wtf is oneims?

OneIms is a helper app for Google Pixel phones that focuses on IMS, the technology behind calling features like VoLTE, VoWiFi, and VoNR. The project explains that Pixel phones sometimes struggle to properly connect these calling features with a phone carrier's network, even when the hardware and plan both support them. OneIms tries to fix that by giving users a single app where they can check, configure, and repair these settings instead of digging through hidden Android menus or using command line tools. This repository only shares the README and APK release files. The source code itself is not open, so people who want to inspect or modify the code cannot do so here. Anyone with feedback or questions is asked to use the project's Telegram channel rather than looking for the code in this repository. There are two versions of the app that do the same job but activate their special permissions differently. OneKuku is a standalone build that handles activation inside the app itself, using a built in wireless debugging pairing process. OneIms Lite instead relies on a separate tool called Shizuku to gain the same access, which makes its installation file smaller. Users can install either one, or both at the same time if they want to compare them. Once set up, the app lets a person turn on or check calling features such as VoLTE, VoWiFi, VoNR, video calling, and cross-SIM calling, along with related display options like signal bars and 4G branding. It saves a snapshot of a working configuration so it can restore those settings automatically after a restart, and it includes a way to undo changes and put the carrier settings back to their original state if something goes wrong. The project is aimed at Pixel owners on Chinese carrier networks who have run into calling problems that Android's built in settings do not explain or fix. It assumes the reader already owns a Pixel phone and is comfortable installing an APK file outside the Play Store. No pricing or licensing information beyond the closed source note is given in the README.
