I have the same issue. My phone works fine with new modem and Wicked 10 rom but my wife exact settings and no signal. However I am in best coverage tmobile area. Its just weird. Could it be an issue with antena receiver. I checed the solution with Sim card but same thing. Anyone knows further steps? Thanks

I had issues with the same thing. I just through mine in airplane mode for a couple minutes and then brought it back and it has worked fine since. Mine would just drop signal with no warning in places that are perfectly fine for me normally. Hope it helps. Cheers!

Nexus 4 only boots if flightmode is activated

I have a strange problem with my Nexus 4 16gb. When I start or reboot the phone, the screen is black (as in the picture). I can activate the flightmode in the pull down-menu (which is still working) and reboot again (then it is working and i can enter my pin and deactivate the flight-mode after it is running). I am using the newest cm13 but the error occurred also in the stable CM12 version. At this time I had no idea that putting the phone in flightmode would solve this problem temporaly, so I installed a new ROM everytime... I already ordered a new sim-card but i do not think that this is the cause for the problem because booting without the sim-card does not solve this error.

Had this issue myself in my phone. Replaced my screen first from lg guys, didn't help. Then got the motherboard changed and works fine now. Turns out bad connection between screen and motherboard is causing the trouble

If there is any thing to worry or its just software problem.
Is it something serious.?
Should I send my device to service centre or vendor .img can correct this.?
Kindly guide me to bypass this problem or messege on my lockscreen everytime I reboot.

Something about /system/build.prop not matching /vendor/build.prop
Not sure how to fix but is fixable.

Anyone knows the solution

Nexus 5X issue with incoming calls

Hi. I got Nexus 5X and it has issue with incoming calls. It's weird because I already swap the phone and the SIM due to failure ones (same with the previous). It happens when the phone screen is locked and sometimes it cannot receive incoming calls. And caller hear a voice message from the operator that the phone is turned off. But when I unlock the phone screen it is OK. I cannot keep the screen always on
I updated the OS but still the issue persist. I thought that was SIM issue and I took another then switch the phone for another. Three of my friends got the same phone, same Android version and they have no issue (using same mobile operator). Any ideas? Is there anything I can do?

What kernel/ROM are you using?
