WARNING - 99% OF "IT STOPPED WORKING" ERRORS ARE CAUSED BY timed out root requests after auto-updates, to use this app together with auto-update in Play, you MUST disable re-authentication in your superuser app.

WARNING - app generally only supports devices commonly available in the West. We will ignore requests for compatibility with random knockoffs and no name provider phones.

WARNING - multi-sim devices are not officially supported, though after version newer Qualcomm and possibly other chipsets should work. This does not mean everything will work on every phone. It means it MAY work on your phone. As a general rule more expensive will be more compatible. Stay away from Chinese devices, especially OEMs, they are likely to have custom RILs that we will never support. If you need this app and dual sim, contact us before you buy your next phone.
