YouTube can publish 4K videos. It does do minor compression but on anything 720p and above it could hardly be considered unwatchable.
Google Photos, if you select full size, doesn't compress video at all. On full size it uses your Google Drive space. If you select the unlimited free option, it scales down to 1080p.
In 2015 no operating system is sending video via MMS without compression. You keep saying android can't do it, but imply that Apple can. People using android are sharing millions of videos per day, just not via the worst options possible (MMS) - almost all of the social media and file storage options will allow users to share extremely high quality videos. These include Google+, Facebook, Facebook Messenger, YouTube, etc, etc.
You're seeing the same answers over and over because the desire to use MMS is the part that is broken in this process. Literally no one, Apple included, can do this. That is not a fanboy statement, it is a fact about MMS. So if you change your perspective question from "I only want MMS and want to send uncompressed videos and I incorrectly believe that Android is the only OS that can't do this" to "what's the best way to share videos?" - then all of the help people have been offering is worth something.
When we answer the question, over and over, and explain the details of why it works and then you dismiss the answers and reasons in order to restate your original question... Yeah, that comes off as a little trollish or like you don't believe those trying to help you.
Either way, the answers are in this thread, many times - either use a social media app or share a link. If you try to use MMS on any operating system, it will either send nothing or massively compress the file. This is because MMS has three file size limiters (app, device, carrier) and the smallest of the three is the largest file that will travel.
