The cutout for the home button is oval in shape, and this has fueled plenty of speculation that it is most probably going to be the very same spot where the fingerprint sensor will be located. OnePlus has already teased us that the OnePlus 2 will come with a fingerprint scanner, and OnePlus co-founder Carl Pei did make a passing mention before that he has no love for fingerprint scanners that are mounted on the back.
It also does seem as though the OnePlus 2 will have a build of 148.6mm x 71.7mm, which would make it smaller than the OnePlus One. However, as with all leaks and rumors, we should always wait for something official to surface before making any concrete conclusions.
