My ZTE Axon 7 suddenly began compressing pictures and gifs received via MMS to no more than 30 kb. Sent pictures and gifs appear fine on the recipient's phone. This happens when I'm using the default texting app Messaging as well as Google's Messages, Textra, Signal, etc. HOWEVER, the phone does not compress media received through WhatsApp. I've ruled out an issue with the Verizon network by switching SIM cards with my wife and sending a gif to her number, which is then received by my phone. The received gif is still compressed to 30 kb. I've performed several hard resets to restore all settings to factory, and nothing's worked. Can anyone here help troubleshoot this please? I'm running Android 7.1.1, kernel version 3.18.31, build number A2017UV1.1.0B35.
