I am very sorry to hear your S21 is getting hot enough to melt your screen protector, and can understand how concerning this is. Whether you're using a phone, tablet, smart watch, or earbuds, all Galaxy devices have a set temperature range, where they operate at their best. While they may feel warm under certain conditions, like charging, this does not affect the device's lifespan or performance. However, if your devices get too warm, it could cause some issues. Use this guide to help keep your devices at their normal operating temperature: https://www.samsung.com/us/support/answer/ANS00076952/
