For some reason I have a very unreasonable 34gb of data being used by my text messages (app). I have deleted countless threads and after 'updating' my phone I now have over 36gb of 'documents and data'. Before I delete everything off of my phone I have to ensure that everything is not deleted. I need to keep some of the text threads and be able to access them later for legal reasons. This has kept me from limiting how long the phone will keep the messages (1 week, 1 month, etc). I have deleted enough threads, photos, and videos to create space on the phone but my data and documents has increased. I don't want to restore my phone because I don't want all of the messages to appear on my phone again. Is there something I can do? I feel like this is going to be complex or very simple. Thanks in advance for any help! I will try to respond to questions asap.
