[Solved] On iPhone, How to Fix Low Ear-Speaker/ Earpiece Sound Volume During Phone Call

Problem: On iPhone, low ear-speaker/ earpiece volume during phone call even when volume is set to maximum.

Caused After: Sometimes after iOS upgrade or when something falls into the ear-phone cavity.

Devices: iPhone 3G, iPhone 4, iPhone 5, iPhone 6 (all variants).

Solution: As strange as it may sound, simply suck the earpiece/ ear-speaker cavity as hard as possible.

How it works: Possibly the earpiece moves back into right position.
