Maybe it's a difference in hardware, but any pictures I send are almost unrecognizable unless it's like a persons head framed perfectly. Kids sporting events? Forget it. People a few feet away? Maybe if I blur my eyes a bit and use my imagination. These picture resolutions were ok 20 years ago, but they are not acceptable today no matter how you sugar coat it. My biggest gripe has always been my kids sporting events and sharing pictures/ with family. MMS
limits, at least in the US, are 300-600kb (varies by carrier) for messages (although some say up to 1024kb anecdotally), go compress your images to that size and get back to me, especially if the subjects in the picture are not close and/or are moving. Videos are MUCH worse, they are virtually unusable.
Tapbacks come out as text, which is horrible and not a workaround. Facetime doesn't work at all obviously. Now I'm not arguing very hard for tapbacks or facetime, although I do feel they are important to the topic and part of what is contributing to the subject of youth popularity and their decision to stay in Apple's walled garden. The group message issue is well known, sometimes they don't sync up or you don't receive group messages.
