Now what is a foldable phone? The answer is pretty self-explanatory as you may think. Foldable phones are nothing other than phones that can be folded vertically or horizontally in half depending on the manufacturers’ model. These phones have been introduced in the market recently and have sparked the excitement in many “tech nerds” around the world. It functions just as a regular phone does, so you can navigate on the web, make phone calls, watch videos etc. basically the same functionalities of a normal phone. Now one may ask how it is possible to have a phone that folds in half. Well, engineers were able to birth this device through a hinge mechanism that allows the phone to close up like a book or reverse the process by opening up the device to 180 degrees or even more depending on the brand of the phone (e.g. surface duo). Foldable phones are like iPads or tablets that can fold in half but there are some exceptions like the ones engineered by Motorola which fold vertically and almost resemble a flip phone but with and touch screen body. Not only were the use of hinges necessary to build such device but also plastic touch screens were needed in order to fold or bend the screens which would not be possible with normal glass screens. Thanks to these two main components of  the device its folding mechanism can gracefully open and close the phone.
