Debunking the "Android AAC is bad" myth: Samsung S23 + Android 16 Spectral Analysis (SBC vs. AAC)

TL;DR: I tested the Bluetooth audio codecs AAC vs. SBC in order to proof the myth "Android AAC is bad" using a Sine Sweep on my S23 (Android 16) and Koss Porta Pro Wireless. Recorded via a Shure Beta 58A + RME interface.

The result: AAC (Image A) is clean up to 20kHz, while SBC (Image B) is a mess of aliasing and compression artifacts. I recommend using AAC, at least on Samsung phones.

Hey everyone,

I’ve been reading for ages that AAC on Android (especially Samsung) is supposedly "broken" or "trash," with some people even recommending sticking to SBC because of aggressive 14kHz low-pass filters or harsh compression artifacts.

I decided to put this to the test with my S23 (running Android 16) and a pair of Koss Porta Pro Wireless (the new version which supports AAC and SBC).

The Setup:

* Source: 44.1kHz WAV Sine Sweep.
* Recording: Shure Beta 58A directly against the ear pads, running into an RME interface. I threw a thick sweater over the whole thing to isolate the mic.
* Analysis: Spek (Spectrogram).

The Results (Check the images):

* Image A (AAC): Look at that clean line. The sweep goes all the way up to \~20kHz without any hard cut. The background is dark, meaning a very high signal-to-noise ratio and great dynamic range.
* Image B (SBC): This is where it gets messy. Notice the "ghost" diagonal lines (aliasing/intermodulation) and the "cloudy" noise floor between 0:24 and 0:36. That’s the codec struggling to handle the signal. This translates to that "metallic" sizzle or graininess you sometimes hear in high frequencies (cymbals, etc.).

My Conclusion: The old myth that Samsung/Android has a broken AAC implementation seems to be dead - at least on modern hardware/software.

AAC (Image A) is significantly cleaner, more precise, and has a much better frequency response than SBC (Image B). If you’re on a modern Samsung device, don't fear the "HD Audio" toggle. AAC is clearly the superior choice here.

What do you guys think? Has anyone else done similar measurements on other Android brands?

Android 16 on the Moto Edge is a total scam. I’m officially done with Motorola.

I just "upgraded" my Motorola Edge to Android 16 and I honestly feel like I’ve been scammed.

Motorola basically took the Android 16 kernel, slapped the old Android 15 skin on top, and called it a day. They completely stripped out Google's Material 3 Expressive UI—no new animations, no new clock styles, nothing. It looks and feels exactly like last year’s software.

But it’s actually worse than just being lazy:

Broken Network Reporting: Ever since the update, my status bar shows "No Signal" constantly on T-Mobile, even though my data is working. The OS literally can’t read the carrier data anymore.

The Battery Massacre: My phone is draining 15% an hour just sitting on my desk.

Throttled Charging: My "TurboPower" 68W charger now feels like a 10W brick. It took 4 hours to hit 50% today.

Hard-Locked OS: I’ve tried forcing the Expressive UI flags via ADB and Motorola has literally hard-coded the system to ignore them. You can't even customize the phone you paid for.

Is anyone else seeing this? I’ve been a Moto fan for years because of the "clean" software, but this "shell" of an update is planned obsolescence at its finest.

I’m already looking at the Pixel 10 or a Samsung. If Motorola doesn't want to support their customers, they don't deserve our money. Who else is leaving?

Is the Android Tax still a thing in 2026 or am I missing something?

So my story starts with trying to improve my Spanish with an app I invested in recently. I got Premium, and then was shocked to find out that the iOS version is packed with features that are simply missing on Android. e.g. missing 2 of their most advanced AI tuttors on Android because they are first released on iOS and only later will be on android. It feels completely unfair to pay the same premium price for what is essentially an inferior product. On top of the missing features, the Android version feels less stable. I actually found a bug in one of the tutors that makes the lessons difficult to complete. Apparently, this specific issue does not even exist on the iOS version. This isn't just a Praktika thing, either. Even Google’s own Gmail app still struggles with basic things on Android, while it works perfectly on iOS. Then you have Instagram, where the camera optimization and new "Edits" features always feel like they were built for iPhone first and ported to us as an afterthought.

Why is this still happening in 2026? Android has massive global market share and the hardware in our pockets is incredible now. Why do developers continue to neglect the Android versions of their apps years after the platform has matured? Is it a technical hurdle, or are we just an afterthought for these dev teams?

TL;DR: I paid for Praktika app premium but the Android version is missing features that iOS has. Why are developers still neglecting Android in 2026?

P.S. Mods if any of the posting rules are in breach please let me know, I have been part of this community for years and I plan on staying for many more.
