It started after the new 5iu update, just updated last night. I tried reset phone settings cleared cache and data, also cleared partition cache still same issue, I haven't tried a full reset yet.
Blimey mate, looks like you've got yourself there a software problem. Since it at least attains a 1x zoom then I don't think it's hardware related so long as there wasn't any form of physical damage, but you should get an expert diagnosis from a Samsung repair store or an authorized third party regarding that or at least try it yourself by going to the diagnostic section of the Members app.
Yes! I was going to ask if you've recently had a new OS software installed. Then that is the problem, don't do a factory reset yet as there is no guarantee it will solve the problem. Do contact Samsung ASAP and let them know, they can escalate the issue to the appropriate department so they can issue out an update/patch or lead you on how to go about it. If they're not singing the song you want to hear mate then do a backup and reset the phone to see if that works.
I am ensured you that it's a hardware problem you should check first their is any updates notification if yes then do update after the update if your problem still there then do contact with their support http://www.samsung.com/us/support/service
