Hello everyone. I used apk editor because I wanted to move whatsapp to the sd memory. I backed up the data. I uninstalled and put the modified version in the apk editor temp file. Now I open whatsapp and when I install it, I enter the phone number and I get this message: there is a problem with your whatsapp version.download the latest version from the Google play store. How can I solve it in a simply way? thanks. can you help me? I have a galaxy s4 version
