Yeah,I agree.If this is indeed the case,I'd just return it within your carriers time frame (typically 14 days from purchase) for a refund,or another model altogether if this is really that bad in sunlight.
I've owned several phones from most of the well-known mfgs & all of them lose a bit of visibility in sunlight.
If memory serves me right,the best phone that I've owned for outdoor use is the Motorola Photon.
This subject has the potential to turn into another "Battery Life" discussion.............
