The functions of mobile phones are similar. Now the functions of mobile phones are very developed, so some mobile phones only make some changes in appearance or pixels when they are updated. Many people don't care about these two points, so they don't always change their phones with the update of their phones. At present, most people use their mobile phones to chat with others and watch some news by brushing videos. This function can be implemented on every mobile phone. Basically, they will not change their mobile phones when they are still available. People who really have very high requirements for pixels will choose to buy a good camera to shoot. The pixels of mobile phones can't meet their requirements at all, and they won't change their mobile phones because of pixel upgrade.
The price of mobile phones is generally high. Although it is very common to use only mobile phones now, the price of new mobile phones is still relatively high. The price of ordinary mobile phones is also around 3,000 to 4,000, and some larger brand mobile phones are around 5,000 to 6,000. The price of such a mobile phone has discouraged many people. Many people don't understand the hardship of making money when they are in college, so they will keep exchanging their parents' money for mobile phones. However, after they earn their own money at work, they are embarrassed to ask their parents for money to change their mobile phones, so they will not follow suit, and the money they can use will always be used. When they grow up, they are more willing to keep the money to repay their parents.
Cell phones all look the same, so there is no need to change them. Nowadays, the appearance of smart phones is almost the same every time they are updated, and there is nothing new, so others simply don't know what type of mobile phone they are when they put a mobile phone case behind them. Now everyone is using smart phones, and they don't care much about what brand to use. Without contrast, they won't always think about change.
