Because I didnt find such a thread all over internet, Ive decided to gather information about all the system apps that are present in Flyme OS 188.8.131.52 and which of them are safe to remove.
Please make a full nandroid backup before removing any of the applications.
Use at your own risk, I cannot be held responsible if you break your phone.
The list below describes all stock apks under /system/app and /system/priv-app. You can see this folder via RootExplorer or FileExplorer or the like, or see them through Titanium Backup, although they might be out of order and with different names (they will use the display name rather than apk name on Titanium). I personally use ES File Explorer for deleting system applications.
If you are deleting system apps manually with Root Explorer (for example) delete it´s respective .odex as well.
