Which mobile phone features are amazing in your memory, but then disappeared?

The rapid development of mobile phones has caused some functions to disappear, and has also caused the emergence of many new things. Some useful functions have been abandoned with the development. To take stock, I think some are practical but true. Abandoned functionality.

Second screen

This feature has actually appeared in the era of original feature phones. The most memorable thing is that there is a battery indicator on the front of the flip phone. The function of the time screen is that you can check the current time without turning on the screen, which can be said to be much more convenient. Later, with the emergence of smartphones, this function no longer existed. It was not until the later LG V20 that we saw the use of the secondary screen on smartphones. It can store commonly used apps, add contacts, and check notifications without turning on the screen. It can be said to be a little assistant for the home screen, but it is a pity that LG itself has not done a good job in promoting it, and consumers I don’t seem to like this machine, not only because its secondary screen function is relatively useless, but also because it is far from a flagship phone in other aspects.

Removable battery

Imagine if your phone suddenly ran out of power, and you are now in a place where you need a phone but there is no place to charge it. At this time, replace it. The last spare battery is immediately resurrected with full health, and it is a good thing to recharge the battery that was just replaced when you return to a place where it can be charged. This feature was still retained at the beginning of the smartphone era. It was not until the introduction of metal integrated fuselages that the original removable battery design disappeared. Because the original plastic body was still removable, but now the metal body has become integrated, and the back cover cannot be opened. Naturally, the design of the removable battery has been cancelled. But is this design still available? In fact, there are still some, yes! It’s LG again, the previous generation’s flagship LG G6. Even though it uses a metal body, the highlight is that its chin is detachable, the battery can be replaced, and various official accessories can be added to improve the functionality of the phone. However, Unfortunately, this design is also not very easy to use, so this design has been canceled in the next generation. (But I still have to thank LG for every innovation in the mobile phone industry)

3.5MM headphone jack

There are quite a few mobile phones that retain headphone jacks, but it is possible In the future, there will be fewer and fewer mobile phones with headphone jacks. Since the headphone jack was canceled on the Iphone7 (LeTV canceled it first, but it is not as influential as Apple). For some reason, other manufacturers have also followed suit. It’s a way of saying, “In a space where space is precious, such as mobile phones, canceling the 3.5MM headphone jack can save more space and improve the user experience.” I originally thought that basically few manufacturers would follow suit. Yes, I didn’t expect it to be so influential that many flagship models have canceled the 3.5MM headphone jack. If the headphone jack is removed like Xiaomi 6 or Iphone 7 to add waterproof function, then what is the purpose of those phones without waterproof function? It can only be said that it was canceled following the trend. This jack is the feature I least want to let disappear at the moment, but according to the momentum, mobile phones without a 3.5MM headphone jack may no longer exist in the future. Let me mourn for a minute of silence for the headphone jack.
