While the tablet sales marks declines every year, Amazon has found steady success with its kindle e-reader. Over the years, the company has made the e-reader more appealing by adding features such as backlit display, Wi-Fi connectivity and more.

Now, it plans to go further, by making the Kindle waterproof, according to a leak from MobileRead citing a Chinese retailer as the source.

“Only one pic leaked from a retailer in China, perhaps we can name it Paperwhite 4 or simplified Voyage. CPU still not upgraded, same flash storage as previous gen, same 300 ppi, Waterproofing. That's all, a very uninspired mid-market product. And kindle voyage & oasis would be suspended production, there will be 2 new models in 2018, 6 inch & 7 inch devices at high-end market,” the post on MobileRead’s forum suggested, along with a leaked image, which shows a Kindle sitting in a tray with identifying information blocked out. The image also shows that the device has been fitted with a glass display, which would help in waterproofing the device.

Amazon has kept it simple with Kindle — rather than transforming it into a tablet, it has simply pitched the kindle as an e-reader and backed wit with its vast collection e-books. Endowing the device with a waterproof functionality will make it even more portable for users, since they would not have to fear getting their device wet — it might work for passing time, when you are stuck in the traffic during the rain. Competing e-readers from Barnes and Noble and Kobo have been waterproof for years, so it's time that Amazon steps up to the plate.

Whether this could be the Kindle Paperwhite 4, is not yet known.
