iOS update

Hey everyone, I have an iPhone 6 plus, and I recently updated it to 10.0.2 and I'm having many troubleshooting with it ever since. Here are the following symptoms:
Whenever I text, the marker is on the left instead of the right (-I'm writing in Hebrew). This includes Messages, E-Mail, and Whatsapp.

Also, in the mail app, sometimes in the conversation the whole order gets scrambled.
