After I update my Xperia zx I found some problems like my mobile become hot slow and sometimes frozen and not working only after minutes. 

I hope to find the solution

Hello @Nawaf1982

It's recommended after major updates that you perform a software repair using Xperia Companion. This will do a clean installation of the latest firmware and will also wipe your internal memory. Don't forget to backup using Xperia Companion, but preferably without adding apps or settings to the backup.

Follow the steps given in blue links, and keep us updated.
