I have a Nexus 7 and an Asus TF300. They both are running Android 4.1.1.

Yet, the N7 will not make WiFi ad-hoc connections with my phone running Joikuspot as a Wifi Hotspot.

The Transformer (unrooted) has no trouble whatsoever, and neither does my iPad or any other tablet I've tried.

Why doesn't the N7 work in this regard, after all they are both running the same version of Android and they are made by the same company.

Is it something related to the firmware that stops the N7 from using ad-hoc wireless networking?

I've just experienced this problem on my day old Nexus which is why I went looking for a forum such as this and hence my first post.

I really thought that I had somehow bricked the device after playing around with a widget that allowed the turning off of things like wifi, BT, and a button that seemed to allow cycling through various brightness states (full, auto, etc)

When I touched that brightness button one last time the whole display went black.

The power button seemed to have no effect. Even holding it down long enough to get the Google logo didn't work. A large X in a box would appear for several seconds and then back to blackness.

I was just about to try some of the solutions in these posts when I suddenly saw the very faintest of images on the screen. After a lot of playing around in dark and light rooms I could see that my home page was indeed there. That brightness button appeared to have had a "turn off all backlight/brightness" setting.

It took a long time but by randomly tapping in the area of the screen where I knew the widget was I was able to hit the brightness button and I was back in business. I've now got rid of the widget.

There is probably a quicker way to restore the brightness but my knowledge of Android and Nexus extends back only one day.

I just wonder how many people might have returned their Nexus as dead after accidentally finding the same "feature"
