How to transfer and install an older version of Whatsapp from one phone onto a another phone? My whatsapp auto-updated to the new version yesterday which has the blue ticks. Since I am not a big fan of this version, I was wondering if I can install an older version of this app on my S4. One of my old phones(S3) has the previous version of whatsapp. Is there a way I can transfer this version to my S4?

Thanks for your help.
Two ways->

1) If you are rooted-> Go to data/app and there you can find whatsapp apk file. Just transfer it normally using bluetooth or whatever.

2) If you are unrooted-> Create a new folder Apps inside your internal sdcard .Download terminal emulator. Open it and enter the command cp /data/app/*.apk /sdcard/Apps. This will transfer all the installed packages in APK form including whatsapp apk. It may take sometime depending on number of apps you have installed. You could also just minimize terminal and wait.

3) As others suggested, you can also download from third party site on web.

A note though, as far as I can remember, whatsapp will persuade you to install new versions and wont let you use older versions. But again, I could be wrong so feel free to give it a try.

Hope this helps :)
