The reason why the YotaPhone 2 differs from the rest of the crowd is not because of its E Ink display, but these two displays: one in the front and one on the back cover. And if you wanted a second display, but you do not want to buy a YotaPhone 2, how can you do? Well, now you can have the best of both worlds with popSlate and its case reserved to the iPhone.
The popSLATE hull has almost the same display found on the back of YotaPhone 2. Thus, you will find an E Ink display of 4 inch that reflects your main display and is always on. Once turned on, it connects to your phone via Bluetooth. You can use it to check your notifications and respond to all kinds of messages, especially if your iPhone is low on batteries. Furthermore, since it is still in use, you can display static images, such as boarding passes, train tickets or movie tickets. It is also very useful for all those who love to read e-books.
Through popSLATE application you can take pictures using the E Ink display as a viewfinder. You can also browse the pictures to view while you do not use the E Ink display, which should last a week on a single charge. In other words, if your phone no longer has battery, this image will persist until you choose to change it. This is a handy little tool that has a lot to offer. The E Ink display also means that it is easily visible, regardless of the lighting situation.
Fortunately, there is no need for additional charging cable owner, since the popSLATE hull charges via micro-USB port.
You can buy popSLATE case for your iPhone 5, 5S, and 6, but it will cost you $130. Unfortunately, at present there is no model for the iPhone 6 Plus, it could emerge soon.
