Are you hand holding your phone or do you have a mount that will accommodate the XWs?
Hand held.. The only one that really gives me issues when taking pics is the 5 XW. I have to hold the phone far away enough to avoid blackouts but close enough to see the full field. The adjustable eye guard helps a little, but steady hands and a bunch of snapshots are keys to success. The 7 & 10 are much easier to snap photos with.
