[Q] Galaxy S4 I9500 weak signal - Galaxy S 4 Q&A, Help & Troubleshooting

Firstly i live in Kosovo (small country in Eastern Europe) and i use IPKO Mobitel sim card.
I am having a very weak signal on my Octa variant , i did root it in the past and changed the firmwares 2-3 times and flashed CM11 but after coming to stock non-rooted 4.3 i am having poor signal always 1 bar and sometimes even 0 when im at my home. I tried flashing different modems but still same no loss or gain..

Go to Settings>More Networks>Mobile networks>Network mode and change it to gsm only. if it doesn't help then change it to wcdma only and if even that doesn't work then change to auto connect and get a new connection from a better company
Note: It takes some time to switch network mode so be patient and give it a minute or two to properly shift.

[Q] Get LTE speed on cyanogenmod running on Galaxy Sr

So I have a Galaxy S4 Sgh-i337m (Canadian version) that have a custom recovery(clockwork touch 6) and is rooted. On that phone I have cyanogenmod 10.2 and I've been trying to get an LTE speed without success. I've seen the posts that tell me to change my apn but it haven't work. Currently when I switch data on I either get 4G or H+. I made speed test and the maximum I got is 10MBPS normally it should be around 30 to 75MBPS. So can someone help me get LTE speeds here's a photo of my current APN?
Could be a bunch of issues. Is the network mode set correct? I have noticed at times it is set to 4G to save battery. I have had times after flashing a ROM not connecting to the lte towers until after making a call. Another fix is resetting to default in apn.

Unless they've added an LTE symbol...on CyanogenMod 4G means LTE.
On touchwiz when it displays 4G its pretty much H+, Samsung just likes to make it look better
However you are right...your speed tests aren't lte speeds

When you see 4G on the status bar go to settings >about device>status. Network type should say umts% for 3g, hspda% for hspa+ or lte% for LTE (The % represents a frequency). Then you'll know for sure.

Yes it means that you have lte. The reason why your dl speed is so slow could be your reception or it could be your on wifi

Having network issue with octa version, any help?

My provider only uses HSPA +/LTE, the phone always downgrades to hspa (non +) and sometimes 3g which my provider doesn't support so I loose my data connection and it sometimes takes a really long time for it to go back to the proper hspa+ that I need it to use all the time. Anybody knows if I can somehow force the phone to use hspa+ 100% of the time?
Thanks

Switch to HSPA+ only mode. Probably wont work with phone calls unless you VOIP.

You must be mixing up HSPA+ with LTE. I don't think there's a way to choose between HSPA/HSPA+/UMTS, they're all considered 3G or WCDMA (unless you're in Canada.. carriers lie here, those networks shown as 4G are actually 3G)
Sent from my SM-N900W8
Well when my phone shows 3g or hspa I cant get anything to load online, it will stay on this mode for a while sometimes and then as soon as the phone shows hspa+ everything loads perfect. Every othere phone I have bought from Bell mobility in canada show hspa+ all the time.

I just tried making a call with my Note 3 (S800) and it was able to make a call on HSPA+ on TELUS. I think either your location doesn't have good HSPA+ signal / it's overloaded or there's a problem with the phone, does it support all the 3G frequencies Bell uses?

I know, you said "switch to HSPA+ only but you may not be able to make calls." You can switch to LTE only and you will not be able to make calls. You can make calls on HSPA+.

call #9090#.

Should be tons of radio mode options. One should be HSPA+ only.
Must be the wrong code, *9090* doesn't do anything and *#9090# brings me to a service menu which has no radio settings

Bell mobility uses "UMTS/HSPA compatible on 850 and 1900 MHz bands" which is supported by the note 3, I just dont get why both my unlocked exynos note 2 (got rid of it 1 month after I bought it because of this problem) and also the exynos note 3 have this problem on bell mobility in canada.....

You can always edit data retry to a smaller number in your build.prop.
"ro.telephony.default_network" is the build.prop entry for which default network you're on. You could figure out which one of those corresponds to HSPA+ (probably through trial and error).
**edit
Oh, you may just have to flash a new modem then O.0
My N9005 is missing quite a few radios at the moment as well.

Getting ready for 4G?

HI, the three network in the UK is rolling out 4G this weekend, what rom do I need to flash my nexus 4 with to get it working ???!!....I wan't super fast lol !!!!!!!
I think it's only starting in like 3/4 cities if your lucky enough to live in one of the cities. Also nexus 4 only supports one band on 4g if your also lucky enough for three to be using the supported band.

itll work on the n4 only if its band 4 lte, and no other frequency for lte. and its not about flashing a rom, its about flashing a hybrid radi, having the right apn, and changing the phine info to lte/gsm. there are threads that explain how to do it.
Yes I live in London.....but since updating to the latest 4.3 I can no longer select 4g LTE in the service menu. How would I find out if three is using the correct band !????

for 4.3 the option is in the phone menu, . and you need to ask them what band they are using.
Yes but if I select LTE it just goes back to CDMA ....!? Goes anyone know the three 4G APN details !? What band goes it need to be to work !??? Sorry for all the questions lol

it goes back because you need to use either the .27 hybrid radio or the .33 hybrid radio. google disabled lte for 4.3, and you cant enable lte in the settings unless you are using one of the hybrid radios.

nice rationalization, but not true. the chip works great, everything works. and since switching over to lte permanently, ive been seeing 6-7 hours screen on time regularly. imagine this, when you download things it takes time for it to finish downloading, especially large files. the slower data speed, the longer it takes. the longer it takes, the more battery is wasted. on lte, i average about 30mbps download speed, so downloads finish in seconds. so less battery is wasted. i download 2gb games from the play store in about 13-18 minutes. the newer lte chips are much better on battety than the old days, better than hspa+, hspa, 3g, and 2g.
How can that be possible ? The LTE chip in the nexus 4 has no antenna or amplifier :/ hmm I'm baffled

Battery life is the same with LTE enabled. My N4 has it enabled my wife hasn't let me to it to her's yet and our battery life is the same, but my data is much faster than her's. I get LTE signal with my N4 in the same places as I do with my Galaxy Tab 2. So I would say it works perfectly fine. Yes I am on T-mobile in case anyone was wondering.
3 UK is going to use LTE band 3 and 20 only, so the nexus 4 will not support it (unless Google is going to release a Nexus 4 LTe version, which is pointless because you should get the Nexus 5 anyway.)

[Q] No 3G signal

So I just got my Note 3 SM N900 a few weeks ago. However the signal received was very weak, so I used Odin to flash a new modem (DXUBMI1, as demonstrated in this thread http://forum.xda-developers.com/showthread.php?t=2475714).
After flashing, the voice call and SMS were more stable, I constantly got -51dbm in signal strength. Yet in terms of network connection I could only connect via EDGE (2G). When rebooting, the phone could connect to HSDPA (3G) initially, but after a while, it drops 3G and turns to 2G again, hence I believe the problem is not with the service provider.
Please see the screenshots for more details. My questions are: how do I improve connectivity and are there any other better modem base band to flash on my Note 3 (I bought the phone and currently live in Vietnam).
Appreciate your help. Thanks.
Just edit out your IMEI Number from that screen shot first - keep that number to yourself always.
Do you have a case on the phone? Or a bumper?

I forced it to WCDMA only and got 3G for a while...then the signal just went out altogether. The phone signal only came back after I switched back to WCDMA/EDGE auto select.
Is there any chance this problem is hardware related?
It is possible that it is hardware yes. However. . For some bizarre reason it may be the case.. take it off and see how it performs then you can reassess

As you said that you have flashed a custom ROM and now on stock rom,
Check whether you still have the IMEI #.
Also try insterting the Sim card on another device to check if Sim working, if working then try doing a factory reset.
Also once factory reset done as go in Setting-More Networks-Mobile Networks-Access points-Reset to default.
Try the above steps and let me know if problem still persists.
Dont forget to click the Thank button:good:
