[G3 Q&A, Help & Troubleshooting] TyWillems19:
Hey guys,

This post is going to discuss an issue I had (and solved) with the motion sensor becoming stuck in the LG G3.

(My original thought was hardware failure)

So I know there aren't a whole ton of known issues out since the G3 is still new, but I just wanted to share one that I encountered that I thought could possibly be an issue that other people encounter, mainly because of how it happened, and my previous experience with the usage of smartphones in general.

So here is what happened:

I had my G3 from the release (Verizon) on the 17th of July. I had a hard case on it (black double enclosure case) and a tempered glass screen protector. I had chosed the case because I had used the exact same case on my previous HTC Thunderbolt and HTC Rezound and found that it was reliable and incredibly durable. Obviously, the reason for buying the case was to protect the phone from the instance that we all dread when we watch our beautiful smart phones fall in slow motion and hit the ground, hoping the no harm had come to your baby. Well, unfortunately it happened much sooner than I ever expected, and I saw my phone fall from about 3 feet up. Now, fortunately the fall wasn't very high at all, and in the past I had experienced my phones taking much stronger of a beating (rarely, but it happens nonetheless. I take excellent care of my electronics in general). I picked up the phone and examined it, and to no surprise everything seemed just fine so I thought nothing of it. Now after some time, I noticed that my screen wouldn't auto-rotate and I was a little confused at first. I thought it was hardware failure and I was a little concerned about the quality of the G3 at first, and I thought of the drop, but was just too far beyond the idea that such a small impact would completely break the motion sensing capabilities. After calling and troubleshooting at much as I could, I decided I was going to have to send my phone in the be repaired (at my F***ing expense...). Before going through the process, however, I had to give something one more try. I downloaded a ball-falling game to see what would happen with the motion sensing in the game. I opened it up and saw that instantly the ball would fall straight to the right of the screen. I looked, and thought back to how I saw my phone fall (very vivid in my mind, almost scaring trust me). It had hit the right side most definitely.

So here is the cool part. I thought, there is no way that the motion sensor became "stuck" because of a fall of that caliber. Or at all, I didn't really even think that it was possible for such a thing to happen lol. But I gave it a shot, and enclosed my phone in its case to make sure it would take as little damage as possible, but I went ahead and dropped the phone on its left side. I only dropped it from about a foot to be safe, but sure enough, I tried the game again and it worked perfectly. So that was my solution.

Basically to sum all this up, my motion sensor got stuck, and I had to jar the phone enough to knock it loose again (or at least that is how I understand it. The hardware might work in a different way, but this still worked).

I just wanted to post this story here just in case we find out that the G3 happens to have a tempermental motion sensing hardware device.

So if you have this issue, give it a try.
