How to Protect Your Phone Screen: Cases, Glass and Habits

By OneTechPro · Updated November 10, 2026 · General guidance, not a diagnosis

What a case can and cannot do

A case mostly protects the corners, the edges and the back. Most cracked screens start from a drop on a corner or a flat landing face-down, so the shape of the case matters more than how thick it looks.

Look for a case with a lip that rises slightly above the screen. When the phone lands face-down, that lip takes the contact instead of the glass. A case that sits flush with the screen does very little for the front of the phone.

• Make sure the case fits your exact model, with no loose corners that let the phone shift inside.
• If you use a folio or wallet case, keep cards, coins and other hard objects out of the part that closes over the screen. A lump pressed against the glass in a bag can do damage.
• Take the case off now and then and clean it. Grit trapped between the case and the phone can scratch the body over time.

Are glass screen protectors worth it?

For most people, yes. A glass protector is a sacrificial layer. It can take scratches and sometimes absorb part of an impact, so the protector cracks and the screen underneath does not. Replacing a cracked protector is much simpler than replacing a screen.

There are limits. A protector will not save a phone from a hard drop on concrete, and a thin film protector mostly guards against light scratches rather than impacts. Some protectors can also make touch feel different, or get in the way of a fingerprint reader built into the screen or the sensors near the top of the phone. Choose one made for your model, and check that it leaves room around the camera and sensors.

If you apply one yourself, do it somewhere with little dust, wipe the screen completely clean first, and line it up before you press it down. Dust trapped underneath shows up as bubbles that are hard to get out. If a protector is cracked, replace it. Sharp edges can catch your fingers, and a damaged protector no longer protects.

Everyday habits that prevent cracks

Many cracked screens come from routine moments rather than dramatic drops. A few small changes cover most of them.

• Keep your phone in its own pocket or bag compartment, away from keys, coins and anything gritty. Fine sand and dust scratch glass more than you would expect.
• Avoid carrying it in a back pocket. Sitting down puts pressure on the screen and the body.
• Do not set it near the edge of a table, counter, couch arm or car seat, where a bump can send it to the floor.
• Be careful when using it in bed or on a couch. Phones are often dropped onto faces, floors and hard bedframes in those spots.
• Use a secure mount in the car rather than leaving the phone loose on the dash or seat.
• Clean the screen with a soft microfiber cloth. Skip harsh chemicals and abrasive wipes, which can wear down the coating on the glass.
• Do not leave your phone in a hot car or in direct sun for long stretches. Extreme heat is hard on the whole device, not just the screen.

When to bring your phone to OneTechPro

If your screen is already cracked, has dead spots, or no longer responds to touch the way it should, bring the phone to our shop at 4920 Flat Shoals Pkwy, Ste 104A in Decatur. No appointment is needed. Walk in during opening hours, or call or text first if you prefer.

We inspect the phone first, then tell you what it needs and what it costs before any work starts. You decide whether to go ahead. Repairs carry some risk, including possible data loss and effects on features like Face ID or Touch ID, so back up what you can before you come in and bring your charger and passcode if you have them. Repairs have a 30-day warranty from pickup on the parts and workmanship, but it does not cover physical damage or water damage. That is one more reason to put a good case and protector on a phone after a screen repair. See our Terms of Use for details.
