There is a software update available for it at:
Sorry, I can't post the actual address, perhaps a moderator could correct it for me please?
This needs copying to an SD card then running the update app in the 'mgmt.' folder on the 'phone. The instructions (in a PDF inside the update zip file) tell you that all user data will be wiped as part of the update procedure, in my case this did not happen (phew!), but I can't say for certain you will not lose some information or some of your installed apps. I've no idea what this update contains, if anyone finds out please let me know.
I've come across one problem (before I did the update). If I've had my navigation app running (Co-Pilot Live) and I then close the nav-app and switch the 'phone to standby. When I try to start up the nav-app it won't find my location using GPS. At this point no other GPS enabled app will find my location either. As this happened on the hottest day of the year, I feared I'd cooked the 'phone in the car window! I tried re-booting the 'phone a few times, force closed Co-Pilot Live a few times, none of which worked. I got back to the hotel (we were trying to navigate from Birmingham centre in the evening rush hour when it first packed up!) and decided to switch the 'phone off completely to recharge it having visions of taking it back to the shop for a replacement. When I tried after the charge had completed, the GPS and Co-Pilot Live all worked correctly. After putting the 'phone to standby it again failed to locate me using GPS. I simply turned the 'phone off (long press on the power button then select 'Power Off'), waited for 30 seconds and powered the 'phone back on again. Again, it then worked correctly. Simple cure, once you know, but slightly inconvenient, though less inconvenient than returning a faulty 'phone.
It could be that this has been corrected in this software update, if not, I hope this helps someone.
With that minor niggle though, I think this is one of the best 'phones I've seen for a long time, I currently own an iPhone 5 and a Sony Xperia Z and think the P6 outshines both easily. I love the looks, the slim design and the default 'Brushed Aluminium' skin.
Huawei should be congratulated on this 'phone, it's a diamond.
