I have Galaxy Xcover and when I take a photo of 2.3 resolution and try to send it to contact in text message, it says "Photo is too large. Packing up".
Is there a way to send a picture that large or do I have to use smaller resolution while sending them?
You're limited by the network's MMS capability. Most carriers won't allow multimedia messages larger than 300 kilobytes (and thus most messaging apps won't even let you try to send a message larger than that), so the image needs to be shrunk to fit under that file size limbo stick.
If you want to send a larger picture, you'll need to send it via a different method, such as an email attachment or a picture messaging service like Snapchat.
