[Q] Nexus 5 (KitKat 4.4.2) is Stuck in Safe Mode

After I restarted my Nexus 5 (Kitkat 4.4.2) phone after a flight yesterday, it only starts in "Safe Mode."

On the boot screen, I cannot select any other option by hitting "volume down" button (default selection is 1st in the list). Also, once the phone starts, the "volume down" button doesn't work. Therefore, I am thinking my "volume up" button is stuck. Which explains why the phone doesn't start in normal mode and gives me the boot screen (On/off switch with volume-up button).

To my surprise, once my phone starts I noticed following behavior.
(1) Pressed volume up button. On screen volume slider shows up and volume goes to max.
(2) I decreased the volume via "on screen" slider (not through volume down button).
(3) If volume up button was "stuck," as I thought, as soon as I let go the slider on the screen, volume should start increasing again. But it doesn't. Therefore, I am guessing, it might not be a button hardware issue.

Note: I tried the aforementioned three steps with my wife's Nexus 5 and on Nexus 7 by continuously holding down the volume up button. In step-3, as I expect, volume does start going up, as soon as I release the slider on screen.

Any help is appreciated. Thank you very much.

I would test this by (backing up ROM first) flashing another ROM (maybe stock based) and test to see if issue persists. If not problem anymore, then it was ROM/software issue, try reflashing stock/ROM currently on to fix issue. If you flash and problem persists, then probably a hardware issue that may have to be returned for exchange through Google.

I did the factory reset. Unfortunately, it did not work.
Since I will not be able to select options via volume up/down button on the Bootloader screen, I am not sure whether I can flash another ROM.

Try Flashify or Mobile Odin to flash a touch based recovery (ie. clockworkmod with touch option .img file from website or TWRP) and boot to recovery via the app (ie CWM app boot to recovery or the goo manager app, which ever recovery you install). That should allow you to flash and avoid the need to use the volume keys.

This sounded a bit out of my comfort zone, so I called Google and explained the issue. Google is replacing my phone.

The call took less than 3 minutes. I received an email within 2 minutes with a link to place a replacement order, along with documents for returning old phone. Since I can return my phone after I receive a new one, I will not have any downtime.

Thank you for your help, RevelationOmega.

I had the same problem with my Nexus 5 and while looking for a solution stumbled on this post. I took a flight from sea level to a place about 2km above sea level and the volume bar on the phone got stuck. This seemed to lead to the phone automatically going into safe mode, with no way of getting out. On the flight back the start button seemed to also get stuck. I thought I would have to replace the phone cause in my experience trying to get these things fixed is not worth the effort. Much to my relief a few hours after I returned home the phone fixed itself. Oddly enough I had been suspecting that the malfunction had something to do with the change in air pressure, and seemed to be confirmed. I wonder if for some reason, maybe a design flaw, there are tiny air pockets in the phone that cause this problem. Anyway, won't be taking this phone travelling again, but I'm relieved it fixed itself... Hope this helps someone and the manufacturer corrects the flaws that would cause this, cause otherwise it's an awesome phone!
