Foldable phones: a brief history of failures and successes

For a long time, foldable smartphones were not available on the market. In fact, the development path of these phones has been difficult, due to the extremely disastrous release of the Samsung Galaxy phone. Since then, the other big companies have launched their own devices.

1- Samsung Galaxy Z Flip

In a report on Interstering Engineering, author Chris Young said that Samsung's new foldable phone "does not follow its design, but rather breaks it." Fortunately, the latest Samsung foldable smartphone appears to be more stable than the Samsung Galaxy Fold phone.

Although it's easy to notice the bending effect of the Samsung Galaxy Z Flip phone, its 6.7-inch screen easily folds into a pocket-sized device similar to the traditional clamshell style phone.

Perhaps the most important improvement compared to the Samsung Galaxy Fuld phone is the price of the Samsung Galaxy ZFlip phone, which amounts to $ 1,380, which is reasonable compared to the price of the Samsung Galaxy Fuld device, which is two thousand dollars.

2- Royal Pay Flex device

Royal's Flex Bay device was officially launched on October 31, 2018. Indeed, leading technology giant foldable company Royal has beaten big names like Samsung, thanks to its release of the Flex Bay device.

The smartphone uses flexible second-generation display screens for Royal, allowing it to curve freely from 0 to 180 degrees. The device's cameras include a 20-megapixel telephoto lens and a 16-megapixel wide-angle lens.

The Samsung Galaxy Fold phone was likely to be a prototype of the permanently foldable phone type, as the first Samsung foldable smartphone to be released. However, given the price of the device, which amounts to two thousand dollars, in addition to the emergence of major problems directly when using it, making it difficult for him to accept. On the other hand, the Samsung Galaxy Fold features a 7.3-inch Infinity Flex display, and a 4.6-inch screen when folded.

In addition, the phone contains six cameras and two batteries, each located on both sides of the fold, with a total capacity of 4,380 mAh. Moreover, the device has a screen resolution that depends on the expanded quadruple visual display system and a display ratio (4.2: 3) when used as an electronic board, HD resolution and a display ratio (12: 9) when folded to become the size of a smartphone.

4- Huawei Mate X

The Huawei Mate X phone was shown at the global mobile conference during the past year next to the room designated for the Samsung brand where it was displaying the Galaxy Fold, which is considered a smart phone that is foldable and impressive.

The phone, which is priced at $ 2,600, has a 6.6-inch front screen and a 6.38-inch back screen. In addition, the phone has an eightGB RAM and 512GB storage.

5- Motorola Razer

After promoting Motorola Razer as a phone to show the true potential of foldable smartphones, the reviews focused on the fact that its specifications, especially battery life, did not rise to the required level.

Based on the old, traditional clamshell Razer phone, the new Motorola Razer folds a 6.2-inch LED screen with a 2142 x 87 screen. Furthermore, the Motorola Razr, which costs $ 1,499, features a screen. The light-emitting diode allows users to answer messages without unlocking the phone.

6- The idea of ​​a smart watch from Oppo

While this design is just an idea outlined in the patent file, it could reveal an impressive new trend of foldable technology of a foldable smartwatch. The design idea, which is patented by OPPO and founded by Let's Go Digital, indicates that the company wants to compete against Samsung and Apple with its ambitious design. The idea of ​​a smart watch includes a rotatable screen so that the length of the screen can be extended without making it wider.
