i have always found solutions for every problem i have ever had with any device, which is amazing and again, thank you very much!
now i come to you with a problem i have encountered after buying my lg g2 from hong kong, and shipping it over to my country, after setting it up and doing all the nice stuff after you get a new device i started noticing a weird issue.
the mobile data seems to be working fine (it says H next to the signal bars) and web browsing is working as well. now when i try to connect my vpn on the device to listen to pandora it doesn't connect, when i try to tether wifi to my friends or to my laptop it doesn't work, even downloading simple mp3 files from various sources doesn't work. BUT downloading apps through the app store is working. although extremely slowly. now all of this happens when i try it on the mobile data, once on wifi everything is lovey dovey and i am a happy camper.
i went to the hidden menu and activated the lte/gsm/wcdma/ auto, and got a new sim card. tried different vpns and tried downloading from different sites, nothing works. i have searched for my particular problem or any variation of it on the threads here and on other site and nothing comes up.

Hello,
Do you find an issue ? I have almost the same problem. I think the problem is un baseband problem but i amn't sure !!!!

which country are you from? I think its got something to do with the firmware version or perhaps the frequency of GSM/LTE is different from where you bought it and where you're actually using it now.

Data connection not working after Kitkat update
Hi! I got a new LG G2 from Dubai through my friend. I am in India. It came with Jelly bean initially and i have updated it to kitkat 2 days before. Till the update the data connection was working fine. But after update it is not working. The data selection is on, but it is not showing any indicator in the notification bar at the top. And also no internet. I tried Airplane mode on and off, reset to factory default, restarting the phone. But nothing works. Can you please give me a solution to get this data connection work? That is the only reason why i bought this smartphone. Now that itself is not working .. Can anybody please help? I have given all the information about my phone below. Thanks!

[Q] i9505 only getting G/E in mobile data indicator

hi guys im a new android user. i bought my i9505 galaxy s4 3 weeks ago and everything is working perfectly except the mobile data. i can only connect to E/G signals with it (which doesnt really do anything because i cant even check emails). its on LTE/3G/WCDMA/GSM(automatically) setting and the APN is the correct settings with the carrier in my country(philippines). i tried my sim on a different i9505 phone and it was able to connect to 4g so i guess the carrier/sim being the problem is ruled out. i have restored to factory settings/rebooted multiple times and am still unsuccessful. the phone's IMEI is not blacklisted or banned and it is intact(dont really know what that means but it shows a long series of numbers and im not really sure its safe to post it here). My carrier also supports the frequencies listed on what the phone has. i have not installed any custom firmwares and have not re installed any official releases.
i would really appreciate it if someone can help me fix this problem. could it be a software problem or a hardware problem(praying it isn't)?
my phone specs are
GT-i9505 samsung galaxy s4
android version:4.3
baseband:i9505XXUEMJ7
kernel version: 3.4.0-1765174 [email protected]#1 tue oct15 16:14:54 KST

Note 4 exynos sm-n910k Problem please help

So I am from Canada and picked up the exynos version from a Korean seller on ebay.
Model number sm-n910K I actually have a huge problem. When wifi is turned on phone will reboot whilst in sleep mode after about 5 minutes if I turn off wifi it works fine. Note this happens even if I am not connected to a network the radio just has to be enabled. I am out of options I might rma it to the Korean seller but I think I might have to open a case with ebay, as these guys are being very difficult here is a video attached. I filmed it for 5 minutes but only recorded the last minute. http://youtu.be/ahLB0A2pCOM any help would be super appreciated thanks guys. I am at a loss whether this is software ie corrupt modem from improper driver installation at factory or just a faulty modem things I have tried already.
1. factory reset + cash wipe
2. Reinstall firmware using kies
3. turned off automatic scanning
4. turned off download booster.
The only thing that works is keeping wifi off. Any suggestions would be appreciated thanks.

Have you tried flashing with Odin?

Hey, I also have the SM N910K. What network are you using it on?

I have that version as well without that issue. Can you grab a picture of your About device specs?

Hello there i got same version SM-N910K i didn't have that issue with wifi , but i got battery drain , i live in uk and the phone keep searching for LTE- A ,

N910C with the Samsung SoC
I have the same Issue, i live in the US, I was in Malaysia and manage to get a N910C with the Samsung CPU, when I set the network to LTE/WCDM/GSM (autoconnect) it keeps serching for 4g networks, and it does not switch to lower networks even if available, which causes a huge battery drain, i had to set it down WCDM/GSM for it to get data. I did not have this issue with my note 3 which i also got in Malaysia last year, btw, the note 3 came with qualcomm cpu, and that leads me to believe there is a problem with the modem on the samsung SoC.

Hi! i found a solution where you can force your phone to go to GSM Only, WCDMA only or your preferred network type. In your dialer app type: 319712358. It will ask for a password and the password is 774632. And voila you can now choose what type of network you want to use. This will help with the battery drain.

Hi everybody..im from south korea. I have sm-n910k.
do you have any idea for rooting this phone. I cant root this phone because of bootloader is locked. Anybody help me how do i unlock bootloader?

Update to the latest 5.1.1 ROM, and follow the steps on the page. You're good to go.

Hey i was wondering if anyone could help me. I have installed a custom Rom made for N910C on my N910K and then flashed the stock kernel and modem. I was on stock marshmallow rom and the custom rom is marshmallow as well. Everything seems to be working fine except for when i make phone calls i hear weird and loud crick crick sounds and it is impossible to make phone calls. So is there any way to fix this problem??

Struggling - Everything I Do Fails ):

So.. I'm struggling..
My mom has a Galaxy S4 (My old device, I now use a Note 4). I gave it to her rooted with a custom ROM about 2 years ago from now. It's been having random problems and it's so outdated, I decided I would get her a new ROM and fix up her phone.
Backed up all her pictures, all she wanted, and got prepared to install a new ROM. I found one in the forums here called [ROM]【5.0.1】Google Play Edition 【JFLTE-GPE】 - 01-28-2015.
So I downloaded it, and using Philz recovery I wiped all data and installed the ROM.
Calling doesn't work. Try to call someone phone turns off. At full brightness the phone seems like it's at what 40% brightness would be. And I'm sure there are more little problems here and there I would encounter, but I need to get this fixed ASAP because she has work tomorrow and she NEEDS a working phone. Edit: Just noticed on the Lockscreen it also says NO SIM CARD - SPRINT
So, since this didn't work, I searched YouTube for a video on how to unbrick/unroot the Galaxy s4 back to stock, found a video, involves Odin, followed steps exactly, getting a FAIL red bar in Odin. Great.
So I Prefer her to have a working Lollipop ROM, the one I found looks great just can't get it working. Otherwise, getting her phone back to unrooted/no custom rom completely Stock Sprint galaxy S4 would be great.
LolliPop ROM > Completely Stock Sprint Galaxy S4 > Where I'm at now.
I'm not entirely sure, but I think my problem may have to do with the firmware? Really not familiar with this stuff :/
Here is the device info:
Android Version: 5.0.1
Model: GT-i9505G
Baseband Version: L720VPUEMK2
Kernel Version: 3.4.105-GoogyMax3_GE5-v1.2.7 android @Gpe #26 Fri Jan 16 23:11:58 WET 2015
Build Number: LRX22C.20150128
Please any help, need her phone fixed ASAP or I'm Dead! haha!

I've made some progress.
I now have the Calling and Texting working perfect, it does recognize a SIM card, everything involving mobile data and connection works great.
The only problem now is the Screen Brightness. The best way for me to explain it, is it's like a Normal Galaxy S4, but the brightness is limited to between 20% and 40%. Meaning, if you put a normal Galaxy S4 on 20% brightness, that's my Galaxy S4's LOWEST. And my Galaxy S4s highest is what a normal galaxy S4 would be at 40%. Completely unacceptable d:
Any suggestions?
NEVERMIND NEVERMIND NVERMND NEVERMIND SOLVED SOLVED SOLVED SOLVED SOLVED.
In settings, under display, turned off adaptive brightness. Boy do I feel stupid!

lineage-16.0-20200905-nightly - Menu button activates itself

Hi, first post here. Installed TWRP and upgraded my wifes phone to LineageOS 16. Most things are working well, but the menu key is constantly activating without a key press. I'm a networking guy by trade and phone fiddling not really my strong point. My Google Fu always seems to fail me in situations like this too.
Any ideas? There's also an issue with Bluetooth which constantly crashes if used. Do I need to raise a new thread for that?
The phone itself is a UK version, so that's also a bit confusing when there's builds offered for AT&T, Sprint, Verizon etc. Also I've not upgraded further past this nightly build. Should I try this? Am I right in that the process should be to wipe only system partition then apply the upgrade?
Cheers.
Oh if you need me to post any further details about phone or whatever just shout and I'll get on it.

Reads as you may have installed for the wrong phone model .

I don't think so. The options presented to me over at download.lineageos.org were;
Galaxy Note 3 LTE (N9005/P) hlte
Galaxy Note 3 LTE (N9008V) hltechn
Galaxy Note 3 LTE (N900K/L/S) hltekor
Galaxy Note 3 LTE (N900T/V/W8) hltetmo
The phone model number is SM-N9005 and so the specific image I installed, after a full backup and full wipe is;
lineage-16.0-20200905-nightly-hlte-signed.zip

Non xda rom suggest you go back to the source .

Is there another rom that anyone could recommend?
