There's a whole flock of rumors surrounding the Samsung Galaxy S6 and they don't always agree. Earlier we heard that Samsung is likely to seal the battery with a non-removable glass cover, but now info from Poland comes that the company will do quite the opposite and do a small-scale version of Project Ara with the back panels.
Samsung is reportedly trying out different ideas with the replaceable backs that extend beyond the usual Qi charging or S View case.
The most intriguing (and most unlikely) panel enables additional lenses to be attached to the Galaxy S6 camera, which is rumored to be an optically-stabilized 20MP shooter. Such aftermarket lens are available for a number of phones, but we haven’t seen one straight from the manufacturer.
Next up is an E-ink back cover to transform the upcoming flagship into something like the YotaPhone 2. Barnes & Noble should love this idea, seeing how it borrows Samsung hardware for its Nook brand – E-ink screens are great for low-power always on screens and reading books.
Then there are covers that will enhance S-Health. One will measure your blood sugar and can upload the data to the cloud for your doctor's perusal. The Galaxy Note 4 can already measure pulse and blood oxygen level. Another case will integrate with fitness equipment and double as a bicycle computer.
All that sounds great though there aren’t any leaked photos of actual hardware yet, so take that as an unconfirmed rumor.
