Onda vi30 Fashion Edition system comes with its own software, which can be deleted for fear of deletion errors.
Can be deleted, of course, to get ROOT permissions. I suggest you use 360 optimizer (installed in a tablet), which has an item, system slimming, indicating which files can be deleted and which files are system files. If they are deleted by mistake, they can be retrieved in the recycle bin, which is safer. Hehe, you can try.
