What would Samsung do next for their mobile phone display?

After folding mobile phones, people wonder what will be the next innovations that Samsung will create in their display device.

With the foldable display, Samsung has been creating a different standard for the mobile device. However, according to what it planned, there will still be more extravagant things to be the next features for the display. Recently, there has been a patent published to prove the point. Samsung is too ambiguous to keep itself in a safe place with no more insane innovation.

The patent was mentioned in a post on the World Intellectual Property Organization’s Website, with the idea of a continuous display. According to that, there will be a seamless single screen made by jointed 3 separate displays for the device. Thanks to the invention, the phone can be wrapped up by the screen and enable users to see from sides and front, and the top edge.

You can imagine it is like another foldable model for Samsung phones. However, it is different from the Galaxy Fold. When the Galaxy Fold hides its screens inside , this new version shows the screen on the outside. This makes the device similar somehow to the Huawei Mate X, but the concept for the new Samsung innovation display is still processed and really potential.

The idea has just been recently approved and posted as a patent, although the original was planned back in 2016. It took more than three years to form the idea and make steps for an innovation. With more and more ideas for the world of foldable displays in Samsung industry, it is likely to be the approach to the new generation of mobile phone smart phones, with foldable phone standard.

Reviews on Samsung Galaxy Fold claimed its inner display malfunction

This first foldable Samsung Galaxy has been available for preorder and collected many reviews. However, there are complaints about the display malfunction, when it breaks when they use. The feedbacks of the early reviewers confused the production process and made it stagnant.

Samsung Electronics Co Ltd received reports which claimed display malfunctions in the foldable smartphone sample that is going to be officially unleashed.

However, the display can be folded like a book with the full size of a small tablet.

This smartphone was highly anticipated to attract users and create a new trend among hi-tech addicts. Yet, after one or two days releasing for some testers, malfunction was said to appear on its display. As the reply, Samsung promised to inspect the problem and find out the cause.

3 years ago, Galaxy Note 7 also coped with malfunction after launched. Its battery and design flaws lead to explosion. Samsung had to recall all their products and cancel their sales at that time. As the consequences, Samsung lost all of their profits in the third quarter of 2016.

With the new foldable smartphone, there is not only the malfunction in the display like being said before, but also the design is doubted to be less durable than Huawei’s products. Analysts say that in-folding adds more pressure on the screen, so it is more difficult to make than out-folding. Some reproters even say that their screen broke and unusable after being folded. Samsung needs to find out solutions soon if they do not want to cope with huge loss.

Apple implicitly criticizes Facebook and Google for privacy problem

Apple implicitly criticizes Facebook and Google for privacy problem
Not mentioning Facebook and Google directly, but Apple borrowed the privacy theme to attack opponents throughout their 25/3 event.

At the event that took place last night on March 25 in Cupertino, California (USA), Apple in turn introduced a series of services including Apple TV Plus TV, News + online newspaper, Arcade game or physical credit card. Apple Card. In the presentation on the stage, the American company constantly emphasized privacy and reiterated previous statements regarding the unauthorized sharing of user data.

For example, when announcing News + paid news service, Roger Rosner, vice president of application, said Apple would not know what users had read and would not allow advertisers to track them.

Like Apple Card, Apple thinks that they won’t know what users buy, where to use the card, because the data is encrypted and the company doesn’t collect it. Besides, partner Goldman Sachs also pledged to “never share or sell your data to third parties for marketing or advertising”. Arcade gaming service will not collect any information unless consent is given.

Although it does not give any comparisons to any brand, Apple is said to be its biggest target: Facebook and Google. The two tech giants have recently been strongly condemned by the business model regarding the collection of users’ personal information, then used for marketing purposes. Even, both were penalized in some countries for violating user privacy.

This is not the first time Apple has emphasized its commitment to privacy, and used it to attack opponents. At CES 2019, which took place in January in Las Vegas (USA), Google promoted Google Assistant aggressively by pasting the words “Hey Google” (the phrase used to activate virtual assistants) on buildings and cars . Apple then displayed a single ad next to the area opposite the CES exhibition, saying: “What happens on your iPhone will still be on your iPhone.”

iPhone has been left behind at least 2 years by Samung Galaxy Fold

iPhone has been left behind at least 2 years by Samung Galaxy Fold

Analysts from Goldman Sachs, Rod Hall and his team made a bold statement that Apple products and iPhones were left at least two years away from Samung Galaxy Fold. “Galaxy Fold is impossible for Apple. We can see it as a challenge for Apple in the context that the company has not yet approached the flexible OLED display market. Meanwhile, we believe that Samsung has been at least 2 years ahead of its competitors using this type of monitor, “said Rod Hall.

According to Bussiness Insider, the incident caused controversy. Will Apple be behind in the market of future phones? History has proved this to be completely true.

Has the 2010 history been repeated?
At the Mobile World Congress 2019 in Barcelona, ​​the phone seems to be the most talked about topic. The device is smaller than the iPhone XS, but when opened, it looks like a book. Users can easily fold the screen into (Samsung Galaxy Fold) or go out (Huawei Mate X).

Back in the past, in 2010, Samsung announced and traded a phone with a large screen (phablet). This step was despised by Apple. “You can’t hold it in your hand. No one will buy it, ”said Apple’s legendary CEO, Steve Jobs.

But in 2013, Apple realized that Steve Jobs was wrong. The company’s confidential documents showed that iPhone sales were slower than the market in the context of all other phones selling well.
Maybe, Galaxy Fold and Mate X were only incomplete testing products. But the future they bring cannot be underestimated. Slimmer, easy folding, higher battery capacity and cheap price. That is the challenge that Apple must face.
Samsung has created phones that are more aesthetically pleasing than the iPhone. Therefore, it is likely that they will repeat their success with the Galaxy Fold folding screen phones.

Previously, when Apple missed the big screen trend, it took Apple 4 years to catch up with Samsung. Currently iPhone sales are declining and there is no indication that the new iPhone model will appear. Therefore, experts wonder when Apple will catch up with Samsung on the front screen fold.

Folding screen smart phone will be the game changer in 2019

In addition to offering a completely new look, the folding screen smartphone can help to recover the sales figures of smartphone companies which have the tendency to decline over the years. At the 2018 Software Developer Conference, Samsung introduced the company’s first folding smartphone prototype. The phone is called the Galaxy F.

Smartphone makers have shipped 355.2 million smartphones in the third quarter of 2018, reduces 6 percent from the same period of last year, and the fourth quarter also decline, according to market research firm IDC.

Samsung is also facing many difficulties as its sales drop 13.4 percent to 72.2 million units. Samsung is facing competitive pressure from its rivals to maintain the top position in the mobile market, particularly Huawei, which is in second place and is going to take the lead position. Thus, a special phone like the Galaxy F will become a powerful weapon to help the company continue to maintain its current position.

Meanwhile, Apple is considered one of the companies that support the 5G network on their final models. Previously, 4G smartphone was launched in 2010 but in 2012 “new apple” equipped with 4G technology on the iPhone 5.

So, most likely Apple will be equipped with 5G technology on the iPhone model in 2020. Many people said that Apple does not want users to complain about the limitations of the modem or lack of coverage in the early stages.
