With the development of production technologies of smartphones, that is, with the advancement of SMD technology in electronic evenings and the proliferation of functions in operating systems, a new smartphone model emerges.

In fact, one of the most important reasons for the rapid development of phone technologies is user experience. There are two types of feedback that people form as a result of their experience of using the phone. The first is the features added to the phones as a result of a new need. The second is the negative situations that occur as a result of user experiences on phones. In other words, development occurs not only through electronic and software technologies, but as a result of user experiences.

A lot of work can be done with a smartphone. It can be used for entertainment purposes, it can also be used for many different jobs. And a smartphone must also adapt to the environment people are in. In terms of physical properties, ergonomic design, robustness. Today, especially with the widespread use of the internet and social media, the concepts of image, sound and storage have also become important concepts.

The stylish design of the phone is also an important feature, which appeals to the vast majority of people who use smartphones. It is not an easy task to appeal to all people's tastes, but field research, ie customer-user feedback-reviews, of mobile phone companies can determine the average eye-pleasing level of the customer base. It is important not only to specify the physical format properties, but also to specify the color options.

Especially in the last one or two years, Samsung, OPPO, Vivo, Motorola and even Huawei brands have launched their foldable products. One of these products is Samsung's Galaxy Z Flip4. The first thing to notice on the Galaxy Z Flip4 phone is of course its foldable feature.

Foldable phones actually existed in earlier times. We remember the old foldable models of Ericson and Blackberry phones with a simple operating system. When chip technologies went down to nano dimensions, the development of multi-core processors, the development of high-capacity memory chips, the development of display technologies made phones multifunctional and much more functional.

In fact, the development of chip technology is not the first thing users look at. The difference in physical usage features is the first thing that attracts phone users. For example, the wide-angle foldability of the Galaxy Z Flip4 phone, the fact that it does not require the use of a tripod when shooting videos and photos is the first thing that attracts users. This is the first factor that pushes customers who are already Samsung customers and use previous models to buy this phone.
One of the most important factors in choosing a phone is battery usage time and overall battery life. How much power the circuit elements used in the electronic circuit design of the phone draw affects the battery life. Especially how the screen technology is designed is an important issue. OLED and AMOLED screen designs provide a significant advantage in power consumption.

Of course, the other physical and electronic features of the Samsung Galaxy Z Flip4 phone are also worth considering. There are 12 MP wide-angle camera, 12 MP Ultra wide-angle camera, 10MP selfie camera. The Nightography feature of the rear camera is noteworthy. The Nightography feature ensures that night shots are clearer than other models. Thanks to the 1.9-inch cover screen, applications can be accessed without opening the folded phone. This is a huge savings from a power consumption perspective.

Galaxy Z Flip4 model has IPX8 protection standard. It provides water protection up to 30 minutes at a depth of 1.5 meters.

Some other features of the phone are as follows:
3700 mAh battery, processor/CPU QUALCOMM SM8475-OCTA-CORE 3.18 GHZ 2.7 GHZ 2 GHZ, screen size 6.7 inches, screen resolution 2640 X 1080 (FHD+) pixels, internal memory 128 GB, RAM 8 GB, Operating system Android 12.

Where are phones going in terms of physical-foldable?

The production and spread of flexible displays may begin in the near future. With the screens being foldable and bendable like a sheet of paper, the concept of the phone may also change. Even if the screen technologies are very advanced, we may have to wait for the electronics of the phones to be flexible and bendable.

We shouldn't ignore holographic screens either. The production and widespread use of a holographic phone-computer in our palm is not far away. The holographic smartphone actually becomes the most useful phone for humanity. Because we will use all the materials necessary for the production of such a phone at the minimum level, and we will do the least harm to nature.
