There may be several reasons why the mobile phone can't edit the document suddenly:

(1) Document editing permission has been turned off. For example, some documents are set with editing permission when they are created. For example, read-only documents are only allowed to read, not to edit.

(2) Problems with the file itself, such as file damage, if it can be opened in other places, try to uninstall the reinstallation program.

(3) There is no software for editing documents on the mobile phone, just download the corresponding program and then reopen the document for editing. There are also some softwares that need to open members to edit documents with certain attributes. For example, if you want to edit a document with pdf properties in WPS, you need to open the member.
