I'm going a little nuts here, I have an AT&T HTC One that I converted to a GPE phone, and for some reason, half of the photos I try to send via MMS appear on the other end with this message and no photo: one or more of the message components have been deleted by mms adaptation. either the message was too large or the components were unsuitable for your handset.
This usually only happens if the photo is large, but doesn't happen if I use the stock messaging app. I'm currently using hangouts, but has been reproduced on textra. I've swapped the Sim with my father's stock sense HTC one (4.2.2), and the photos send fine.
I literally have no idea what the problem is, or how to fix it, I've screwed around with APN settings, uninstalled and reinstalled hangouts. I'm at wits end, and my only guess is that there is something at the OS level that is problematic, something weird about hangouts on the GPE phone, or something on AT$T's end that doesn't like my phone being a GPE variant (also, the APN settings on the GPE phone didn't have the option for MMS profiles? The sense one did, and was set to WAP 2.0, maybe this is the problem?)
Any help or insight would be appreciated. If you are on a GPE HTC One or a converted to GPE HTC One and would like to help me out, try sending this image via MMS to another person, and tell me if it was successful and what carrier you're on (I'm on AT&T):
I just tried using a different GPE rom, and that didn't work either. I'm about to try a Sense rom and see what happens.
Thanks in advance!
