Disadvantages of Apple's mobile phone
1, the signal is not good, which is an old problem and has not been improved so far, especially in high-rise buildings, underground garages, high-speed rail, densely populated areas and other places, the signal of Apple mobile phones is obviously not as good as other mobile phones.
2. When using 4G or 5G, the network speed is slow, and Apple's 5G network speed is not as fast as Android's 4G, which is also a problem derived from weak signal ability.
3. High radiation is harmful to health. This is another problem caused by weak signal ability. Want to know more about Baidu, I would like to ask "Apple's mobile phone radiation exceeds the standard", and there are many results.
4. the screen is dazzling, which is the other side of apple's screen display effect. In order to pursue better display effect, Apple adopted the method of improving brightness and contrast, but this method is extremely bad for eyes and eyesight, especially for children. You should avoid using this high-brightness and high-contrast screen without shielding harmful blue light.
