Random Reboots-COS 12.1. - Zuk Z1 Q&A, Help & Troubleshooting

Hi Guys,
I am new to Zuk Z1 forum. Got my Zuk a month back. I am using Jio 4g and Airtel. Eversince 15days, i am facing random reboots. Sometimes after rebooting, touch doesn't work. I think there were no random reboots before using two sims. Just screen freeze problem when double tap to wake up is on. I am not sure if using two sims is causing this problem. I am an average user. I use Jio for data and airtel for calls. Please guys, need help.

Update: Rooted my Zuk. Installed Nuclearom. No more random reboots. Infact the Jio signal strength is better on Nuclearom than COS 12.1.

[Q] Network Problems with nexus

Hi Guys,
I have a major problem here. I got nexus 4 imported to india. I use it with airtel network one of the bests here.. previously i was using win 7.8 phone without any issues. Since the time i've started using nexus 4 my gf is complaining my phone will be not reachable most of the times.. once if she sends a msg she will be able to call. and the problem i myself have seen is like sometimes when i try to call a number right next second it gets disconnected and the phone vibrates, once i tired to call a number for 15 times all the attempts. if i try after sometime it will work. the network bars will always be full. the same thing happens when i try to use 3g. I am still in stock rom. nothing much installed. shud i try a factory reset . please help guys.

In my case after 10-20 mins i will get a miss call. Looks so weird.
If somebody tried to call me most of the time they will get messages like i am not reachable. After 2-3 minutes i will get a miss call alert. And sometimes after 10-20 mins i will get a miss call.
My phone is Nexus 4, 4.4.2

Before starting, thanks for this awesome rom.
Have been using this for a week and i have observed random network disconnectivity issues. reboot solves issue temporarily but network goes down after sometime.this usually happens in SIM2 but sometimes occurs in both sims. Whenever a call is placed from any of the sims DND turns on and call gets disconnected. Hoping this to be fixed in next update.
PEACE

Phone rebooting after switching data!!!HELP

Hello guys!!!
I have a Redmi 2 model no. 2014818. I flashed the resurrection remix android N official ROM. The ROM is super smooth and has no bugs, just this rebooting problem.
So whenever I switch my data on my phone freezes for a second and reboots. It happens sometimes and sometimes it doesn't....
Also when I turn on my data sometimes nothing happens (I.e. no LTE sign in notification bar) then I need to go to APN settings and click on the + sign ( which creates a new APN ) I don't need to fill the details as I click the + sign after 2-3 seconds the LTE sign is shown, and either it works or reboots... Any help guys!!!
Thanks a lot for reading this! Any help will be appreciated
Same here
I am facing the same issue, however the problem is only with Jio, Jio sim in slot 2 doesn't work at all.
If used with slot 1, it reboots automatically some time, data disappears most of the time, then like u said, go to APN create new and data switches on, sometimes it works for few hours, sometimes it freezes and reboots.
Please help, I will be obliged.

Tried before....but didn't help ,dude.
So is the internet working in Tesla with 2nd sim? When you swapped it from 1st sim to 2nd.

That's nice! But instead of swapping reboots. It has several other types of Random Reboots.
After using Tesla for 2 days. I got 2 random reboots on 2nd day, and at that time I was listening Songs on Saavn.
And 2nd reboot happened when I was viewing WhatsApp stories.
I don't know, why it happens.

Okk....I don't play saavan. So I don't know about this.No reboot with what'sapp.
You should post log in the ROM thread.
Just use lineageos 14
Yeah, Happening with me too. Also when I place a call on VoLTE reboot occurs on custom rom and network disappears of both sim and comes back in MIUI. IDK why it is hapenning. I have also tried clean flashing stock MIUI using fastboot but it still happens. Any solution will be appreciated!

network issue

I have X01BDA. I'm using dual sims from airtel.
There seems to be some issue with network strength. Randomly, at any time of the day, both of my sims loose network completely. I recover network after 4 or 5 seconds.
I read somewhere in Asus forums that wiping cache in recovery will fix the issue. I tried that, but it didn't work.
I am attaching screenshots below. As you will see in them, airplane mode isn't turned on, otherwise it's icon will be lit up blue and there will be its icon visible on the task bar.
Both sims are working fine on other phones.
I am on stock ROM, unrooted, bootloader locked.
Same here too. I am using Jio and Airtel. Jio sim faces total signal drop occasionally most commonly while the phone is locked.
I took my Zenfone to asus service centre last weekend. they kept my phone with them for 2 hours waiting for the network drop event to occur. sadly, it didn't happen in front of them. I have showed them video proof taken with a screen recorder, but they needed to capture that event in real time to find what is causing the issue. As per them, hardware is fine, so that has been crossed out of the list.
Same problem here. Have you found solution? Thank you.
