I have a Convoy 4 as my primary phone. I use the Verizon Messaging app on my tablet, Samsung Galaxy Tab, for most of my texting. The timestamps attached to most of my incoming messages, and some of my outgoing, started to vary approximately up to ten minutes in either direction of the actual times of sending and receipt, causing my conversations to be jumbled and out of order. I tried deleting and reinstalling the app, and that didn't help. Any help or advice would be appreciated.
