I just got a new android phone running 4.4.2 as an interim before I buy another phone. After factory reset, I tried to install Whatsapp. This was the first app that I tried to install and it failed after downloading saying that there was insufficient storage available. I tried doing it multiple times - to the same result.
Free internal memory - 1.1GB. Free phone storage memory - 1.3 GB. No other app apart from the inbuilt apps have been installed. Post this, I installed Facebook Messenger and it works just fine. I don't understand why Whatsapp isn't installing. Another messaging service called Hike Messenger also works fine. Please help!
Just tried installing "Advanced Task Manager" and "Advanced Task Killer" to the same result - insufficient storage memory.
