Won't work with large amounts of messages. I have almost 200,000 messages over the years and the problem I'm having is it only works in small batches or it will fail. The issue I'm having is that they only let you batch it up to two years. If they simply added an option for 3 years, 4 years, 5 years, etc, then it would probably work fine. I've been using Samsung since the s3, so why can't they repay my loyalty and assume I want messages back that far? I want txts from passed loved ones.
