I realized that I did not have any limit on the number of text messages that have been stored on my Samsung S6 and the app shows 510MB used of which 353MB is data. I am individually reviewing the strings of messages and have deleted several thousand across all my contacts including hundreds of photos/ attachments yet the amount of data has not been reduced. If anything, it appears to have gone up a few MB since I began the exercise.
IS there anything I need to do besides deleting these individual messages to reduce the storage?
I am at release 6.7.7
