Hello,

So i received my quad cortex a week ago. Started playing with it a gew days ago and it sounds great. But i noticed one day when I tried to use it again, the button wouldn’t work. I never done any unplugging and it was able to turn off the night before and all the sudden i can’t turn it on. I unplugged the power supply that plugs into the wall the quad cortex is able to turn on. But when i try to turn the device off or to restart, the button isn’t working. Then when i try going to settings to restart, it doesn’t restart. I got this device new from Sweetwater and it came here fine. This statted to happen after the recent update. What do i do? I worry that when a new update comes, that my device wouldn’t be able to restart or update properly.

If a factory reset and restore from backup doesn’t resolve, it could be faulty. I would simply RMA with Sweetwater and have them send you another QC.

You might be aware of this already, but make sure you are pressing _and holding_ the power button to activate it. It will not activate with too short a touch.

Also, you can go to ‘Settings’ → ‘Device Options’ → ‘Power Button Sensitivity’ and change it to “High” and see if that helps.

Glad I found this. I may have eventually stumbled on it by menu diving but maybe not… so thanks.

On my 4th (yes, long story… keep selling them but hopefully keep this one)… I noticed the power button being more difficult to activate. Had to press harder than I remember from the other QCs I had.

Went in the menu option described by HonestOpinion above and adjusted it to High (was on Medium). Seems to make it much better. But now it’s maxed out.
