I've got a weird problem on my brand new Nexus 6. To my surprise, my text messages integrated properly (using Titanium Backup, from Droid RAZR HD on Cyanogen 4.3.1). Everything is there in the stock messenger, in order, showing the right "most recent activity". But then I restored Handcent. And while _most_, but not all, of the contacts are in order, the most recent activity is wrong. Second, now when I edit contacts (such as for my workplace), it places a blank message in Hancent (but not stock). Thirdly, I can't delete any messages from Handcent. And finally, it's not just Handcent that's doing this. It's all 3rd party messengers I've downloaded. Lollipop 5.1. Rooted. Not sure what other information would be needed, but I'm happy to provide.
