Why can't I reply or read my Nokia C7-00 SMS after sending it?

Did you upgrade to Anna system? I encountered this problem after upgrading my N8. I sent a short message and got stuck. Looking for the reason for a long time, I found it was the input method. At that time, I used the sogou input method, but when I got in, I couldn't get out. Later, I solved it with system input method and Baidu input method. QQ I haven't found this problem yet. You can close QQ and try again. Try it, just for reference, don't scold me if you can't, hehe.
