There has been some talk surrounding the 1308 firmware which arrived in Europe recently, targeting the Nokia Lumia 920 mostly, but do bear in mind that the Nokia Lumia 620 is also a part of that particular update, and it seems that a global rollout has already happened as the Internet has been abuzz with word from owners of the Lumia 620 that they have begun to receive this 1308 firmware update Over The Air (OTA).
How did we come to the conclusion that this is a global rollout? For starters, we have received word from Germany all the way to India and even Malaysia, where Lumia 620 owners have reported that they are receiving the firmware patch that is touted to improve overall performance. Among the other fixes on the Lumia 620 include better touch screen functions, corrections in multi-touch actions, improved voice quality with Bluetooth headsets, enhanced camera performance, and a more stable system among others.
