Verizon's early adopters of Samsung's latest Galaxy S5 flagship are having some trouble with their devices. Many are reporting their camera refuses to work after a few days. The error message just says "Warning: Camera failed".
There is no fix to be found. The users tried everything Verizon has suggested them to do - software and hardware factory resets, wiping caches from recovery, etc. Nothing works so far.
The unlucky owners are having their devices replaced, but there is no guarantee this won't happen again. There is even a Galaxy Note 3 on Verizon affected by the same problem already.
Hopefully this issue is resolved quickly by a firmware update. Meanwhile we advise Verizon's Galaxy S5 users to stay away from third-party camera apps such as Instagram, Shapchat, Facebook, etc. because some users are reporting the problem started after installing and using such an app.
