Keep the lens clean
Dirty lenses are a common cause of blurred photos and reduced sharpness. Just wipe lightly with a soft cloth before shooting, photo quality can be significantly improved without much editing.
Take advantage of natural light
Natural light helps photos have harmonious colors and better depth. The ideal time is early morning or late afternoon, when the light is soft and does not cause sharp shadows like noon.
Do not zoom with phone cameras
Digital zoom (photofocus) reduces image quality, easily blurred. Instead of zooming, you should move closer to the subject or take a normal shot and then cut (crop) when editing to maintain sharpness.
Tap to focus and adjust light
Touching the screen helps to determine the correct focus area. At the same time, the photographer can pull the light bar to avoid the photo being too dark or overshot, helping the photo to be more balanced.

Try different shooting angles
Do not only shoot at eye level. Shooting angles from low to high, from high to low or slightly tilted can create novel visual effects, helping the photo to be less boring and more highlighted.
Lightly edit photos after shooting
Basic editing tools such as increasing brightness, adjusting contrast, and color balance can help photos become significantly more beautiful. However, adjustments should be moderate to maintain naturalness.
