hello everyone,
I just needed some help with my Acer Iconia one 7 B1-770. I hit the display brightness/darkness at its minimum and found out I can't see nothing at all. I thought there might be issues with low battery but when I pressed the volume, I could hear any sound. Unfortunately, I cannot use my tablet anymore.
Does anyone could help me how to fix this issue??please.
Thanks & God bless.
Esta é uma boa pergunta?

I had a friend bring this issue to me…
turns out the brightness was just down to zero..
so pull down from the top of the tablet twice.
then about 1 and a half centimeters down just try to use your finger and catch the brightness slider and slide it to the right again and voila… working again.

Hello, have you tried a factory reset? Follow these steps:
1. Power off the tablet.
2. Press and hold the Volume up button, which is located closest to the touch screen lock switch.
3. While holding the Volume up button, press and hold the Power button for 3 seconds then release it. Continue holding the Volume up button.
4. Once the tablet screen turns on, stop holding the buttons.
5. On the Android system recovery screen, select wipe data/factory reset. Use the Volume up and Volume down keys to navigate through the menus and use the Power button to select the desired option.
6. When prompted to "Confirm wipe of all user data", select Yes -- delete all user data.
7. Select reboot system now.
