>>3623429You haven't even told us what your weakness is but anyway, I assume it isn't an issue with the phone's performance so I'll recommend you go to youtube and search basic photo composition. If you're shooting landscapes then narrow your search to landscape composition, for portraits then portrait composition etc
Once you get that down and want to push your images for a bit more punch then you can use a very robust and simple to learn editor on your phone such as Snapseed. It's free and has many great features. Now go shoot and stop worrying.
