Why Are Phone Manufacturers Removing the Headphone Jack and MicroSD Slot?

Not long ago, every phone had a 3.5mm headphone jack and most Android phones had a microSD card slot. Today, both are rare on flagships and increasingly missing from mid-range phones. Manufacturers give technical reasons, critics point to business motives, and the truth is a mix of both.

Why the headphone jack disappeared

1. Internal space

The jack and its surrounding module take up surprising depth inside a thin phone. Removing it frees room for bigger batteries, haptic motors, larger camera modules and speakers.

2. Water and dust resistance

Every opening is a weak point. Fewer ports make IP68 sealing easier and cheaper.

3. Thinner designs

A 3.5mm jack sets a minimum thickness at the phone's edge.

4. The wireless audio business

Wireless earbuds became a huge, profitable accessory category. Removing the jack pushed many people towards them.

5. USB-C audio

Audio can go through the USB-C port with a DAC (digital-to-analogue converter) dongle, so manufacturers argue the jack is redundant.

Why microSD slots disappeared

1. Speed

Internal UFS storage is many times faster than microSD. Apps installed on cards run slowly, and slow cards can cause camera lag with 4K video.

2. Security and encryption

Modern file-based encryption and app sandboxing work more cleanly with internal storage.

3. Space and sealing

Like the jack, the slot uses space and adds an opening.

4. Cloud services and storage tiers

Selling higher storage models and cloud subscriptions is profitable. Without a slot, buyers pay more for 256GB/512GB versions or cloud plans.

Which phones still have them?

  • Headphone jack: common on budget and mid-range phones (many Samsung Galaxy A, Motorola Moto G, Xiaomi Redmi, Realme, Sony Xperia models).
  • microSD: mostly budget/mid-range Android, rugged phones, and some Sony models.

Always check the spec sheet. Some mid-range models have one but not the other.

Workarounds

Missing Workaround
Headphone jack USB-C to 3.5mm DAC dongle, USB-C earphones, wireless earbuds
microSD Buy a higher storage tier, cloud storage, USB-C flash drive, portable SSD

Tip: a good USB-C DAC dongle can actually sound better than many built-in jacks.

Video explanation

Summary

Manufacturers removed jacks and slots for space, water resistance, speed and design, and it also nudges buyers toward wireless audio, bigger storage models and cloud plans. If they matter to you, choose from mid-range and budget lines that still include them.
