As smartphones continue to be updated, many once-familiar functions are gradually disappearing. Recently, Android Authority conducted a survey asking the public what features they miss most that have been abandoned by Android phones. Currently, more than 5,000 netizens have participated in the vote.

The survey results showed that the 3.5mm headphone jack ranked first with 27% of the votes.The elimination of the 3.5mm headphone jack has forced many people to turn to Bluetooth headsets, but charging problems and cumbersome pairing settings for Bluetooth headsets have made many people miss the convenience of wired headsets.

Some netizens pointed out: "Look at Sony's Xperia series and you will know that you can make a modern mobile phone with a headphone jack."

In second place is the removable battery, with a vote rate of 26%. In the past, most users would have extra spare batteries. When the phone runs out of power, it can be revived with a new battery.

However, most of today's mobile phones no longer allow users to replace the battery by themselves. Once there is a problem with the battery, users can only go to a repair center, which greatly increases maintenance costs.

The microSD card also received a support rate of 20%. Now if users need more storage space, they can only spend more money to buy more expensive models.
