It has long been rumored that Samsung is developing a three-fold mobile phone called Galaxy Z Fold Tab. The aircraft may meet with us in the first quarter of 2022. The latest news shows that Samsung’s new trademark indicates that the machine does exist. Samsung’s “Galaxy Z Fold” trademark application submitted to the European Union Intellectual Property Office is classified as Class 9, and is described as a “smartphone, tablet.”

　　 This seems a bit unusual, because in Samsung’s previous “Galaxy Z” and “Z Flip” applications, there is no description of the so-called “tablet”. Therefore, we have reason to suspect that this three-folding screen called Galaxy Z Fold Tab may not only be as simple as a folding screen phone, it may be a tablet computer. However, judging from the relevant news, Samsung is still hesitant to show this new machine. I don’t know what kind of consideration this is.
　　 In addition, recent news about Samsung Z Fold 3 is also increasing. Outsiders believe that it may be Samsung’s next flagship folding machine. Based on previous revelations, the machine is expected to be equipped with an LTPO screen, with a screen refresh rate of approximately 120Hz; using a combination of 2215mAh+2060mAh dual battery cells, the rated battery capacity is 4275mAh. In addition, the machine may adopt a new folding form.>>>>>>>>>>>>>>>>>Mobile phone battery

On April 22, the evaluation agency DXOMARK announced the selfie lens score of the Samsung Galaxy S21 Ultra 5G. Based on the high-detail, wide dynamic range, and low-noise performance of this product in selfie photos, the Samsung Galaxy S21 Ultra 5G’s front camera scored 100 points.

　　 DXOMARK introduced that Samsung Galaxy S21 Ultra 5G can take selfies with good exposure even in low light conditions. And the front camera of the Samsung Galaxy S21 Ultra 5G has a very accurate autofocus function, so there is no need to repeatedly test the closest Selfie distance like a mobile phone with a fixed-focus front camera. However, this product will occasionally underexpose when the self-portrait distance is greater than 120 cm. Although the dynamic range of the photo is very wide, and can well capture the details of the subject, but in some monochrome test scenes, the white balance is always too cold. Since the depth of field of the front camera is quite narrow, the face far behind the closest subject may not be in focus. Therefore, it is recommended that users of the Samsung Galaxy S21 Ultra 5G take self-portraits as far away as possible.

　　 In addition, the level of detail of the Samsung Galaxy S21 Ultra 5G front camera is “amazing”, ranking among the top five in the DXOMARK text special test. Taking text photos in bright light, although there is a little noise, the style of the Samsung Galaxy S21 Ultra 5G front camera is to prioritize detail preservation rather than noise reduction.>>>>>>>>>>>>>>>>>Mobile phone battery

On April 21, according to GSMArena, Apple will push iOS 14.5 and iPadOS 14.5 to iPhone and iPad users next week. This update will add many new features to the system, including an App Tracking Transparency feature for advertising.

　　 When a user uses an iOS 14.5 device to open the APP, if the advertisement in the APP tries to track and collect user usage data, the system will automatically pop up a prompt message asking whether the user is allowed to grant the permission to collect data from the advertisement. Many companies that earn revenue through digital advertising have stated that this feature will reduce the efficiency of targeted advertising and lead to a decrease in related revenue.

　　 But Apple has also mentioned that all apps must support App Tracking Transparency from April 26, or apps that violate the new policy will be eliminated. It is worth noting that the purple version of iPhone 12, iPhone 12 mini and iPad Pro just released will be pre-installed with iOS 14.5 or iPadOS 14.5.>>>>>>>>>>>>>>>>>Mobile phone battery

On April 20th, Tianfeng International analyst Ming-Chi Kuo recently released a report that the coverage of global 5G millimeter wave infrastructure will increase significantly in the second half of 2021. Therefore, the iPhone 13 millimeter wave model released in the second half of 2021 The proportion will increase to 55%-60%. Previously, the iPhone 12 millimeter wave model was dominated by the US market, accounting for 30%-35% of the total. It is predicted that the iPhone 13 millimeter wave model will support more countries, such as Canada, Japan, Australia and major European mobile phone operators.
　　 More exact news about the Apple iPhone 13 series shows that the iPhone 13 Pro model will use Samsung’s 120Hz LTPO OLED panel. In addition, the iPhone 13 Pro product line will reduce power consumption by as much as 20%, which is likely to be attributed to the LTPO OLED panel and the more efficient A15 chip.

　　 It is rumored that Apple will use 120Hz LTPO OLED panels on iPhone 13 Pro and iPhone 13 Pro Max this year, while non-Pro iPhone 13 models will continue to use 60Hz OLED panels. Currently, Samsung has used 120Hz LTPO OLED panels on its flagship products Galaxy S21 and Note 20 Ultra devices.
　　It is expected that the use of the LTPO panel will enable Apple to dynamically adjust the refresh rate of the iPhone 13 Pro display to increase battery life, which will be similar to the ProMotion technology Apple has used in the iPad Pro series. In addition to using the 120Hz LTPO OLED panel, Apple is expected to use a thinner notch on the iPhone 13 series. There are rumors that the new version of the iPhone will also undergo other changes, including a faster and more efficient 5G modem, a larger battery, and an improved ultra-wide-angle camera.>>>>>>>>>>>>>>>>>Mobile phone battery
