Since the launch of the Switch, some users are victims of Joy-Con’s untimely disconnections. Nintendo first mentioned interference, but nowadays, the Japanese speech changes: there are many worries about the first series.
We recommend not to use the Joy-Con near an aquarium or next to a microwave oven. This was one of the many tips Nintendo gave to explain the loss of synchronization or disconnection of the Joy-Con left a few weeks ago. Problems only occurred when the small controller was used wirelessly with the console / tablet.
Of course, Nintendo maintained that no technical concerns had been found by its services, but that it was always possible for users to send the Joy-Con a bit harder, after customer service had Agreed that there was a concern.
This is what Sean Hollister, journalists at the American site CNET did. After a phone call to the American after-sales service and then a return of his Joy-Con to Nintendo, our American colleague received his small handset repaired, five days after she left her home.
Curious to see what had changed or been repaired, he undertook to disassemble the device and discovered a simple piece of foam affixed to the printed circuit between the plastic shell and a piece of metal protecting the components charged with interpreting The movements of the joystick as well as the Bluetooth antenna which is responsible for transmitting them to the console.
The new Joy-Con would have a different motherboard
According to the journalist and some specialists of the site TechRepublic (affiliated to CNET) it would be a foam whose chemical composition (copper and / or nickel) would limit interference from external sources. To make sure, Mr. Hollister removed the small piece of foam and the malfunctions resumed.
To complete his experiment, the journalist ordered a new Joy-Con left and disassembled it. No trace of foam but the motherboard of the small controller has different references. According to him, Nintendo would have found the origin of the problem, would have corrected it and the Joy-Con henceforth sold would no longer be potential victims of technical worries.
He did not think so well. After the article published on CNET, Nintento USA has split a press release, published in its entirety by Ars Technica.
Firstly, according to Nintendo, there are no design problems with the Joy-Con, and the possible interference problems found on a “minority of controllers” are due to a “slight difference Design on certain production lines “. A difference quickly identified and rectified according to the firm which adds that it has “succeeded in determining that a simple repair can be done on the controllers today affected in order to improve the connectivity”. No doubt the famous piece of foam reducing interference.
Nintendo then re-assumes that other concerns may cause interference and will contact technical support if necessary. A repair that Nintendo takes care of, with a return of the controller in less than a week.
