Well, I survived it, and as ever I'm immediately underwhelmed. Accepted, it may just be that I'm an old git, and can't find new stuff into the bargain, but here are my initial observations.
1) Got Data Sense. Okay, that's nice.
2) Got Lumia colour profile. Doubt I'll ever use it.
3) Mobile network now says 3G and 4G instead of 2G and 3G. Fair enough.
4) Battery saver has undergone a software downgrade. Used to tell me time since last charge and time remaining. I found that useful, even if time remaining was usually a laugh.
5) Got double tap to wake. Tells me turning this on uses more power. The last thing my phone needs is something that uses more power.
6) Got glance screen. Don't know what this is so I'll have to have a play.
7) Got call+SMS filter. Might be vaguely useful if I could figure out how to block a number. Anyone enlighten me?
8) FM radio? Where might I find the new feature that I was really looking forward to? Either it's well hidden, I'm dim, or both. Anyone enlighten me?
9) Still can't give custom labels to contacts' details. I know this wasn't expected, but we still can't do this simple thing? Come on.
10) Standard ring tones and alert tones look the same old rubbish. Again, nothing was expected here, but a bit of innovation?
I know I sound like a moaning old git, but like Portico I'm pretty much left cold. Okay, Amber is better than Portico, and any improvement should be welcomed and I do welcome it, although improvement is always subjective. Just waiting to be shot down in flames now.
