[Q] Network Issues

Greetings all at XDA Developers
I am having a very serious problem with my Galaxy Y. My phone keeps on going into Emergency Only mode intermittently. For example it will have signal when I go to bed and then when I wake up it will be on emergency only. It also happens randomly during the day and the only way to rectify the problem is to restart my phone.
I did have a custom ROM and that is where it started, I then installed another ROM and the same issue occurred. I then decided to flash my phone to stock firmware (it is still on a custom kernel) yet it is still happening.
If anyone could help on this problem it would be greatly appreciated.
Thanks

I thought of that as a possibility. It could be but I doubt it. The SIM is only about a year and a half old. I think it could have been some dodgy configuration with a custom ROM that is still somehow present

R u sure when you flashed stock Rom it was the version you had originally

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.

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

Wi-Fi problem on cm13

Hi guys, I have installed cm13 on my S5 (klte), but I am experiencing wifi drops every few seconds and with screen turned off. I' ve tried installing different modem (BOK5, POJ1) and setting a different radio frequency, but none of this worked. Can someone help me?

I'm experiencing the same issue on my S5 SM-900F, when I upgraded from cm-13.0-20151025-NIGHTLY-klte to cm-13.0-20160203-NIGHTLY-klte. I flashed with TWRP-2.8.7.0. I read on another forum about flashing with nothing higher than 2.8.6.0 so I tried to upgrade when the 0204 came out, but no change. Anything new on this?

I've solved the issue, but I don't know how. I know for sure that this particular problem is related to DHCP, so I've messed up with my router configuration and I finally solved it. I suggest you to install TWRP 3.0.0.0 and make various try with your router configuration in DHCP section, good luck!

lollipop Bluetooth problem

Good day.
Recently i had to take out of the cellar my good old Galaxy S4 to be a replacement phone for my GF.
The problem is that since i installed Lollipop stock rom, bluetooth stopped working, but wifi still works.
I have googled it for a solution, but found none. Tried to install several different Stock and AOSP rom.
Did anyone had the same problem and solved it?
Thank you.
