Nintendo Switch 2 System Update 20.4.0 Is Now Live, Here Are The Full Patch Notes

Me to Stability:

(We Nintendo fans are super creative and fresh with our jokes, as you can see)

Something something stability joke.

I got nothin', sorry

So stable and I can mount on my Switch like a horse.
Neiiigh....!!! 🐴

Thanks to this update, my Switch 2 survived an earthquake.

my switch 2 is more stable then its new kickstand

Switch 2 Firmware 20.4.0:
– General system improvements to stabilize… something.

This was the real reason for the release of the Switch 2. The Switch 1 was too stable. They needed a new console to start their stabilizing over.

I hope there is any added "Southeast Asia Region" for Eshop and Online. Also update important fix patch for Battery Indicator.

I wish Nintendo would send a stability update to my girlfriend's brain.

Ah yes, I thought the atmosphere around my Switch was distorting again. All is now right in the world.

The endless void under my house was getting too big again. My Switch's new burst of stability will fix it. Thanks, Nintendo!

Now, I don't know if my Switch 1 suffered an issue or if my internet connection started to hate me, but since the weekend I haven't been able to play online (therefore I couldn't partake in the Sonic Racing: CrossWorlds online mode) or browse the eShop without getting an error.

I even tried using the system on handheld mode in the room where the modem is and I still got errors. Has anyone else had this issue recently?

Glorious stability!

And they say this thing costs too much when it can save you thousands of dollars from having to get a therapist?!

Will the added stability prevent the dock from falling forwards?

I'm able to play stable on my switch over a table

Improved stability for when Samus is landing in Metroid Prime 4

Its way more stable now in my hands.

Controller handling codes?

It would be funny if just once, as a treat, it would read: "Caught one of those dirty hackers, watching their ass OUT!"

Yes the only thing stable about me is my Switch update...

My Switch 2 got knocked over the other day so I'm really glad Nintendo has addressed this

I'm beginning to wonder whether Nintendo is in on all this stability malarky and releases the updates with the heading 'stability' just for kicks, so I asked them.
"Hay, Denny.
In response to your question. Neigh, here at Nintendo we don't horse around about such things. We don't want our users to be chomping at the bit with our systems and we do our best to ensure a smooth ride."

@CaleBoi25 New update makes the Switch2 so stable not even Ubisoft games can crash it....

@DennyCrane
Can't decide if this is for real or not 😁

@breach187 OMG this makes so much sense when the switch 2 has no library 🤣

I’m saddened to hear there’s still no fix for Nier Automata

@Cakefish yeah we need update for nier automata. always crash when fight crowd enemy .

Hope this fixes more backwards compatibility issues like the last system update did. Though if it does, Nintendo should really be more forthcoming with this information instead of just leaving people to figure out what, if anything, was fixed.

If only the world geopolitical situation was as stable as my Nintendo Switch 2, the world would be a much better place.

@SpaceboyScreams idk if Nintendo would send out an update for a brain they didn't make but I know a guy who might be able to get Doom to run on it

There's no news on the titles having compatibility issues. Nintendo has slowed down significantly in this regard. Not to mention youtube.

My hands are now stable to hold the switch for a prolonged play.

you know I was holding off I getting the switch 2 but this has change my mind.

@molkom oh it's absolutely real, I made it myself

Nintendo direct incoming. Might even be this week

The "lol stability" joke is the cockroach of comedy.

I come for the update, but I stay for the bility.

…How stable can Switch get?

I suppose they're too busy faffing about to fix the battery drain in sleep mode.

So stable, I'm gonna start keeping horses in it.

It's almost close to a decade now they still had not found a way to add custom themes to Switch. What a way to be behind the time Nintendo.

So stable that the launch S1 can now use its kickstand properly.

@Serpenterror or a web browser, or Netflix, or "insert other item that the Wii U had".

Just please, please fix NiER Automata in one of these updates, please.

Mmm. My ethernet port in switch 2 seems to have stopped after the system update. Anybody else with the same problem?

Can we get anymore stable?!?!

It's so snappy!

@Matt_Barber I have that patch. It's a box set of Get Smart DVDs.

I tested the update thoroughly.

System didn't tip over. So probably is more stable than before.

I would bet Most of these updates are more about sharing data with Nintendo so they get detail info from active sytems, purchases, physical games, and game progress! And most importantly updating the annoying game virtual cards!!!!!! These updates are the most annoying thing ever, popping up all the time to force everyone to update and you can’t turn it off!

@dskatter thats up to SE to solve

@arkanjo29 And yet other games are getting fixed purely by Nintendo system updates.

It’s almost like it could be Squeenix’s issue OR it could be Nintendo’s. Or both.

Have they fixed captive wifi support ("This feature is not available" error)?

@dskatter the only games that i've seen being fixed by nintendo are nintendo games, other games get a patch by the dev to solve it

@arkanjo29 Then you’ve missed articles here and online reports stating game issues have been fixed with system updates. Articles on this very site have shown issues fixed with system updates and not game patches.

And now you know!

@dskatter and now i know
