Green line during One UI update? Here's video proof of it happening on a Galaxy S21 FE
TL;DR A user documented the appearance of the dreaded 'green line' issue on their Galaxy S21 FE's AMOLED display during a One UI 6.1 software update.
Despite thousands of affected users across multiple device lines, Samsung does not have a transparent policy for addressing these known green-line screen defects.
For years, green line issues have plagued AMOLED displays across flagship and mid-range phones. Some OEMs like OnePlus offer a lifetime display warranty against green line issues in certain markets, but most other OEMs have left the consumer to fend for themselves. The problem is that the green line appears on the device without the user's fault, usually around an update. While we have seen many, many, many photos of the green line issue so far, we now have a video recording of the green line appearing on a device while an update is being applied.
Reddit user kingshukroy01 (spotted by Sammobile) stuck to One UI 6 on their Samsung Galaxy S21 FE for fear of getting a green line when they apply the impending One UI 6.1 update. Note that this One UI 6.1 update rolled out in May 2024 for the S21 FE, so the user has been avoiding the update for over a year already, despite One UI's update installation reminders every day! Fed up with the reminders, the user finally installed the One UI 6.1 update. Guess what happened next?
Before update
After update
Since the user feared the worst, they recorded a video of the device update process. Unfortunately, their worst fear materialized, and the phone gradually got a green line on the display during the update process.
Unfortunately for the user, Samsung does not have a publicly informed, on-the-record policy for handling green line issues. The user approached Samsung's service center, where they were told they needed to produce a purchase invoice for their two-and-a-half-year-old device, which they don't have. So it is unclear if the user will get any relief for an issue recorded to come with a software update through no fault of their own.
It's a ridiculous situation all around, one that makes you lose faith in AMOLED displays as a whole, and certainly doesn't inspire confidence in Samsung for your next smartphone purchase.
We've contacted Samsung India for more information on the company's policy for dealing with green line issues and what steps it has taken to prevent the problem from cropping up on newer smartphones. We'll keep you updated if and when we learn more.

Apple finally got good news about the iPhone this week
The iPhone 16 is on top of the world. The base model iPhone 16 was the best-selling smartphone in the world in the first quarter of 2025, according to a Wednesday research note from Counterpoint. It was the first time in two years that a base model iPhone was in the top spot. Apple continued its streak of dominating the top five smartphones globally. The iPhone 16, followed by the Pro models and iPhone 15, are at the top of the list, with Samsung's Galaxy A16 5G in fifth place. In China — a key region with increasing competition — iPhone 16 Pro models have a steeper challenge due to government subsidies offering discounts on devices under 6,000 yuan, about $833, making the Pro ineligible for a markdown. However, the Pros pulled through to make up nearly half of Apple's iPhone sales for the third quarter straight. All of this is good news for Apple, according to Jacob Bourne, a tech analyst at Business Insider's sister company, EMARKETER. "This is definitely a crucially timed win for Apple. This demonstrates strength in their flagship product lineup despite economic headwinds and ongoing uncertainties," Bourne said. However, Morningstar analyst William Kerwin isn't sure the tech giant should count it as a win. "The iPhone is routinely the best selling smartphone—and the base variant overtaking the Pro this year shows the narrowed gap between the two models this year due to both needing enough chip content to run Apple Intelligence," Kerwin told BI. Apple is in competition with itself and its past iPhone sales, which Kerwin said have been "lackluster this year and over the past two years." Topping the global charts doesn't indicate that Apple is sitting pretty again, Kerwin said. iPhone revenue missed targets during its fiscal first quarter, coming in at $69.14 billion versus the $71.04 billion estimate. The iPhone 16e, however, was an "interesting" piece of Counterpoint's data, Kerwin said. The budget-friendly iPhone, which starts at $599, ranked sixth in the top 10 best-selling smartphones in March — its first full month on shelves. It's expected to outperform its predecessor, the iPhone SE, in its first year. "Overall, we've seen a narrowing of the delta between budget, base, and pro models this year," Kerwin said. Apple has had a tough 2025. CEO Tim Cook seems to remain in limbo with the Trump Administration as President Donald Trump routinely updates his stance on tariffs. On May 23, President Donald Trump said he would implement a 25% tariff on Apple over plans for US iPhone production to be moved from China to India, Trump said in a Truth Social post. "We believe the concept of Apple producing iPhones in the US is a fairy tale that is not feasible," WedBush Securities' Dan Ives wrote in a note on May 23. Almost one year after it was first announced, Apple Intelligence is also a growing concern for Apple and its investors. The AI tools advertised aren't driving sales the way analysts predicted in 2024. "The AI-enabled iPhone 16 still has not revitalized this growth, much less driven a supercycle," Kerwin said.

Does the Samsung Galaxy A13 have wireless charging?
Ryan Haines / Android Authority The Samsung Galaxy A13 is a fine choice if you want a functional and cheap Android phone, but does it have wireless charging? After all, wireless charging is convenient, and plenty of other phones have it these days. Find out below if this phone has wireless charging and what you can do about it. Does the Samsung Galaxy A13 have wireless charging? No, the Samsung Galaxy A13 does not have wireless charging. If you drop it on a wireless charging pad, nothing will happen. This is to be expected since phones in this price range usually don't have wireless charging capabilities. You'll have to spend around $500 or more to get a phone with wireless charging. However, even in the $500 price range, a lot of devices don't have this feature. However, the Galaxy A13 does have fast charging, so at least you will not be tied to a cable for hours. A half-hour charge will net you around 20% battery, while two hours tops up the entire thing. Unfortunately, the trend of not including power adapters in the box has hit Samsung, too, so you will have to supply your own. How to add wireless charging to a Samsung Galaxy A13 You can add wireless charging to a Samsung Galaxy A13, but you will need an adapter. These plug into the USB-C port on the bottom of the phone and let you use wireless charging pads with your phone. These adapters are usually pretty thin so that they can slide between your phone and a case. That also means they are up and out of the way and stick to the back of your phone. We have not tested these and cannot vouch for them, but these and similar options should bring wireless charging to your Galaxy A13. Remember, you will require a wireless charging pad, too. The Nillkin Qi receiver To add wireless charging to your Galaxy A13, attach this receiver to the USB-C port and stick the flat, broad end onto the back of your phone. You can then insert your phone into a case if you wish. Just ensure it's made of plastic so it does not interfere with wireless charging. It works with fast charging, too. Note that you can buy it in a short version and a long version. The short version measures 9.3 cm, while the long one is 10.4 cm. If you're unsure whether the long version will hit your camera lens or fingerprint scanner, opt for the short version. Options that have a Lightning or micro USB plug also exist, but these won't work with the Galaxy A13. Other options to consider There are plenty of other great options available on Amazon. They all work similarly to the Nillkin Qi receiver and are similarly priced. Check a few of them out via the links below.
