Why does the oppo mobile phone application show that the installation package is damaged and cannot be installed?

Try downloading or updating the software in the software store. If the software tips downloaded from the software store cannot be installed, you can refer to the following methods:

1, if the mobile phone is not powered on from unknown sources, just switch on the phone settings-general/other settings-security and privacy-unknown sources/allow the installation of applications from unknown sources;

2. The memory of the mobile phone is full. It is recommended to clean up the mobile phone garbage and leave enough space in the memory.

3. The preferred installation location is wrong. Go to Settings-Storage-Preferred Installation Location-Select by System, and then download and install again;

4. The version of the installed software is lower than the existing version, or it is caused by software compatibility problems. Please change to another version or download and install other software again;

5. The mobile phone has obtained permissions such as ROOT to change the stability of the mobile phone system. It is recommended to go to the customer service center to brush the machine to remove the ROOT status of the mobile phone.

If the problem still exists, please bring the purchase invoice, warranty card and machine to the OPPO customer service center for testing, and a professional engineer will solve it for you.
