There's a small issue

My phone unfortunately won't send pictures with your Samsung messaging app, it just shows me a little message in the bottom that says "failed to send" so I just fixed my storage until Google said I a had a lot of storage and I thought it was fine but I sent a picture to someone and it said "failed to send" again. So I thought that it was probably just a problem with Samsung Messages and not my storage, so I switched to Google Messages but it did the same thing, only difference is that it said "Not Sent". WHY IS THIS HAPPENING?!?

You probably need to be using Cellular Data. Usually Carriers won't send images with WiFi.

Hi iloveducks,

Please try to clear the Google Messages cache, go to Settings > Apps > Messages > Storage and select Clear cache and check if you are able to send messages.

Okay, thank you

I have the same issue. Seems to be with iPhones 🤔. Samsung phones receive everything without any problem. It was fine until 2 days ago.

As stated by @RedDogRabbit turn on your mobile data and then try sending or receiving pictures
