With a replacement screen, a toolkit, and an online video, it is possible to replace a screen on your own. However, cell phone screens don't just pop off and back on. Screen replacement requires a very steady hand with several delicate ribbons and other pieces.

A good rule to follow: If repairing your phone costs half as much as buying a new one—or more—consider getting a new phone, especially if yours is more than a few years old. Remember, you can often trade in your old phone and apply that credit towards a new one, too. Let's do the math.

Whether you have an Android or iPhone, you can find instructions to replace your battery or screen, change out a headphone jack, remove the SIM card, and do many other tasks. Although you can find repair guides online, some repairs may need an expert; take your phone to a certified dealer if necessary.

A cracked Android phone screen might cost anywhere between $100 and $300 to repair. A DIY phone screen repair, on the other hand, may cost $15 to $40. An iPhone 11 screen replacement costs $199 for an iPhone 11 display, $279 for an iPhone 11 Pro display, and $329 for an iPhone 11 Pro Max screen replacement.
