How to enable APP trust authorization on iPhone 13_Tutorial on setting up trusted devices on iPhone 13

The resolution of the iPhone 13 is not 2K; the 2K resolution is "2560*1440", and the resolution of the iPhone 13 is "2532x1170", so it is not 2K. Apple 13 is an i smartphone released by Apple on September 15, 2021, Beijing time. It uses a 6.1-inch OLED screen with a screen resolution of 2532x1170 pixels, a screen brightness of 800 nits, and a peak brightness of 1200 nits in HDR mode. special.

1. Select to enter the phone’s settings and click [General]. 2. Select Device Management as shown in the picture. 3. Find the file you have not authorized and click on it. 4. Select Trust on the negotiated interface.

Set the focus for your subject Improper focus is one of the common causes of blurry photos, and is also affected by light. Most people usually shoot with autofocus, and the results are usually pretty good. However, the autofocus can sometimes disappoint, resulting in images similar to the photo above. For best results, you can touch the screen in the iPhone's built-in camera app to set the focus manually. Sufficient light Sufficient light will not only allow you to get clearer photos, but also improve the quality of the photos. Whether you are shooting landscapes or portraits, you should ensure that there is sufficient light under the iPhone lens. When the shutter is open for a longer time, the movement may be slower. Too much will lead to blur. Generally, the scene should be carried out in a place with sufficient indoor light or a place with sufficient natural light outdoors.

The Apple 13 is equipped with the A15 Bionic chip. The A15 chip uses TSMC's 5nm process technology and integrates 15 billion transistors, which is a 27% increase in the number of transistors compared to the A14. The single-core performance is improved by 8%, and the multi-core performance is improved by more than 15%. The chip uses 2 performance cores + 4 energy efficiency The core consists of a 6-core design, in addition to a 4-core graphics processor and a 16-core neural network engine.

1. First click the camera to enter the photo taking interface. 2. There is a focal length option in the camera interface with the word [1X]. The user needs to click this button to proceed to the focal length selection. 3. Then turn to the value of [0.5], and the wide-angle lens is successfully turned on.

1. Click the camera icon on the mobile phone desktop and click the [1X] icon above the shooting button. 2. Slide to [0.5X] wide-angle mode.

1. Find the text messaging function on your phone. 2. First enter [DGVOLTE] to activate, then enter [Y] to confirm. 3. Then follow the text message prompts to find the call function in the settings. 4. Then click the button on the right side of VoLTE.

The Apple 13 chip is 5nm. The processor of the Apple 13 is the A15 Bionic chip. This chip is based on a 5-nanometer design and is manufactured by TSMC. It integrates 15 billion transistors, adopts a new 6-core design (2 large cores + 4 small cores) and has a 4-core GPU + 16 Core Neural Engine. The A15 Bionic CPU has a 50% performance improvement, and the graphics performance has a 30% performance improvement. With the 16-core neural network engine, it can also achieve machine learning capabilities.
