The development of the mobile phone industry has not only brought us a lot of convenience (such as mobile phone payment, online shopping, etc.), but also made some of the once popular functions gradually disappear from the public's field of vision, and this has become the memories of many post-70s, 80s and 90s.
Next, let's take an inventory of the 5 good-use functions that have disappeared in the history of mobile phone development.
The first item: 3.5mm earphone jack
The last phone I used with a 3.5mm headphone hole was the Samsung S8+, which has now become very stuttering, but occasionally I still use wired headphones to listen to songs.
Functionally speaking, the 3.5mm earphone jack allows users to easily use wired headphones, as long as the mobile phone has power, it can be used all the time, unlike the current wireless Bluetooth headset, you have to charge the headphones to use.
Nowadays, the vast majority of smartphones have abandoned the headphone hole, and many mobile phone brands claim that the cancellation of the headphone hole is to improve the waterproof performance of the mobile phone, in fact, the subtext is to sell more wireless Bluetooth headsets.
After all, the waterproof performance of mobile phones is not a function that users often use, and the deletion of the headphone hole makes consumers have to pay an extra higher fee to enjoy the fun of listening to songs anytime, anywhere.
Item 2: breathing lamp
Breathing lights are now also abandoned by many mobile phones. It used to be standard on most smartphones as a very useful notification & reminder feature.
When the mobile phone receives messages, such as missed calls, social messages, and text messages, the breathing light of the mobile phone can flash rhythmically, and some mobile phones can also make the breathing light show different colors according to the different messages, that is, you don't need to unlock the phone at all, you can know what kind of information you have.
But since the mobile phone tends to the full screen design, the breathing light has begun to "die", after all, the existence of the breathing light will hinder the mobile phone to have a higher screen-to-body ratio.
The third item: removable battery
For removable batteries, the post-80s and post-90s are impressed.
In early smartphones, mobile phone users could easily replace the mobile phone battery, and even when buying a mobile phone, the store would provide additional batteries as a backup.
But soon, the design of the removable battery was replaced by a built-in battery, and when the user went out, he had to carry a charger or charging treasure to solve the battery life problem of the mobile phone.
Item 4: Expandable SD card slot
Earlier mobile phones generally did not have much memory, so the expandable SD card slot became a just-needed function. At that time, in order to store more pop songs in my phone, I deliberately bought a 16GB SD card.
By inserting an SD card, users can get more storage space, saving money on buying a high-memory version of the phone. Moreover, SD card as a storage medium, can not only be used on mobile phones, but also can be inserted into the computer with a card reader, which is very convenient.
Item 5: FM radio
This is a very unique feature, with this function on the mobile phone, countless people can listen to radio programs across the country without needing to connect to the Internet.
For many people, especially those middle-aged and elderly groups who do not have the time and conditions to pursue more frequent entertainment projects, and friends who love radio programs, FM radio is a very good companion.
Today's smartphones, basically can not see this function, in addition, now there are many forms of entertainment, a variety of short videos, social forms emerge endlessly, it seems that not many people can sit quietly and listen to the radio program.
