Quick answer
Import the quiet video from Photos.
Raise the audio level in small steps.
Check the loudest speech or impact sound.
Use EQ if the dialogue needs more presence.
Export a new louder video when it still sounds natural.
Why a dedicated app helps
Video volume problems are usually audio problems. A dedicated app lets you edit the sound track instead of only changing the phone speaker output.
What to test first
Compare the target clip with another video at the same device volume. If only one clip is quiet, it is probably the file itself that needs fixing.
How to keep speech clear
When dialogue is the priority, reduce low-frequency rumble before pushing the overall gain higher. That usually gives a cleaner result than brute-force amplification.
