Why can’t oppowatch2 see the SMS verification code?

The reasons why you cannot see the SMS verification code are: 1. A blacklist and information interception are set up. Smartphones are more convenient now, but some spam messages often harass users. Users have to set up blacklists, but sometimes they don't pay attention. Some settings in the settings options are not changed completely according to their own wishes, causing the information to be intercepted, so it is necessary to remove the blacklist. List interception.

2. Because the mobile phone storage is full, clear the memory or text message content, but this is unlikely.
