Why i'm starting to hate loving my Nokia Lumia 920

There seems to be an issue with the proximity sensor where on calls the screen will go dark straight away as if you have the phone pressed to your ear. The only way to get the screen on for a fraction of a second is to the hit power button and then try and tap the hang up button before the screen goes off. As you can imagine, using IVR menu systems is a pain and i've left countless voice-mails.

Google revealed that I wasn't alone in this issue and it looks like when dust gets in the ear piece it can easily travel across to the front facing camera and the proximity sensor... What a design flaw!!

So so the phone is less than 28 days old so I give Phones4u a ring (Mines a offline Lumia 920 red) and they ask me the usual questions:

Have you got a screen protector on?
Have you tried resetting the phone?
Are there any other issues?

I hadn't done a factory reset but agreed to do this. I had to call back after 40 minutes as the spinning cogs logo hadn't progressed and they advised me it was bricked. I'd already googled and wp central suggested its bricked, although there was an unofficial workaround I didn't want to void the warranty if the device had any flash counters.

I got a replacement code but nearly every damn Phones4u in the SW London area didn't seem to have stock of this particular model so I now have to wait to send my device back and then they will send me a new one. Awful customer service on Phones4u's part. Pretty poor QA testing on Nokia's part... I was seriously considering jacking it in for the HTC or Samsung WP8 devices... We'll see how the replacement goes...
