Need help with Android (Droid 2) messaging [View all]

Hi there,
Hubby and I need to get new phones and we're looking at the Samsung Note 9 (hoping it doesn't blow up). That said, I have a question about our text messages.

First, both my husband and I don't understand a thing about this stuff and frankly, we just started texting about a year ago (yes!!). That said, there are texts I really want to keep.

We've been using Messenger+ and were told it doesn't back up and may not transfer to the new phone. As we won't get a new phone until this or next weekend, we have time to do some backing up.

So I have the following questions:
1. Is there an app that leaves the texts "in the cloud" or that automatically backs up? If so, what is that app?
2. Is there a way to transfer the texts we already have in Messenger+ and transfer it to the other app for backup?

Yes, I'll post this in the computer group but wanted to know all your opinions too. Please be very specific - neither one of us have any idea what is going on and the guys at Verizon aren't very helpful.

Thanks

Paula
