Google and Samsung built a tool to boost the gaming experience on your phone


That stutter in your favorite mobile game might not be your phone’s fault. It could be how the game was built. Google and Samsung just teamed up to help Android studios catch those performance problems before you ever hit download.

The result is Sokatoa, a GPU profiler announced March 10 by Samsung’s Austin Research and Development Center and Advanced Computing Lab. But Samsung didn’t build it alone. The tool was developed in collaboration with Google and LunarG, a company deeply involved in Vulkan graphics development.

The tool is aimed at Android game developers, though anyone building graphics-heavy apps for the platform can use it. It works across different hardware too, supporting Samsung’s Xclipse GPU along with Qualcomm and ARM GPUs found in most other Android devices. The goal is better games, more stable frame rates, and fewer rendering headaches for the teams making them.

What makes Sokatoa different

The breakthrough here is something Samsung calls “multi-frame GPU profiling.” Most existing tools let developers peek at a single frame of rendering, which catches obvious glitches. But the nasty bugs, the ones that cause random stutters or frame drops every few seconds, hide across multiple frames.

Sokatoa lets engineers step through several frames at once. They can watch rendering behavior unfold over time, spotting patterns and intermittent issues that single-frame captures simply miss. Studios can edit shaders, the small programs that handle lighting and effects, and instantly replay the workload right on the device. That fast iteration loop means teams test fixes, compare results, and move on in minutes instead of hours.

What early testers are saying

The team put Sokatoa in front of real developers before launch, and the feedback suggests it actually solves problems.

Graphics engineers at Supercell, the studio behind Clash of Clans, have tested it since the first beta. One engineer highlighted a simple but powerful feature: viewing two traces side by side. Visual comparison helps the team isolate problem areas faster, especially when correlating data from a specific draw call to the final frame. Unity, whose engine powers a massive chunk of mobile games, also gave Sokatoa a spin.

What this means for your next game

Sokatoa is available now. Samsung hasn’t shared specific pricing or download details in the announcement, but the profiler is positioned as a direct answer to the frustrations Android studios face when optimizing graphics. The involvement of Google and LunarG suggests this tool could become a standard part of the Android development ecosystem.

Watch for games built or updated after developers get comfortable with the profiler. Early access feedback from Supercell and Unity suggests performance improvements could show up in titles already in development. And because it works across Qualcomm and ARM GPUs, the benefits shouldn’t be limited to Samsung devices.

Spotify aims to provide a consistent listening experience that uses minimal data. As a result, your audio quality might be less than ideal, especially if you’re using a pair of high-fidelity headphones or high-end speakers. Here’s how to fix that.

Switch audio streaming quality to Very High or Lossless

The default audio streaming quality in both the mobile and desktop Spotify apps is set to Automatic, which usually keeps the audio quality at Normal, which is only 96 Kbps. Even though Spotify uses the Ogg Vorbis codec, which is superior to MP3, OGG files exhibit slight (but noticeable) digital noise, poor bass detail, dull treble, and a narrow soundstage at 96 Kbps.

Even worse, Spotify is aggressive about adjusting the automatic bitrate. Even though 4G is more than fast enough to stream high-quality OGG files, even with a weak signal, Spotify may still drop the quality to Low, which has a bitrate of just 24 Kb/s. You will notice such a sharp drop in quality, even on a pair of bottom-of-the-barrel headphones.

To rectify this, open the Spotify app, tap your user image, open “Settings and privacy,” and tap the “Media Quality” menu. Once there, set Wi-Fi streaming quality and cellular streaming quality to “Very high” or “Lossless.”

I recommend setting cellular streaming quality to Very high and reserving Lossless for Wi-Fi, since lossless streaming is very data-intensive. One hour of streaming lossless files can take up to 1GB of data, as well as a good chunk of your phone’s storage, because Spotify caches files you’re frequently streaming. Besides, you’ll struggle to notice the difference unless you’re listening to music on a wired pair of high-end headphones or speakers; wireless connection just doesn’t have the bandwidth needed to convey the full fidelity of Spotify lossless audio.

You might opt for High quality if you have a capped data plan, but I recommend doing so only if you stream hours upon hours’ worth of music every single day over a cellular network. For instance, I burn through about 8 GB of data per month on average while streaming about two hours of very high-quality music over a cellular network each day.

How Audio Compression Works and Why It Can Affect Your Music Quality

Feeling the squeeze when listening to your favorite song?

Set audio download quality to Very high or Lossless

If you tend to download songs and albums for offline listening, you should also set the audio download quality to “Very high” or “Lossless.” This setting is located just under the audio streaming quality section.

If you’ve got enough free storage on your phone, opt for the latter, but if you’d rather save storage space, set it to Very high. You’ll hardly hear the difference, but lossless files are about five times larger than the 320 Kb/s OGG files Spotify offers at its Very high quality setting, and they can quickly fill up your phone’s storage.

Adjust video streaming quality at your discretion

The last section of the Media quality menu is Video streaming quality. This sets the quality of video podcasts and music videos available for certain songs. Since I care about neither, I set it to “Very high” on Wi-Fi and “Normal” on cellular, but you should tweak the two options at your discretion because songs sound notably better at higher video streaming quality levels.

If you often watch videos over cellular and have unlimited data, feel free to toggle video quality to very high.

Make sure Data Saver mode is disabled

Even if your audio quality is set to Very high or Lossless, Spotify will switch to low-quality streaming if the app’s Data saver mode is enabled. This option is located in the Data saving and offline menu. Open the menu, then set it to “Always off,” or choose “Automatic” to have Spotify’s Data Saver mode kick in alongside your phone’s Data Saver mode.

You can also enable volume normalization and play around with the built-in equalizer

Last but not least, there are two additional features you can play with to improve your listening experience. The first is volume normalization, which sets the same loudness for every track you’re listening to. This can be handy because different albums are mastered at different loudness levels, with newer music usually being louder.

Since I’m an album-oriented listener, I keep the option disabled. I can just play an album and set the audio volume accordingly, and I don’t really mind louder songs when listening to playlists, artists, or song radios.

But if you can’t stand one song being quiet and the next rattling the windows, visit the Playback menu, enable “Volume normalization,” and set it to “Quiet” or “Normal.” The “Loud” option can digitally compress files, and neither Spotify nor I recommend using it. This also happens with “Quiet” and “Normal,” since both adjust the decibel level of the master recording for each song, but the compression level is much lower and extremely hard to notice.

Before I end this, I should also mention that you can access the equalizer directly from the Spotify app, where you can fine-tune your music listening experience or pick one of the available equalizer presets. If your phone has a built-in equalizer, Spotify will open it; if it doesn’t, you can use Spotify’s. On my phone (a Samsung Galaxy S21 FE), I can only use One UI’s built-in equalizer.

To open the equalizer, open “Playback,” then hit the “Equalizer” button. Now you can equalize your audio to your heart’s content.


Adjusting just a few settings can have a drastic impact on your Spotify listening experience. If you aren’t satisfied with Spotify’s sound quality, make sure to adjust the audio before jumping ship. You should also check the sound quality settings from time to time, as Spotify can reset them during app updates.​​​​​​​
