A:AnswerI had the same problem. I have a really cheap Android phone that won't let me use the official Google cardboard app (says unsupported.) However, I was able to find a third party viewer on the play store that did the job.
A:AnswerYes as long as they aren't thick or largely concave. You have to hold the viewer to your face and if your glasses are large, it keeps the viewer from blocking outside light breaking immersion not to mention pushing your lashes up against your lenses which is also uncomfortable and immersion breaking.
