So, a little bit of background. The worst part about this is that I'm pretty confident I know how to fix it, but I don't know how to go about doing the thing I need to do to fix it. Bear with me a moment.

So I have a stock Droid Turbo, I don't have any kind of ROMS or any non-play store stuff on it.

So what I did was I went into developer settings on the phone, the "Hidden Settings" and I started fiddling with stuff.

I either pressed on:

Simulate secondary displays or Force RTL layout direction

and the phone's GUI crashed hard. Now it's completely bonkers, and only endlessly loops the error that "Unfortunately, the System UI has stopped working."

Now my question is, is there a way to reset those options in the developer menu somehow, without doing a factory reset? I have a few apps that store local data that will get erased, and I'd rather not.

Additionally, the phone is still working in the background, I can hear text message notifications and it rings when I get a call, though I can't interact with it in any way. The Droid Turbo user interface (For gestures while the phone is locked) works too.

I tried clearing the cache, I tried letting it complexly run out of battery and doing it again. Hard resets. Nothing seems to work.

The worst part is that my PC Doesn't want to recognize it either, which is odd. While in the bootloader it got a connection to my PC as a linux USB Storage device, inside system recovery it made the noise like something is there, but it's not.

So any tips? any way to save my data before I have to factory reset this? I really can't lose that data, a few apps I have store user data locally.

    Is USB debugging enabled or a custom recovery installed? One of them is needed to revert those settings. Which Android version is it?

  • @Firelord Yes, I have USB debugging activated on my phone. As for custom recovery, I don't think so. My android version is whatever the newest sweets name is. I wish I could tell you but obviously I can't go into the phone to look right now. Oct 21, 2015 at 23:35
  • You mean Android Marshmallow?

  • Yeah that sounds right. I'm pretty sure it has it. Oct 21, 2015 at 23:42
  • To reset "Simulate secondary displays", use PC and adb to execute the command adb shell put global overlay_display_devices ''. Note that '' means blank here (there is no gap between apostrophes). You can replace it with ' '.

If your phone is encrypted, the only thing I can think of to get your data is to install a custom recovery, a custom ROM which uses a custom system UI and start the phone. Your data should be there. If it's not possible, you will have to turn off the phone, press and hold power on and volume down and factory reset. This last part is not recommended since you may loose your data.


Why not just install a recovery on an sd card and then install it through the stock recovery mode and reboot into it. The only thing i'm an expert on, is not being an expert, so I might be way off in regards to your Droid. I had to do it on my s5 galaxy and it worked on that.

  • Seems fairly legit, to be honest.
