Should You Use a Screen Protector? The Truth About Tempered Glass
Every time someone brings in a phone with a smashed screen, we hear the same thing: “I kept meaning to get a screen protector.” It’s one of those things that feels optional until you’re staring at a web of cracks across your display and facing a repair bill.
So is a screen protector actually worth it, or is it just another accessory the phone industry wants to sell you? Here’s our honest take.
Modern Phone Screens Are Tough – But Not Tough Enough
Phone manufacturers have made huge advances in screen durability. Apple uses Ceramic Shield on recent iPhones. Samsung uses Gorilla Glass Victus. These are genuinely impressive materials that resist scratches far better than the screens of ten years ago.
But here’s the crucial distinction: scratch-resistant does not mean shatter-proof. Your phone screen might survive being in the same pocket as your keys without a mark. But drop it face-down onto a paving slab from waist height and that Ceramic Shield will crack just like any other glass.
Scratch resistance and impact resistance are two different things. Screen protectors help with both.
Types of Screen Protectors
Tempered Glass
This is what we recommend and what we sell in the shop. Tempered glass protectors are a thin layer of hardened glass that sits on top of your actual screen. They feel almost identical to the real screen – same smoothness, same touch sensitivity, same clarity.
The key benefit: when you drop your phone, the tempered glass protector absorbs the impact and cracks instead of your actual screen. It sacrifices itself. A cracked £10 protector that saved a £200 screen is the best money you’ve ever spent.
Plastic Film
The cheapest option, and you get what you pay for. Plastic film protectors are fine for preventing scratches – they’ll stop keys and coins from marking your screen. But they offer almost no impact protection. If your phone hits the ground hard, a plastic film isn’t going to save it.
They also tend to feel worse under your finger, pick up smudges more easily, and develop bubbles over time. We’d skip these.
Liquid Screen Protectors
These are marketed as an invisible coating that hardens your screen. You apply a liquid, let it dry, and supposedly your screen becomes more resistant to damage. The reality? There’s very little independent evidence that liquid protectors offer meaningful impact protection. They might add a marginal improvement to scratch resistance, but they won’t stop your screen from cracking in a drop.
If something sounds too good to be true, it usually is. Stick with tempered glass.
How to Tell if Your Screen Protector Saved Your Screen
After a drop, peel up a corner of your screen protector carefully. If the protector is cracked but the actual screen underneath is clean and undamaged – congratulations, it did its job perfectly. Peel the broken protector off, apply a new one, and carry on.
We see this regularly. Someone comes in convinced their screen is smashed, and it turns out the protector took the hit. It’s always a relief.
The Cost Argument
This is really what it comes down to. A decent tempered glass screen protector costs around £10. A phone screen repair costs £69 to £299 depending on the model. An iPhone screen replacement for a recent Pro model is at the top end of that range.
Even if a screen protector only saves your screen once over the life of your phone, it’s paid for itself many times over. It’s cheap insurance.
When a Screen Protector Won’t Help
We should be honest about the limitations too. A screen protector is not a magic shield. There are situations where your screen will break regardless:
- High drops onto hard surfaces – a phone falling from a balcony or the top of a ladder onto concrete is generating too much force for a thin protector to absorb
- Point impacts – landing directly on a sharp stone or the corner of a step concentrates the force into a tiny area, which can overwhelm any protector
- Edge impacts – if your phone lands on its edge or corner, the force bypasses the protector entirely and goes straight into the screen’s weak points
A screen protector significantly improves your odds in everyday drops – waist height, off a table, out of your lap when you stand up. For extreme impacts, you need a good case as well.
How to Apply a Screen Protector Properly
The reason most people get bubbles is dust. Here’s how to do it right:
- Find a clean, still environment – a bathroom after a shower is ideal because the steam settles airborne dust
- Clean the screen thoroughly – use the alcohol wipe and microfibre cloth that come in the kit
- Use the dust removal stickers – dab them across the screen to pick up any remaining particles
- Align the protector carefully – line up the speaker cutout and camera first, then lower it down from one end
- Press from the centre outward – use a card or the included squeegee to push any remaining air bubbles to the edges
Or – skip the hassle entirely and let us do it. We sell screen protectors at our shop in St Andrews and we’ll fit them for you properly. No bubbles, no misalignment, no fuss.
Our Recommendation
Yes, a screen protector is worth it. Specifically, a tempered glass one. It costs a fraction of a screen repair, it doesn’t affect how your phone looks or feels, and it genuinely works. We’ve seen it save screens hundreds of times.
Pair it with a decent case and your phone has the best chance of surviving whatever daily life throws at it.
