The Nintendo Switch caught up with its defective controllers

Consumers filed a lawsuit against the Japanese manufacturer because of the "Joy-Con Drift", ghost movements that can render the console unusable.

This is a concern faced by many of the owners of Switch, the Nintendo console released in 2017. A little glitch of nothing at all, but that changes everything: sometimes the character or cursor on the screen is a few steps aside. All alone, without the player asking him anything. Left to cause unexpected failures, even, in the most extreme cases, to make the use of the console impossible.

At issue: the "Joy-Con Drift", nickname of a bug that suffer the handles of some Switch. This one sometimes considers that the joysticks are pushed in a direction, even if they are actually in neutral position, thus giving to see annoying unexpected movements on the screen.

Already identified on Switch, the problem now Switch Lite, the compact model marketed by Nintendo since September 20, as noted by some users, video unsolicited camera movements to support.

This recurring defect prompted US firm Chimicles Schwartz Kriner & Donaldson-Smith to mount a class action in July against the Japanese company. The 100-page complaint, co-signed by nineteen US consumers in 16 states, has been spreading since September 20 to Switch Lite. She squeezes the Japanese manufacturer:

"Nintendo has been promoting and selling Switch, Joy-Con, and Switch Lite products with knowledge of their failures, stick issues, and unreliability . (...) Nintendo downplayed the scale and severity of the Switch, Joy-Con and Switch Lite problems, refusing to admit that their controllers were defective (while giving up the limitations in time of the guarantee for customers complaining). "

One of the users mentioned gets upset that the fault resurfaces almost immediately the console unpacked. "I finished The Legend of Zelda: Link's Awakening over the weekend on my Switch Lite, I played just twenty hours in total, and she's already starting to show signs of Joy-Con Drift [drifting Joy-Con] . Why does this happen earlier than on older models? "

Nintendo is currently low profile on the problems faced by the Switch Lite. In July, after the filing of the class action in the United States, the century-old Japanese firm invited affected consumers to get closer to its after-sales service, while acknowledging half-heartedly the problem in a statement to The Verge  :

"At Nintendo, we pride ourselves on creating quality products and continually improving them. We are aware of recent malfunction reports from some Joy-Con controllers. "

At the same time, the US site Vice reported that Nintendo has, in parallel, sent the message to its technical teams to no longer charge for repair of defective Joy-Con. What about the Switch Lite? The manufacturer did not respond to the solicitations of the World .

A very common problem

There is no precise figure of the extent of the problem. In a survey conducted by users of the ResetEra forum, 56% of Internet users said they had already been victims of a phantom movement problem of their Switch controller, all models combined - on a sample of 600 Internet users, probably attracted by the subject of the survey. As another indication of the recurrence of the problem, on YouTube , the most popular Joy-Con video repair tutorials have been seen more than 700,000 times.

"It does not stop , " said Yoann, manager of the repair site Next-Gen Industry, which sees about fifty defective controllers per month.

"We sometimes have to change them several times for the same client; Partner shops send us dozens to repair ... it's really the big disease of the Switch, with the connector charge wayward. In my opinion, there are 25% of users who are affected. "

On the side of La Clinique de la console, an independent repair shop in Lyon, we nuance the problem: "We see pass sticks that no longer work, but it is not the most common," says a technician. The console that is most often reported to them is the PlayStation 4, "for problems with power or play the game". Pixels, which has almost daily use of the Nintendo console, has already found this fault on five of its ten switches, all standard joysticks.

"Our two pairs have become unusable"

In everyday life, these problems ruin the pleasure of playing, as evidenced by the 163 stories published on Facebook by Pixel readers . "Impossible to do a diagonal-front-right game," regrets Jean-Raphael. "Even without touching the console, the character moves to fall platforms , " complains Antoine.

"Not serious" on a Pokémon game , relativized Claire, but "more problematic on a Zelda or a Super Smash Bros  " . Leon, he speaks of a console that abandons "almost once a second . " Marine does the accounts. She has "two home switches" and "the two pairs of Joy-Con left of each console have made us so that they have become unusable. We had to buy pros for more than 50 euros each .

Others have made it through the guarantee, but, for Richard, "the only solution was to buy a pair of Joy-Con: the two-year warranty requires to find cash receipts and receipts of 'purchase, often misplaced after several years' . Others finally opt for the "do it yourself" , like Jean-Baptiste, released by his four Joy-Con ( "especially the left" ), or Hicham, who released the screwdriver and replaced his own joystick, because "Nintendo did not want to fix it" . Sometimes a little WD-40 oil is enough.

A contact patch causing the problem

Where does this fault come from? "A flexible card on which there is a small black plate called a coal, and has a tendency to wear out , details Yoann, manager and technician of Next-Gen Industry . With the wear, the character starts to go in all directions. "This is often due to overuse of the console. These problems are also found in other manufacturers. It's a wearing room , " corroborates the side of The Clinic console.

The problem is all the more surprising since analog sticks are not new technology: they have been used since the 1990s. "On Wii U [the previous Nintendo console] , there were no such problems . It's a question of whether they did not purposely facilitate wear and tear to sell more, " said the Next-Gen Industry repairman, noting that parts from independent suppliers are stronger than original.

The Switch Lite has no reason to be spared, says Yoann. "We disassembled the console when it came out to make a tutorial, and it's almost the same stick, they are interchangeable. Since the platinum that manages the contacts is the same, we should have the same problems! " Fortunately, you only have ten minutes to repair. And apart from not playing too much with his console, or favor the so-called "pro" controllers , which do not know this concern, there is hardly any way to protect themselves. "There is nothing to do, it's really the default of the Switch," laments Yoann.
