I have a 3rd generation Motorola Moto G. I recently updated it to Marshmallow. After doing this, at first I did not encounter any issues but soon afterwards, I started to experience many issues with Android, including:
- The pattern lock is absent
- I am unable to connect my phone to my computer
- The button to factory reset the device is greyed-out
- The drop-down notification panel is absent
How can I correct these issues?
