Scientists at the Indian Institute for Science Education and Research (IISER) in Kolkata have created an innovative screen protector for smartphones.
It is hard and transparent glass, cracks on which can heal on its own. Glass is created using a piezoelectric organic material that is capable of converting mechanical energy into electrical energy and vice versa. The result is needle-shaped crystals 2 mm long and 0.2 mm wide.
The unique molecular basis of the material allows individual particles or crystals to “seal” cracks. Scientists themselves are confident that their development is ideal for smartphones. At the same time, it is stated that the new glass is 10 times harder than solutions already on the market. Large cracks are unlikely to be removed, but small ones that arise during daily use, such glass is quite capable of eliminating.
It remains to add that in recent years we have repeatedly heard about such innovative glass, which can be independently restored. But the matter will not reach commercial application.
Unfortunately, the staff of the Indian Institute of Science Education and Research did not give a time frame when smartphone manufacturers can start using their development.
Snapdragon 8 Plus Gen 1, Enhanced Hinges, 6.7″ Dynamic AMOLED Folding Screen, 1.9″ Secondary Screen, 3700mAh. Samsung Galaxy Z Flip 3 clamshell smartphone unveiled
Samsung smartphones with flexible screens traditionally come out together, so today, along with the Galaxy Z Fold 4, the Galaxy Z Flip 4 also debuted. Here, too, there were no revolutions, and, unlike the older brother, the camera has not changed at all.
Therefore, one of the main innovations is hidden inside – the Galaxy Z Flip 4 is built on the Qualcomm Snapdragon 8 Plus Gen 1 single-chip platform. The amount of RAM is 8 GB, the amount of built-in flash memory is 128, 256 or 512 GB. The cost of the basic version in Europe is 1100 euros. Starting today, pre-orders are being accepted, retail sales will start on August 26.
The second improvement is related to the power subsystem: the battery capacity has increased from 3300 to 3700 mAh, and the charging power has increased from 15 to 25 watts. And this is a highly anticipated update.
The main camera of the smartphone uses 12-megapixel sensors. The main one is with a wide-angle lens with F / 1.8 aperture and optical stabilization system, the additional one is with an ultra-wide-angle lens. Exactly the same scheme is used in the Galaxy Z Flip 3.
The main folding screen is Dynamic AMOLED with a diagonal of 6.7 inches, Full HD + resolution, a frame rate of 120 Hz and an aspect ratio of 22: 9. The embedded front camera is 10-megapixel.
The outer screen has not changed in any way: a small 1.9-inch AMOLED panel with a resolution of 512 x 260 pixels. But Samsung has expanded its functionality. So, for example, messages can be answered directly from the outdoor screen (using emoji), the theme of the outdoor display is synchronized with the main theme, and additional widgets have also appeared. For example, you can call up to three favorite contacts from the external display – without opening your smartphone.
Other features of the smartphone include an aluminum frame, a side-mounted fingerprint scanner, stereo speakers, and IPX8 water resistance. Dimensions Samsung Galaxy Z Flip 4 folded – 84.9 x 71.9 x 17.1 mm, unfolded – 165.2 x 71.9 x 6.9 mm. Weight – 187 grams. The operating system is Android 12 with OneUI 4.1 interface.
7.6-inch QHD+ AMOLED screen, Snapdragon 8 Plus Gen 1, 50MP camera, IP68, 4400mAh for $1800. The flagship Samsung Galaxy Z Fold 4 is presented
Samsung today officially introduced the flagship smartphone Galaxy Z Fold 4. The novelty does not bring revolutionary changes – the developers just tried to make one of the most popular smartphones in the world with a flexible screen even better. Whether it worked out – time will tell.
As befits a flagship, the Galaxy Z Fold 4 is built on the Snapdragon 8 Plus Gen 1 single-chip platform. The amount of RAM is only 12 GB, but there are three options for flash memory. Standard – 256 and 512 GB, and on the official website in some regions it will be possible to buy a version with 1 TB of flash memory.
The Samsung Galaxy Z Fold 3 had a triple 12-megapixel camera, the Galaxy Z Fold 4 has only one 12-megapixel sensor – it is used in the module with an ultra wide-angle lens. The main module has a 50-megapixel sensor, a wide-angle lens and an optical image stabilization system. There is also a module that provides 3x optical zoom (or 30x the so-called “Space Zoom”) – it uses a 10-megapixel sensor.
The front camera of the outer screen is with a 10-megapixel sensor, and inside there is a 4-megapixel sub-screen front camera.
The internal screen of the Dynamic AMOLED 2X when unfolded has a diagonal of 7.6 inches, an aspect ratio of 6: 5, and a resolution of QHD+. The frame rate reaches 120 Hz, the brightness is 1000 cd/sq.m. It is protected by tempered glass Gorilla Glass Victus +. Outdoor AMOLED screen – with a diagonal of 6.2 inches, a resolution of 2316 x 904 pixels and a frame rate of 120 Hz.
The smartphone is well protected from water (IPX8 rating says that it can withstand a half-hour submersion to a depth of 1.5 m) and has a fairly solid construction (tested for 200,000 unfolding and folding cycles).
The battery capacity has not changed – all the same 4400 mAh. And the maximum power of wired charging also remained the same – 25 W, but the efficiency has clearly increased, as the smartphone charges faster: by 50% in half an hour (Galaxy Z Fold 3 was charged by 33% in the same time). Both 15W wireless charging and 4.5W reverse wireless charging are supported.
Galaxy Z Fold 4 large screen can display two windows (next to each other) or three windows. At the bottom there is a panel, similar to the taskbar in Windows – the company tried to make the interface as convenient as when working with laptops. From the impromptu taskbar, you can call up your favorite applications or, for example, those that have been recently used. Of course, the smartphone works with a proprietary digital pen S Pen.
The Galaxy Z Fold 4 configuration also includes stereo speakers, a side-mounted fingerprint scanner, and a USB-C 3.2 port. The frame is aluminum. Dimensions unfolded – 155.1 x 130.1 x 6.3 mm, folded – 155.1 x 67.1 x 15.8 mm. Weight – 263 grams. The operating system is Android 12 with One UI 4.1 interface.
Prices are announced, and they are considerable. For a basic Galaxy Z Fold 4 with 256 GB of flash memory, they ask for $ 1,800 in the US, and 1,800 euros in Europe. The 512GB version costs €1,920 in Europe, while the 1TB version costs €2,160. Pre-orders are already being accepted, retail sales will start on August 25.
