Hidden Settings For MIUI is a Tools app designed to help users reach settings and options that its description says are hidden inside the device's default settings app. According to the listing, it can turn pre-installed apps off, adjust how other apps behave, and provide hardware testing tools. The description places particular emphasis on MIUI, the Xiaomi interface, while also naming several other manufacturers. The record lists version 6.19.
Access to hidden settings
The app's central purpose, as described, is to bring together settings that are otherwise difficult to find. The listing says it can help users identify menus that the publisher has limited and reach advanced options through shortcuts the app sets up. It also states that some special features can be unlocked this way. The description does not explain which menus are included or how each one is reached, so these claims should be read as the developer's own description rather than independently verified behavior.
Managing pre-installed apps
A major use described in the listing is disabling default apps that users do not need. The description says this can free storage space and give more control over the device. It also mentions removing unnecessary pre-installed apps to save RAM and reduce background activity, and it claims that removing unneeded features can help battery life. These benefits are stated by the listing and have not been measured here.
Customizing app behavior and network options
The app is described as able to change the default behavior of installed apps. Its private DNS option is presented as a way to block ads and limit tracking, and the listing also mentions a setting that enables VoWifi even when a carrier does not support it. A further option changes the cell band mode to improve network connection. The description does not state which devices, carriers, or Android versions these network options work with, so users would need to confirm support on their own hardware.
Hardware testing and display settings
The listing mentions a range of tools for testing and troubleshooting hardware functions, which it says can help detect issues. It also claims the app can raise the display refresh rate from 90Hz to 120Hz for smoother gaming. This is presented as a feature claim, and the description gives no further detail about how it is applied.
Device support and limitations
The description says many devices will support these features and names Xiaomi (MIUI), Huawei, Samsung, Poco, Oppo, OnePlus, and LG. It does not provide a list of tested models or a minimum Android version. The minimum OS value supplied with this record is not a valid version number, so it is not used here. The conclusion refers to user caution, but the listing does not describe specific safeguards for changes made through the app.
