocking is snot well done and 3g Band is still locked. Havent tried it with Orange sim as I do not have any. Is there any secret menu where network locks are shown?
And moreover, How can I trace what is happening to my chip? If someone has made hybrid basebands to unlock 4G, there has to be a way to track what is happening to radio basebands while they are working...and perhaps, I can gather some good info to work with...
One more thing on *#*#4636#*#* menu, I can force WCDMA or GSM or the rest options, If I use Force WCDMA, I get signal lost for ever, If only GSM or WCDMA Preferred, it has signal but only gprs internet conection. This is with ONO (MVNO). But with Vodafone, I get HSPA Conection but no internet at all.
Really annoyed with this, hope someone is able to help me with this.
Thanks to all in advance.
Nobody? well i will try to find out myself.
Anyway I have started to know something about android tracking with logcat, and would like to know if there is any way to check all the traces of the modem to check if the chip is faulty or is a driver issue and i have to learn to modify it myself. Thanks.

[Q] Is there a way to unlock the 900 mHz UMTS frequency on SGH-I337?

Bummer.
I'm in Europe, and from simple direct testing (GT-I9505 vs SGH-I337), both in the same place (away from a big city and inside a moving train), running the same carrier, I found that the GT-I9505 had absolutely no problem running HSDPA+ speeds, whereas my SGH-I337 got up to EDGE... if I was lucky.
Inside a city there's no problem seeing that lovely H+ logo on my status bar, but anywhere else I went - nothing above EDGE.
Digging further, I learned that most of Europe (including my carrier) uses the UMTS at 900 mHz frequency for H+ data speeds, and digging more, I found that the aforementioned SGH-I337 doesn't include that particular frequency at all.
The international S4 has that frequency, even T-Mobile's version has that frequency, but not the particularly nastily locked SGH-I337 (let's not mention that damned locked bootloader).
Does my phone even have the hardware capabilities to turn on that particular UMTS frequency, and if yes, how do I unlock it?
http://forum.xda-developers.com/showthread.php?t=2291589 - this method unlocks AWS (I enabled AWS, haven't tested it yet).
Edit (even before posting):
http://forum.xda-developers.com/showpost.php?p=41739237&postcount=5 - following this post, I dialed *#2263# and that menu opened. In the WCDMA section there's WCDMA 900 - will it work for my specific situation?
I guess the mods will delete this thread, but have to ask, anyway.

[Q] "Unregistered Network" after 5 days of fully working Galaxy S5

Hi everyone,
I got a new Galaxy S5 (sm-900-w8) for my birthday. The device was bought in Canada.
It got unlocked for international usage (entered the 8 digits pin-code) and it worked PERFECTLY for 5 days.
After those 5 days the device got turned off because of the battery died. Recharged it and turned it on, and suddenly I get "Unregistered network" message on my lock screen.
Tried 4 different SIM cards from 4 different providers. Still, nothing.
The device DOES recognize a network when I turn it on, but after I'm trying to make a call 2 times (and gets a "call ended" message), it goes back to "Unregistered network" message or "Emergency calls only" message.
Please note that the signal bar is full.
Any idea how I can fix this problem?
Also, I rooted the device after the 3rd day. Does it mean I don't have my warranty anymore?
Thanks.
You didn't provide enough information for us to know what is going on.
The unregistered network simply means that your phone isn't detecting a valid SIM card. First try your SIM in another unlocked phone to see if the SIM card and or your account appear to be working. If not, then contact your carrier to check your account settings or replace the SIM card if necessary.
If the SIM works in another phone but not yours then we'd like to know where you bought your phone as the number one suspect would be IMEI blacklisting. If that isn't the issue, then the first thing to try for any unexplained anomalous behaviour is to wipe the system cache from recovery mode.
If the problem persists then you need to start troubleshooting which is nearly impossible without a detailed description of your situation. You didn't even tell us any basic info e.g. what carrier you are using, whether the SIM works in another phone, what S5 model, firmware, a step by step description of the changes you made to your phone, etc.

Thanks for the answer.
Now that I know which information you need:
- I tried my SIM card on a different device (Galaxy S3). It works perfectly.
- Also, as I mentioned earlier, I tried 3 additional SIM cards, all of them works perfectly on other devices, but not with my Galaxy S5.
- The device was bought from Rogers in Canada. I talked to them, they said it isn't blacklisted.
- I already tried to wipe the system cache from the recovery menu. Didn't help either.
- I wrote the model in the previous message: SM-900-W8.
- The current carrier is Golan Telecom in Israel.
- The firmware is 4.4.2 that came with the device. Didn't have the chance to update.
The step by step description you requested:
- I rooted to device.
- I unlocked it using a code that was given to me from some kind of shop in the mall (wasn't there, my gf took care of it), but it worked perfectly.
- The device worked well for 5 days, then the battery died and after I recharged it the problem started.
- If I disconnect my battery for several minutes and connects it again, the device DOES SHOW that it is connected to the network ("GOLAN T"), but if I try to call, after several seconds it disconnects and the "Emergency calls only" or the "Unregistered SIM" message appears.
- Tried reseting it to factory settings and to wipe the device's cache from the recovery menu. Didn't help.

Bingo. That is why you can never have too much information when troubleshooting.
Until proven otherwise, your problem is almost certain to be the fact that you are not using the S5 model that your carrier expects. Most Israeli carriers use the 900F model and you bought a 900W8 instead. The W8 is not intended for use in the middle east and has a different spectrum allocation than the 900F model.
Ask your carrier to spell out exactly what frequency bands they use in their network. More than likely one or more bands is missing in the W8 and that will be your problem. Other possibilities include region locking, which is Samsung trying to block you from doing exactly what you are attempting.. buying a phone in one country and using it elsewhere. You should also check the carrier blacklist (this is not the same as the IMEI blacklist).. but rather a roaming block that may be interfering because you are using the phone in a country that it wasn't intended for.
And possibly.. although unlikely, your carrier may block foreign IMEI numbers. You'd have to ask your carrier if they have any restrictions regarding handsets that customers purchase from third party sources.
There is one possible anomaly here. Your first post said that your phone worked for 5 days before failing. Was that 5 days in Canada or Israel? If Israel, that makes the last possibility more likely, although it could also be attributed to other factors.
Even though your SIM card working on a different handset tells us that there is some incompatibility between your phone and your carrier's network, you may still want to open a technical support ticket. It's possible that your carrier support department may have run into this issue before and have an expedient solution. Perhaps something as simple as needing to manually add the correct APN info.

Hey, thanks again for the answer.
The 5 days that I mentioned (when the phoned worked perfectly) were in Israel. The phone was never used in Canada, so do you think the frequency issue is still likely?
I already talked to my carrier, and tell you the truth, the carrier doesn't sell any devices (at all), so I really doubt they will block my device.
Again, they didn't even knew I changed it. They checked it out when I called them, and they said they never block any device - I did mentioned that the device was from Canada.
And again: I tried SIM cards from 4 different carriers (except for Golan Telecom, I tried Cellcom, YouPhone and Hot Mobile).
Is there any other information that you need me to provide?
Just tell me what and I'll give you the information you need.

BTW, I've checked the APN info, but it's just needed for MMS and for the 3G internet.
Tried with that configuration and without, it didn't matter.
Oh! I just remembered one more thing.
I succeeded browsing the internet VERY slowly, several times (it wasn't WIFI of course). Super-weird.

That datum confuses the issue, but yes the ostensibly missing frequency bands are still the most likely culprit. Particularly since you tried multiple known good SIM cards in your phone. Something is conflicting between your phone and your local networks. And by far the most obvious cause is the spectrum allocation. Meaning that it may work erratically (or for five days) but can fail when the system tries to use the missing band(s).
Less likely, your local carriers may be conflicting with something else in the phone. Or it could be a random hardware failure, although that is very improbable. If it was a hardware failure, I'd think more in terms of a damaged SIM slot than semiconductor failure. Troubleshooting is all about ruling out possibilities and looking for patterns. So you need to work though the list of the most obvious candidates. For a start:
- Find out what frequency bands your carrier uses. And compare that to the W8 specs (Google search: sm-g900w8 specs)
- Check the roaming /region lock blacklist i.e. /system/csc/customer.xml and confirm that your Israeli carriers are not listed in that file.
- Find out what your carrier's APN information is and confirm that your phone has the same settings.
If you don't find a solution there, you should wipe your system cache from recovery mode and do a factory data reset. And failing that even write a full stock firmware image to the phone again - the latest firmware available just to cover the slight possibility that it could be a firmware bug.
And while not a panacea, you should still open a support ticket with your carrier. Don't get them mired in a long set of I've already tried this and this and this.. Just tell them that your phone worked fine for 5 days and now gives an "unregistered network" error. And that your SIM continues to work in other handsets. That should spur them to look into your account settings and hopefully identify anything that may be conflicting with your W8 phone.
And as a last resort, I guess claim it under warranty. If you used Towel root your warranty is probably still intact. You can boot to download mode or install the Phone Info app to find out your Knox flag status. If it is 0x0, then you only need to restore the stock firmware and you should be fine with respect to warranty.
If your Knox flag is 0x1 for any reason, Samsung will raise a stink about it. A lot of carriers don't care about Knox with respect to warranties thought. I don't know Roger's position on that point but in any event don't make a warranty claim directly with Samsung if you have a 0x1 flag. Make a warranty claim through your carrier (presumably Rogers) instead.

Nope, not really all that weird. It sounds more and more like you are missing a key GSM frequency band.
Nevertheless you should check all of the possible culprits.
Good luck

Quick search using google:
According to this: http://www.worldtimezone.com/gsm.html, Golan uses 3G 2100 frequency, which is supported according to this: http://www.samsung.com/ca/support/model/SM-G900WZKABMC (tech specs are expendable at the bottom).
Other frequencies seems to be supported as well. Actually, all the frequencies of the Israeli carriers seems to be supported.
If your handset supports all active frequencies that is great news, but you still need to work through the rest of the list of things to look into. Also, if you know anyone local with an unlocked 900F S5 phone, try your SIM in their phone.
Specs for Israeli 900F and Canadian 900W8, differences in bold.
You need to confirm that your carrier does not use the missing frequencies i.e. B8 (3G GSM 900) & B20 (LTE 800)
SM-G900F
2G GSM B8 (GSM 850MHz), B10 (E-GSM 900MHz), B13 (DCS 1800MHz), B14 (PCS 1900MHz)
3G UMTS B1 (IMT 2100MHz), B2 (PCS 1900MHz), B5 (US 850MHz Cellular), B8 (GSM 900MHz)
4G LTE B1(2100), B2(1900), B3(1800), B5(850), B7(2600), B8(900), B20(800)
SM-G900W8
2G GSM B8 (GSM 850 MHz), B10 (E-GSM 900 MHz), B13 (DCS 1800 MHz), B14 (PCS 1900 MHz)
3G UMTS B1 (IMT 2100 MHz), B2 (PCS 1900 MHz), B4 (AWS), B5 (US 850 MHz Cellular)
4G LTE B1 (2100), B2 (1900), B3 (1800), B4 (AWS), B5 (850), B7 (2600), B8 (900), B17 (700)

OP this may sound ridiculous but go into your System>About Phone and check for your imei... you can also do *#06# hit send on your dial pad...
If your imei shows 000 or something weird other than the one that is printed on the sticker under the battery or box then you have a defective phone. I usually see this Unregister Network thing happen to quite a few Samsungs over the years, starting with the S2. You may have done something and caused the IMEI to get lost/wiped in the EFS.
The best thing to do in this case is you have to have the IMEI rewritten. This may be really easy if there is still an EFS backup on the phone or if it is still accessible. Otherwise at the time of writing this I think both the Octopus/Z3X cannot write IMEI on the S5 so taking it to repair shop can be pointless until it does.
Worse case scenario is your actual baseband chip is screwed.
Anyway, check to see if your imei is there. No IMEI = network cannot register you on as you device doesn't exist.

You need to confirm that your carrier does not use the missing frequencies i.e. B8 (3G GSM 900) & B20 (LTE 800)
SM-G900F
2G GSM B8 (GSM 850MHz), B10 (E-GSM 900MHz), B13 (DCS 1800MHz), B14 (PCS 1900MHz)
3G UMTS B1 (IMT 2100MHz), B2 (PCS 1900MHz), B5 (US 850MHz Cellular), B8 (GSM 900MHz)
4G LTE B1(2100), B2(1900), B3(1800), B5(850), B7(2600), B8(900), B20(800)
SM-G900W8
2G GSM B8 (GSM 850 MHz), B10 (E-GSM 900 MHz), B13 (DCS 1800 MHz), B14 (PCS 1900 MHz)
3G UMTS B1 (IMT 2100 MHz), B2 (PCS 1900 MHz), B4 (AWS), B5 (US 850 MHz Cellular)
4G LTE B1 (2100), B2 (1900), B3 (1800), B4 (AWS), B5 (850), B7 (2600), B8 (900), B17 (700)

In isreal:
2G GSM: B8 (GSM 850MHz), B10 (E-GSM 900MHz), B13 (DCS 1800MHz).
3G UMTS: B1 (IMT 2100MHz), B5 (US 850MHz Cellular), B8 (GSM 900MHz)
4G LTE: B3(1800), Soon will use 2600Mhz too B7(2600) .
4g- Only before few week 4G open, but only 5Mhz of 1800Mhz are in use for now.
So only 900Mhz in 3G are missing..(Not all carroir useing this Fq...)

Meizu MX5 no 4G network capabilities

Hello,
I have been using my Meizu MX5 for about two months now without the 4G network working. I have recently updated to the latest firmware and I am currently running Flyme OS 4.5.2.7A and that has not solved any issues either.
I have checked that the phone settings are configured properly.
Network Mode is set to "4G First".
The phone is pending between, H-, H and H+ connection (3G I believe?)
I have checked with my provider and these are the following frequencies which should be providing 4G in my country (Sweden) for the provider:
800Mhz, 900MHz, 1800MHz, 2600MHz
Other providers have the same frequencies as well.
I have also gotten two new SIM-Cards during this period of time without it solving any issues. I have tried the SIM cards in some other phones and they get 4G connection without any issues.
I have been in contact with Meizu customer support in China and after some random troubleshooting of factory resetting and reinstalling the same firmware on the phone without solving anything.
They have also provided me information regarding the different bands/frequencies which the phone operates on:
GSM/GPRS/EDGE (900/1800/1900MHz)
WCDMA/HSPA+: Band 1/2/8 (900/2100MHz)
FDD LTE: Band 1/3 (1800/2100MHz)
TD-SCDMA: Band 34/39 (no freqency specified)
TD-LTE: Band 38/39/40/41 (no frequency specified)
I am not 100% sure on how this works but according to the information I am given, the phone and my provider share at least one frequency for the 4G network and therefore I do not understand why it is not working.
I am sure that it is software related and thus I won't send my phone back to China (4-8 weeks delivery time and all expenses has to be paid by me) for them to troubleshoot.
Anyone here who has knowledge which could give me an answer?
Kind regards,
Martin
Hi mate.
I had this problem but upgraded to new firmware late last night and it came on. Thankfully!
Give it a try
Hi,
I have checked the upgrade app on the phone and it says I have the latest firmware.
Which firmware version are you running?
Kind regards,
Martin
Maybe it is an APN related problem. Look if you have the same data as in the other phones that 4G works

Hi iicc,
Thank you for the reply.
I have checked the APN settings about four-five times and I can't find any inconsistencies. I have even crosschecked it with a support technician from my provider.
The only things I can think of is either my anntenna being gimped, that the firmware is not properly developed or that somehow there's trash in my system and that my phone maybe needs a complete wipe and reinstallation.
After the upgrade to firmware 4.5.2.7A the phone does not even hint on trying to connect to 4G. Pre-upgrade it atleast connected to 4G for about 5 seconds and then went down to 3G.
Kind regards,
Martin

And have you tried to factory data reset the phone?

Let me try to come up with something that might be your problem. If you are using 3 as your mobile provider then they use FDD-LTE band 7 & 20 none of which are supported by the MX5 and 3 are also using TDD-LTE band 38 which is supported by the MX5, but might not be available in your area.
If you are on Net4Mobility then they use FDD-LTE 3,7,8 & 20 of which only 3 is supported, so it could that in your area there is no coverage with band 3.
If you are on Telia, the story is pretty much the same as Net4Mobility as they use FDD-LTE 3,7 & 20.
In order to get more from your phone. You can open up google and search for 'meizifan eu' and go to the website. They have a pretty good description of how you install the international version of FlyMe on your MX5, the international version is called 4.5.2.7i. I believe it activates some other FDD-LTE and TDD-LTE bands.
1800Mhz band is a short range, higher bandwidth frequency which usually is less common and given that it has a short range it most likely isn't available in your area.

Thank you for the reply nasty_suicide!
I am using Comviq Tele2 as provider, which should use the Telia net.
This is what I believe as well, but I really thought there was no way to flash the international version onto the phone and was about to abandon ship by buying a new phone yet again.
I will try to install the International version as soon as I have time to follow through the steps. I have found the guide on Meizufans.
Once I have installed the international version I'll let everyone know the outcome.
Kind regards,
Martin
Hi Hawdes,
I've exactly the same problem as you do, please post back once you instal I version. I was planning to do so but since I already have everything installed I didn't want to go through trouble for nothing.
What were the results of this? Is it true that firmware can affect the signal received?
upgraded to the latest firmware yet?

What about in Samsung galaxy s7 version of Flyme OS?? I cannot see 4G option.
