Unable to open Htcm8 information. Display application is not installed.

According to your description, I suggest you try the following methods:

1. It is recommended to go to Settings-Application Manager (Application-Manage Applications)-All-Find Software-Clear Data and try again, or reinstall.

2. Check whether software programs such as mobile phone security guards are installed in the mobile phone. If there is an attempt to uninstall, please check whether the installed third-party software is incompatible or caused by software restrictions.

3. Check whether the phone has enough memory.

4. Check whether the version of the software installation package is the latest.

5. See if other software can be installed on the mobile phone.

If you can't install the software on your mobile phone, I suggest you send it to your nearest service center for maintenance. I hope I can help you!
