My IPhone volume keeps on increasing

Hello Astro_space,

We have a great support article that might help with this. Please take a look at it here: If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support. These steps may also help with the volume issues you are experiencing. Follow this guidance:

1. "Remove all screen protectors, films, or cases from your device. 
2. Check the speaker opening to see if it's blocked or dirty. On iPhone only, make sure that the receiver isn't blocked or dirty. 
3. If necessary, clean the speaker or receiver opening with a small, soft-bristled brush. Make sure that the brush is clean and dry.
4. Go to Settings > Sounds (or Settings > Sounds & Haptics), and drag the Ringer and Alerts slider back and forth a few times. If you don't hear any sound, or if your speaker button on the Ringer and Alerts slider is dimmed, your speaker might need service.
5. If you hear sound, try making a call with your iPhone and turn on speakerphone. On iPad or iPod touch, make a FaceTime call. If you still can't hear, or hear static or crackling, then your network or reception could be the issue. Try to call again later, or from a different location."

We hope this helps. Let us know if we can assist with anything else at all. Take care.
