🚨 Technician POV: 5 Phones We'd Avoid Buying Used in Bandar Baru Enstek

🇬🇧 English

Not every used phone is a bad purchase.

In fact, buying an older flagship can sometimes give you much more phone for your money.

But there are certain models where we'd stop and think twice before handing over our money.

So, from a technician's point of view, here are 5 types of phones we'd be extremely careful about buying used in Bandar Baru Enstek.

🥇 1. POCO X3 Pro

🚨 The motherboard concern

The POCO X3 Pro became extremely popular among gamers because of its performance-to-price ratio.

But its reputation among repair communities took a hit because of reported motherboard failures.

Symptoms can include:

• Sudden shutdown
• Failure to power on
• Boot problems
• Random restarting
• No display

That doesn't mean every X3 Pro will fail.

But if we found a heavily used X3 Pro with an unknown history?

We'd think twice.

Especially if the price seems suspiciously cheap.

🥈 2. Samsung Note 20 Ultra

🟢 Amazing phone... but inspect the display

The Note 20 Ultra still has impressive specifications.

S Pen.

AMOLED.

120Hz.

Great cameras.

But when buying one used, the display deserves serious attention.

Check for:

• Green lines
• Pink lines
• Burn-in
• Flickering
• Touch problems

If the screen already shows abnormalities, we'd want to know the repair cost before buying the phone.

🥉 3. iPhone 12 Mini

🔋 Great size, questionable battery life

We actually like the 12 Mini.

It's compact.

It's fast.

It's comfortable to use.

But the battery is the obvious weakness.

And in 2026, the original battery is already several years old.

If you're a heavy user, we'd be especially careful.

A cheap 12 Mini with poor battery health isn't necessarily a bargain.

4. Older Foldable Phones

🦾 Amazing technology... complicated repairs

We love what foldable phones can do.

But buying an older foldable used is a different story.

We'd inspect:

• Hinge
• Inner display
• Crease
• Screen protector
• Touchscreen
• Outer display

One small problem can potentially become a much bigger repair.

If you're buying a used foldable because it's "crazy cheap", that's exactly when we'd inspect it more carefully.

5. Heavily Repaired iPhones

🍎 The model isn't the problem. The history is.

An iPhone can look perfect from the outside while having a long repair history.

Before buying a suspiciously cheap iPhone, ask:

Screen replaced?

Battery replaced?

Face ID repaired?

Camera replaced?

Motherboard repaired?

Water damage?

A properly repaired iPhone can still be perfectly usable.

But if the seller can't explain what happened to the phone?

🚩 That's when we'd walk away.

🤔 So Are These Phones Automatically Bad?

No.

That's important.

We're not saying:

"Never buy these phones."

We're saying:

Don't buy them blindly.

A well-maintained phone with a clean history can be a great deal.

A heavily abused phone with hidden problems can be a nightmare regardless of the model.
