Jio Phones do not run Android. They run KaiOS. Therefore, Android APK files will NOT install on a Jio Phone. Attempting to sideload an APK will fail or corrupt the device.
Introduction Jio Phones running KaiOS 2.0 (or later, like 2.5.1/2.5.4) are the most popular smart feature phones in India. A common search query is: "Jio Phone WhatsApp download KaiOS 2.0 install APK old version" .
A: Yes, but poorly. Older versions have buggy video calls. Newer versions are slightly better.
