My device: Huawei Mate 10 Lite
I accidentally uninstalled the Themes app (the theme setter, not the theme downloader). The app was a Huawei's version and was installed as a system app. I don't have a Huawei account and haven't tried pursuing the "update and get it from Huawei" way. I would prefer this as a last resort solution (IF that is a possible solution).
I have looked everywhere online for a working Theme app's apk installer but to no success. Most versions don't get installed. Some give errors when installed with TWRP, some get installed but crash on launch. Is there a "universal" Themes app that works fine with most phones? If no, how or where do I get and install the Huawei's Themes app on my phone?
