Android Authority Writer Frees 15GB on Samsung Galaxy Phone, Finds Native Tool Often Enough
An Android Authority writer reclaimed 15GB on a 256GB Samsung Galaxy phone after testing One UI Device Care, Files by Google, and SD Maid SE. The writer concluded that Samsung's built-in storage management and Android's background cache handling are enough for most casual users.
The writer began the cleanup after noticing that more than 200GB of the phone's 256GB storage was full. With about 50GB remaining, the writer wanted to avoid minutes-long videos of a son filling the rest. The test compared Samsung One UI's native Device Care storage suite, Files by Google, and SD Maid SE, a cleanup tool popular among power users. The writer ultimately recovered 15GB but said the result was smaller than expected because many large files were deliberately kept.
Samsung's native tool remained central to the writer's routine. The writer described long-pressing an app on the home screen, tapping the i icon in the top-right corner of the pop-up, tapping Storage, and then Clear cache as a habitual cleanup step. The writer called the native solution efficient, ever-present, and ingrained in daily habits.
Files by Google offered a different interface. The writer said its initial screen was plain and similar to other storage managers, but the Clean section, accessed through a three-line menu in the top-left corner, brought screenshots, unused apps, large files, recordings, and downloaded files into one place. The writer deleted some media files and duplicates that appeared there. Google's app also uses large text and prominent visual boxes, which the writer found intuitive, while the built-in tool sorts files into slightly more specific categories. The writer said one is not necessarily better than the other and that the choice comes down to personal preference. Files by Google can be a nice extra, the writer added, but it did not replace the native tool.
SD Maid SE produced a much smaller result. After granting full permissions, the writer cleared 17kB of superfluous data and 0 bytes of orphan files. The writer said the app did not fail; rather, the operating system and the tools already used had handled most cleanup. Still, SD Maid SE's settings showed deep customization options, including tracking log files, leftover APKs, and OTA update files to the root. The writer described it as a toolkit for power users who want byte-level control, but not a must-have for casual users.
The writer argued that Google and One UI have already covered most basic automated storage management. What remains for users, the writer said, is deciding whether to delete a 2GB video or a game that has not been played for a year. For many users, manual cache clearing or extensive file filtering appears to be a thing of the past.
The article traced that shift to changes in Android. The writer recalled poking around Galaxy Note Edge, Note 5, and Note 8 devices to find files to delete. Those phones were often close to running out of storage, and wiping junk and system caches could recover gigabytes. That is no longer the case, the writer said. Android now has a dynamic background cache quota at the OS level that automatically clears cached data when storage space is needed. Social media apps still use caches to speed up video loading and improve playback performance, but the writer said those caches are not kept for long. Samsung's Auto-Optimization also manages storage while the user sleeps, according to the article.
