Galaxy phones to stay away from, if you don't want to try your hand at the green line horror

Foldables are not line-proof as well… and the Galaxy Z Flip 4 is getting it!

Also, the same phenomenon manifested itself – just in pink, not in green – on Galaxy S20 and Galaxy S21 devices. Here, take a look:



That's not all, as even Apple is not spared. Here's the iPhone X which is also prone to getting an extra line on its display:



Google is not excluded from the party. In 2023, there were reports about the Pixel Fold getting the nasty lines, too.

OnePlus is not immune to the pesky display problem as well. You get the point.

The green line horror: why and how?

The green line issue primarily affects phones with AMOLED (Active Matrix Organic Light Emitting Diode) displays, although it's not limited to green, as seen above. You can have it in pink or in white.

Several things can cause green lines to show up and screw up your display:

• Hardware damage: Physical damage to the smartphone's display or internal components can lead to abnormal display behavior, including colored lines.
• Display driver issues: Problems with the display driver or related hardware can result in abnormal color rendering on the screen.
• Software glitches: Occasionally, software bugs or conflicts can cause display abnormalities, although this is less common compared to hardware issues.
• Manufacturing defects: Some smartphones may experience display issues due to manufacturing defects or quality control issues.
• Software updates: This sounds scary, but many users report the green line horror begins after they've installed an update…

Tips for potential solutions (don't hold your breath, though)

The only solution that works 100% of the time is to have your display unit changed. If you're out of warranty, or you're not feeling like paying a ton of money for an out-of-warranty service, here's what you can do:

• Restart the phone: Sometimes, a simple restart can resolve temporary software glitches causing display abnormalities.
• Perform a factory reset: If software issues persist, performing a factory reset (after backing up important data) can help eliminate software conflicts.

The above will work in only a handful of cases, so don't expect to magically sort out your problem. You can try, though.

Preventive measures:

• Use protective cases and screen protectors to minimize the risk of physical damage.
• Avoid exposing the phone to extreme temperatures or environments that could damage the internal components.
• Handle the phone with care and avoid dropping or mishandling it.

While there are troubleshooting steps and potential solutions, severe or persistent display issues may require professional repair or replacement. There's no way around it.

Which Galaxy phones to avoid?

When buying second hand electronic gadgets, one needs a fair share of luck.

If you like getting flagships on the budget, you're either looking at a killer deal (with present-time flagships, that's rarely the case) or you're buying a used phone.

If the idea of a green line bothers you a lot – frankly, who wouldn't be bothered by it – a Samsung-centric news site by the name of SamMobile suggests avoiding the following Galaxy phones from these series:

• Galaxy S20
• Galaxy S21
• Galaxy S22
• Galaxy Note 20

Of course, by being susceptible to the green line issue, the above series are not guaranteed to be flawed in every unit out there. Quite the contrary.

The number of affected units remains relatively low compared to the total sales volume of these product lines, which have collectively sold tens of millions of units.

The issue primarily impacts Samsung devices featuring Super AMOLED displays, and similar reports have surfaced regarding phones from other manufacturers using Samsung displays, as we've discussed above.

It's not the end of the world (yet it feels like it)

I've seen people use phones with screens so cracked, I wasn't even mad. Actually, it's kind of amazing.

That's on them, though: they dropped their shiny handset, or threw it against a wall. They're responsible for mishandling it.

Having a green line appear on your phone – be it a flagship or a budget-friendly friend – is not cool. I'm not getting into metaphysical debates as to why that's the case.

Instead, I'm keeping it strictly practical. That being said, having a green line on the screen will most certainly impact the resale value and marketability of your phone – in a negative way.

Having an extra line or two diminishes perceived reliability and limits the pool of potential buyers who prefer devices in optimal condition.

So, I wish you the best of luck: cracks and lines, not even once!

P.S. If you're out of luck and your phone displays a line, but it's still in warranty, insist that your service company changes your display. Don't accept anything less!
