The OnePlus Green Line Issue: What Users Need to Know

Many OnePlus smartphone users have reported seeing a mysterious “green line” running vertically down their displays. This OnePlus display issue shows up as a thin, bright green streak from the top to the bottom of the AMOLED screen​androidauthority. It’s not a software bug or an app glitch – it’s a hardware fault in the display panel. In practice, the green line is impossible to ignore: it stays lit as long as the screen is on and can ruin the viewing experience. Android Authority describes it as “a thin band of green color that goes from the absolute top to the bottom of the display”​. In short, if you see this green stripe, your OnePlus phone’s screen is damaged.

Why Does This Happen? (OnePlus AMOLED Problem)

The green line issue is a hardware problem affecting AMOLED displays, not just on OnePlus but on many brands. OnePlus engineers say there is no single cause, but a combination of factors can trigger it​ gsmarena. Chief among these is OLED aging and stress. Over time, tiny degradations in the OLED panel or its bonding layers can cause a permanent defect. For example, OnePlus notes that India’s hot, humid climate can accelerate AMOLED wear-out, so older screens may fail faster here​ indiatoday. If moisture or oxygen creeps in at the edges of the panel, it can short out pixels. OnePlus is even adding a PVX edge-sealing layer on new displays to block moisture/oxygen, implying corrosion is a factor.

Another common theory is connector damage: a loose or damaged display flex cable can irreversibly short the screen, creating a green line​. (This can happen from a drop, pressure on the screen, or just long-term stress.) In short, it’s a physical display defect, not something like a bad software update. Many affected users report the line appearing suddenly after a routine software update or normal use​, which is likely coincidental. The bottom line: the OnePlus green line stems from a failing AMOLED panel (the “OnePlus AMOLED problem”), often due to aging, moisture, or stress on the hardware.

How It Affects Users (Especially in India)

For everyday users, the green line can be a real headache. It cuts across all content – messages, photos, videos – at all times. In India’s bright sunlight, the line is especially obvious. Imagine watching a movie on your OnePlus phone and seeing a neon green stripe slicing the screen; it’s distracting and annoying. Many middle-class Indian buyers spend ₹30,000–₹50,000 on a OnePlus device, so discovering a factory defect is distressing. In practice, affected users on forums report frustration that a flawless phone suddenly looks defective.

Worse, the green line issue previously meant a costly repair. Most manufacturers quietly ignored it, so owners had to pay out-of-pocket. As Times of India notes, customers were often “left to pay for out-of-warranty repairs or live with the defect”​timesofindia. With screen assemblies costing thousands of rupees, that was a big burden – for many, it was nearly half the phone’s original cost. (For example, a OnePlus 9R launched around ₹27,000; its AMOLED display is a premium part.) It’s no wonder users on community forums and social media have been vocal about this display issue. Some even jokingly suggested OnePlus should market it as a “feature”!

Thankfully, OnePlus is now stepping in. But before that, this problem affected users of many OnePlus models (8-series, 9-series, etc.) especially under India’s hot conditions​. If you saw green lines on your OnePlus, you’re not alone – it’s a widespread OnePlus AMOLED problem that the company has finally acknowledged.

OnePlus’s Official Response: The Green Line Worry-Free Solution

In late 2024, OnePlus launched a formal program to tackle this. The company calls it the “OnePlus Green Line Worry-Free Solution”​. This is a comprehensive three-step plan: improve the display hardware, beef up quality testing, and extend warranty coverage on the screen. OnePlus India’s CEO even boasted they were “the first brand to offer a lifetime warranty for Indian users,” showing confidence in the fix​.

Improved Displays: Going forward, all OnePlus AMOLED screens get a new PVX Enhanced Edge Bonding Layer. This extra sealing material acts like a moisture barrier, slowing down the ingress of water and oxygen that can degrade the panel​ android. In other words, it’s like a “metal shield” for your screen edges. This PVX layer is being added to all new flagship and Nord models, including the OnePlus 13 series ​oneplus.in.

Rigorous Testing: OnePlus has also dramatically upped its factory QA. Displays now undergo over 180 stress tests, simulating real-world abuse. For example, a “Double 85” test bakes the phone at 85°C and 85% humidity for extended periods​. These extreme tests are far beyond normal use and are meant to catch any weak displays before they ship.

Lifetime Screen Warranty: The headline move is the lifetime warranty on the display for green-line faults. OnePlus now promises that any of its phones with a green line will get a new screen free of charge, even after the standard warranty expires​. In fact, Android Headlines calls it “the industry’s first ‘lifetime warranty’ for display issues like the green line problem”​. GSMArena reports that if your device has this problem, “it will get a new display even if the phone itself is out of warranty”​. In other words, as long as the issue isn’t caused by physical damage, OnePlus will replace the AMOLED panel at no cost.

India Focus: OnePlus clearly views this as a bigger issue in India’s climate. Multiple sources note that the lifetime warranty is currently being offered in India (while users in the US/EU remain on a standard one-year warranty)​. OnePlus India’s guidance even explicitly mentions that this policy applies to all OnePlus models sold through authorized channels in India​ . The policy says there are no hidden charges for this replacement according to ​oneplus.in.

In short, OnePlus’s stand is: if you get a green line on a genuine OnePlus device in India, bring it in and we will replace the screen free of cost​. They’ve updated their official India website and support scripts to reflect this generous stance.

Which OnePlus Models Are Covered for Free Replacement?

Under OnePlus’s green-line policy, essentially all its AMOLED phones in India are covered. Officially, the company says the lifetime warranty applies to “all OnePlus devices sold through authorized channels.”​oneplus.in. That means any OnePlus phone (from Nord series up to flagship 12/13 series) qualifies as long as it was bought new in India.

Initially, OnePlus rolled out specific programs for older models under its Red Cable Club (RCC) scheme. Those programs covered many of the first-affected phones:

• OnePlus 8 Series & 9 Series: The OnePlus 8 Pro, 8T, 9, and 9R were explicitly listed in the free screen upgrade program last year​. These were sold for around ₹42,000 (8 Pro) to ₹28,000 (9R) at launch, so they were high-profile fixes.
• OnePlus 10 Pro: OnePlus later added 2022’s flagship 10 Pro to this list​.
• OnePlus 11 Series & 12 Series: Reports now indicate the coverage includes the newer 11, 11R, 12, and 12R models as well​. For example, Gizmochina notes “the lifetime warranty for replacements is also applicable on the OnePlus 11, 11R, 12, and 12R”​.

In practice, if you own a OnePlus phone like the 8, 9, 10, 11, 12, or any Nord model, you should be eligible. OnePlus’s India FAQ even reassures users that any device with a green line will be fixed free – there’s no need to worry about older model exclusions​. The only condition is that the phone was bought through a legitimate channel (no grey imports) and has no unrelated damage. If you’re unsure, you can always ask the service center to check if your model qualifies.

Bonus Note: Some users of very old models that reached “end of life” reportedly received vouchers for a new phone instead of a screen, since replacement parts were scarce​gizmochina.com​androidcentral.com. But under the new lifetime warranty pledge, OnePlus aims to avoid leaving anyone stranded: they promise a solution even if parts run out

What Users Can Do If They Face a Green Line

If you discover a green line on your OnePlus phone, here are the steps to take:

• Confirm the issue: First, make sure it’s not just a piece of dust or your screen protector. Remove any cover and look at your display against a plain background (like your home screen or a white page). If the green line is still there, it’s a display fault.
• Check eligibility (damage-free): Ensure your phone doesn’t have cracks or obvious liquid damage. The free replacement policy only covers internal defects. If your phone has been dropped or has watermarks, the service center might charge you (damage like that voids the warranty protection for this issue)​timesofindia.indiatimes.com.
• Visit an authorized service center ASAP: Take the phone (with its charger and a proof of purchase) to the nearest OnePlus authorized service center. If you live in a smaller city, OnePlus has centers in major cities and tie-ups with multi-brand service hubs across India.
• Explain the problem: Tell the technician you have the “green line issue” and that OnePlus offers a lifetime free replacement for it​oneplus.in. They should know about the program or check the OnePlus internal memo.
• Get the replacement: The center will run a diagnostic. Since OnePlus has committed to a free fix, they’ll replace the AMOLED panel at no cost if the phone has no unrelated damage. Officially, OnePlus states “there are no charges to be paid when replacing the display at authorized service centers”​oneplus.in. Even if your phone is out of its normal warranty period, the green line is covered under the lifetime warranty pledge​gsmarena.com​oneplus.in.
• Keep records: Make sure to note the service request number and get a receipt. Although OnePlus should replace the screen free of charge, it’s wise to keep proof of your visit just in case.

Important: Some users found this program via the OnePlus Red Cable Club (RCC) section in phone settings. If your model was one of the older ones, you could open Settings → Red Cable Club and see a “Green line free screen replacement” banner​. From there, you could claim the free panel. Now, even if you don’t see any banner, you should still qualify through regular service channels as long as your phone is from an authorized dealer​.

Conclusion

The OnePlus green line issue has been a sore point for many users, but it’s good to see OnePlus taking responsibility – especially in India. Thanks to the Green Line Worry-Free Solution, an affected OnePlus owner in India can expect a free screen replacement regardless of warranty status​. Just remember to use authorized support channels and meet the no-damage condition​. With the new lifetime display warranty, OnePlus says you can buy their phone with confidence again. If you ever spot that bright stripe on your screen, don’t panic – contact OnePlus customer care or visit a service center and rest assured: they’ve got you covered​.

Key Takeaways: The OnePlus green line issue is a hardware fault seen on AMOLED displays. In India, OnePlus will replace any affected screen for free under its lifetime warranty policy​. Models explicitly covered include the OnePlus 8/9 series (8 Pro, 8T, 9, 9R) and newer flagships (10 Pro, 11, 11R, 12, 12R)​, though officially any OnePlus phone sold here qualifies​. If your phone shows a green line, act quickly, keep it damage-free, and leverage OnePlus’s support to get a new screen—no charge. Stay cool, literally and figuratively, and keep enjoying your OnePlus device!
