I'm sorry about the issue. What's the model of your cell phone?
Does this issue occur in a particular app? Or do you mean you cannot do anything on the phone right now?
Have you tried anything?
Please reply at the box below. Thank you.
Have you tried this: Press and hold the Power on/off button for about 20 seconds, then turn it back on and check. (If you have an iPhone, press and hold at the same time the two buttons Power and Home for about 15 seconds, then release, and check.)
- If that does not work, please answer my questions in my previous reply above, so I can help you further. When you are available, please reply at the box below to continue troubleshooting. Thank you.
