INCORRECT PICTURE IN NEW MMS
For those using Messages App and are also in the habit of deleting messages after being read may encounter some difficulties with newer MMS messages displaying the incorrect picture. As a matter of fact, a previously deleted picture shows in place of the new picture message.
Previously deleted MMS picture shows up in newest incoming MMS message instead of the intended accompanying image.
Situation as it unfolds
Short term solution for the time being: CLEAR CACHE
GENERAL → APPS & NOTIFICATIONS → APP INFO → Messages → Storage → Clear cache
NOTE: Only the first picture is wrong. Subsequent pictures from the new incoming messages will be correct.
Permanent solution: Google has developed and provides an app update through Google Play Store since February 2019 (version 4.0.054). So long as the App software version is 4.0.054 or greater, please update to resolve this issue.
