Having issues saving pics from a text, some save small.

Photos sent via text (aka MMS) are reduced resolution to make a smaller file size and reduce data requirements. This is a general MMS system thing, not an Android thing. If you want to photos in the original quality, send/receive them by email or by cloud storage such as Google Drive or Dropbox.

 

Some people, like me, reduce pictures for sending. I reduce size and remove EXIF.
If sending an MMS, I run it through ImageShrink before even attaching it. If data connection is weird, a photo will get reduced to 640x480@72 dpi. It's usually 600x800 normally. Everything I have in Flickr is that size.

No one bothers to do so normally and having to wait until a 10MP pic opens in email is a pain if you have a poor connection. If it isn't instant, I'm gone.

Full size pics go in dropbox for family and friends.
