    VirtualXposed

    VirtualXposed

    Use Xposed without root, unlock the bootloader or modify system image

    Open VirtualXposed, click on the drawer button at the bottom of the home page (or long click the screen), add your desired APP and Xposed Module to VirtualXposed’s virtual environment. Note, all operations (installation of Xposed Module, APP) must be done in VirtualXposed, otherwise the Xposed Module installed won’t take effect. For example, if you install the YouTube app on your system (Your phone’s original system, not in VirtualXposed), and then install YouTube AdAway (A YouTube Xposed Module) in VirtualXposed; or you install YouTube in VirtualXposed, and install YouTube AdAway on the original system, or both of them are installed on the original system, neither of these three cases will work! Clone an installed app from your original system. (Click Button at bottom of the home page, then click Add App, the first page shows a list of installed apps.) Install via an APK file.

    KonaBess

    KonaBess

    A GPU overclock & undervolt tool for various Snapdragon chips

    KonaBess is a straightforward application designed to customize GPU frequency and voltage tables without the need for kernel recompilation. The application achieves customization by unpacking the Boot/Vendor Boot image, decompiling and editing relevant dtb (device tree binary) files, and finally repacking and flashing the modified image. The extent of improvement varies, with some users reporting a 25% reduction in power consumption in the graphics benchmark (4.2w->3.2w) after undervolting the Snapdragon 865. Actual improvement is chip-specific and contingent on stability requirements.
