the pics all uploaded ws taken from mobile all were unfiltered... some considerations can be taken... why all got rejected?

Your phone camera is capable of giving good enough quality for Adobe Stock. Just keep in mind that moderators will not accept photos that have issues with color exposer or focus.  As general rule YOU MUST: 

-Only shoot your photos in the highest raw format. (Ask Grok or the AI you prefer how to set that up.) 

If you’re a new shooter, be open minded to playing with video, (shoot in 4k), and make sure the anti shake feature is on. Shooting photos develops your eye, but video does too, just keep in mind you have less margin of error, and will require planning the beginning and end of your clips.

Getting a small tripod/flexible stand for your phone can also make a nice difference. 

Shooting video or photos with your phone requires good lighting for adobe Stock, so avoid back light, scenes at night or in the shade.

-Editing with your phone will leven if shooting in raw will likely damage the file enough to be rejected.

If you haven't subscribed to Lightroom, invest in it now, and if you can spend the $20 (in the US) also get Photoshop.

Two more things… The camera doesn't make a great photographer, that is something you must master.

Be curious of everything you see, spend a lot more time observing than taking your shots.

Share 3 of your favorite photos, DM if you’d like. Photography is not rocket science, but most people don’t pause to think about enough before shooting. But your love for photography is a fuel that is nourished with every shot you take… just know that practice makes better, and with photography that means shoot shoot shoot, and never stop.

Best of luck to you.
