Q: My right speaker is louder than my left speaker on my iPhone 7 plus. is this normal

Hi

If you are referring to the two speaker grilles at the bottom of your iPhone, note that there is only a speaker on the right hand side - the left side does not house a speaker.

If you are referring to the balance of volume between the receiver / earpiece speaker and the bottom speaker:

• Go to: Settings > General > Accessibility.
• Scroll down to check and adjust the audio volume balance slider.

The second speaker is the earpiece if you listen to a youtube or some of your music video you will here it coming out from there and the other speaker on the base. The other space where the 3.5mm headphone jack was is now a barometric vent. By making the iphone 7 water resistant and sealing up everything they needed to use that space to make the barometer accurate.

One speaker is in the receiver / earpiece (where you hold your iPhone to your ear - see "E" on the diagram below).

The other is under the grille on the right hand side at the bottom of your iPhone (see "L").

There is no speaker under the grille on the left hand side at the bottom of your iPhone.
