I love Nokia's product range, stylish, technologically advanced and beautiful to look at. I have used Nokia 625 with Windows 8 mobile phones and love the way they function and look. Reliability is never an issue and the menus are a breeze to learn.
I have bought many Nokia phones over the years and their symbian phones were simply the best I have owned till date. Too bad they seem to have lost so much over the years and are now owned by Microsoft. For me, its been a good ride and truly the end of an era as far as I can tell.
The Nokia Lumia 520 is a Windows phone. and as such it seems to perform so far (a week) pretty much as advertised and as expected. What they don't advertise, and what I didn't expect, was the huge cost incurred by the phone, even when not in use. My Nokia has an Orange (EE) PAYG SIM card. What appears to happen is that the phone automatically performs frequent software and/or data updates whenever it's switched on (and what's the use of it if you can't leave it switched on?) These updates rack up your data costs at an alarming rate if you're on PAYG - mine amounted to about £60 in 5 days. It is by no means easy to discover what features listed in the Settings menu are causing this, (the Manual does not mention this problem at all, unsurprisingly) but by disabling most of them I seem so far to have stopped the runaway consumption of credit. I now have a phone suitable for voice and text communication, but can't afford to use it for anything else. It may be that if I found a contract with unlimited data allowance this would not be a problem, but this too seems quite an expensive way of using a phone, given my limited usage..
My Nokia N8 has been plagued with problems since day one. Whilst the hardware seems solid, the software/firmware has only got worse wit each successive update, leading me to believe Nokia deliberately degrade their phones in the hope we as consumers will blindly upgrade to their latest handsets. Their customer service was appalling and they never resolved the issues.
I strongly advise AGAINST any dealings with Nokia in any capacity.
