Enthusiasts might argue that a “lite” or “modified” version of WhatsApp could have existed for the J20i. In fact, Sony Ericsson did produce a handful of “Facebook phones” around this time with integrated social media keys, and WhatsApp did release a Java ME client for a very brief period for legacy phones like the Nokia S40 series. However, this client was notoriously unreliable, often delaying messages by hours and consuming battery life at an alarming rate. Even if such a client were hypothetically ported to the J20i, the experience would have been disastrous. The phone’s 100 MB storage would have filled with message history instantly. The 64 MB RAM would have struggled to load contact lists. The resistive touchscreen (on the J20i’s rare touch-enabled variant) was imprecise. More importantly, by 2012, WhatsApp had already decided to discontinue support for Java ME, BlackBerry OS, and Symbian, recognizing that the future was in iOS and Android. Sony Ericsson itself was dissolving, with its mobile division being fully acquired by Sony in 2012. The J20i, a brilliant feature phone, was left adrift in a smartphone’s ocean.
