Is there a way to back it up that can allow me to restore it easily? Like an app or something which will restore everything- like whatsapp messages etc..
I assume that your phone is rooted.
Search for titanium backup in play store and backup all your apps. I'm not entirely sure if it will backup your messages and contacts, so I suggest that you use an app called super backup as well.
Try to reinstall your firmware and see if your phone is faster. And make sure you only backups application and not system settings, since those settings might make your phone slow again. I will also suggest that you transfer the backup folder to your computer, just to be on the safe side. Re-download the apps and restore your files after the installation
I'm not sure If this post covered all your questions, so feel free to ask me any questions that you might have
