I have an original mi2 and have unlimited internet access. I would like to know where the setting is to increase mms size limits. And if it is possible to get rid of the message "unsupported file format". It is very annoying how restrictive miui has become with data sizes. I guess the rest of the world isn't unlimited. I would like any help in this issue. It seemed a few years ago there was a modified mms.apk that would allow size restrictions changes. I been using miui since it pretty much was new and never had this issue until v5. Unless I cannot find the setting.
