>>3961858>I actually thought that I might be better of by selling my E-M5 and get a cheaper DSLR with multiples lenses (something that is compatible with vintage lense that are dirt cheap)Maybe, but you lose a lot of convenience and reliability with those, and the prices of good vintage lenses have been skyrocketing. I'd only bother with those if I specifically wanted the look, not to save money.
>With my phone I just had to use the second camera that was built in or manually zoom with my fingers to get the composition that I wanted.>This picture for exemple, not the best one but I had to use the zoom to get some elements out of the composition, I can't do that with my 20mm unless I try to crop the picture manually by editing it, but it always end up looking krooked.When you pinch on your phone screen you aren't zooming, you're cropping, just like you would be doing with the Olympus. Most of the time you'll probably get better image quality cropping the Olympus than the phone, even though you're losing resolution in both cases.
Keep shooting the 20mm and cropping for a little while longer. But every time you do, make a note of the crop factor. Use that to calculate what you need in terms of focal lengths longer than 20mm. Also be mindful of what apertures you need to get your shots. Important if you like shooting in low light or experimenting with blurry backgrounds. Zooms in your price range are usually not much brighter than f/4, so that might end up limiting you more than not having the ability to zoom. If you need wider focal lengths, do the same, but with your phone.
>I deleted ALL the pictures I have taken with my Olympus since I hated themDon't do that. Even if they are bad they contain useful information that will help you get better. If you take a bad photograph, have a de-briefing with yourself about what could have made it a good picture. Sometimes it's better gear, sometimes it's better technique, but whatever it is, it's a valuable exercise.
