iPhone 4S upgrade to iOS 9.3.1 forget text messages

I have an iPhone 4 (32 GB) s. It's on iOS 6. I have upgraded to iOS 9.3.1. He deleted all of the previous text / imessages (that's fine).

But now I get the text / late iMessages. It is also lose (forget / deletion) messages since I had since the upgrade. Sometimes (most of the time), it erases all my messages and I do not fit them. I also suspect that I don't get some messages to all (text and iMessage).

I tried:

-Turning iMessage market

-reboot the appliance

-Reset network settings

This is a 180 full of what I come to expect from Apple.

I googled for the solution for this, none were found.

Try this:

Backup on iTunes

Restore as a new

See if the problem resolves

If the answer is Yes - restore backup
