The back of your headphone is useless . There . I said it . surely , the cameras are back there , but what about all of that blank real estate monopolizing 90 % of the surface area ? Honestly , it needs to begin carry its exercising weight around here . A in full officiate screen is n’t the answer , however . That ’s a plenty more electric battery drain , a dense design and a much eminent Mary Leontyne Price tag — for what , exactly ?

The whimsy of a junior-grade east - ink screen is not a raw one . YotaPhonedid that years ago . Ultimately , however , the company declare bankruptcy in 2019 , four age after releasing its second twist . By then , foldable twist had already been on the market place for a couplet of years , depict the innovation as little more than a passing gaud .

Having played around with it a bit , it behoove me to mention that this is the prototypiest of prototypes . Not only are we not talking about an factual product here , but also the tech Infinix was showcasing necessitate the dummy social unit to be hooked up to an external battery coterie .

Like E Ink , however , the back panel does have the advantage of holding a inactive image even when the barrage fire is n’t putting in the work .

It remains to be see whether this gets licensed by a third company or plainly exhibit up on an Infinix gadget . My guess is the Hong Kong party is hoping for the latter , as it ’s hard to guess too many the great unwashed purchasing a smartphone based on this technology alone . For one matter , it does n’t really do much .

For another , as mentioned above , it ’s probably going to be covered in some shape or form 99 % of the sentence , save for those rare occasions when you want to show a friend the weird thing your phone does .
