A few weeks ago, Nokia released a new firmware update for Lumia 920. The company said that the update brings performance improvements, improved display brightness adjustment and updated proximity sensor parameters. Unfortunately, the company was not aware of the potential update problem which affected more than 70% of users.
According to reports, users were experiencing connectivity issues on 3G as well as on LTE with their phones. The company confirmed the issue and said that they are working on a fix. In the meantime, the 1308 update has been halted.
