Apple has released iOS 7.1.2. The update improves iBeacon connectivity and stability, other bug fixes and security updates including a data transfer bug fix, and a fixed issue with data protection class of Mail attachments.
iOS 7.1.2 is available over-the-air or through iTunes. Before you update, it is a good idea to charge you device to at least 50% and have it plugged in before carrying out update.
I must admit I haven’t updated my iPad yet. I finally have sorted the battery life and don’t want to do anything to jeopardise this. So far I have had 10 hours usage and the battery is at 46%.
