Wyze Air Purifier Fan Speed Adjustment Through App Not Working on 3.21.1(962) Android

Since the 3.21.x Android update I noticed I could not adjust the fan speed via the Android App anymore (by pressing the Manual button).

I thought my machine was broken, but the physical button on top of the purifier allows fan speed changes fine. I needed another air purifier, so I ordered one with the Wildfire filter, and it does the same thing. When you tap the “MANUAL” button in the app you are presented with a screen that has UNLOCK LOCK, then MIN MID MAX TURBO. You can change it to any of those speeds, but the machine never recognizes it. The SAVE button is gone now in 3.21.x. There is a Reset button, but it seems to only work with the timer function. Firmware is 1.0.18.0 on both (the new one came with the current firmware), the Plugin Version is 3.21.01. It does not work on LIGHT theme or Dark Theme. It does the same accessing via the Favorites or Devices screen. Thanks for the help!

Mine is working fine and the save button is there. However, it is a bit cut off. On your Android device, what resolution are you using? It may be a bug with not taken font size or resolution into account when the screen shows those options.

Note: I am testing the Beta version of the app which is 3.22.0 (b965). But I was able to control the fan on 3.21 as well.

Have you called in and opened a ticket? You should also provide a log for Wyze to review.

Can you attach a screen shot?

It does it on a Pixel 6a and Pixel 8. Both fully updated to Android 17 (well not the September 2026 updates yet).

I am using the Pixel 9 Pro. This is what I see, notice how the save button is cut off some

Edit

Just checked the Display Size and Font / Text sizing. No change in what I see.

Can you all check on your devices, assuming you have and use a Wyze AP

Note: On my Samsung S26+, the display looks fine. So this might only be related to the Pixels.

I just went into Settings, Display & Touch, Display Size & Text, and made it very small on Font and display and I still don’t see SAVE below the custom button. Tried to do bigger fonts and no go either.

I tried resetting the fonts/display size to default too, I also disabled developer options just in case that had anything to do with it.

That was my experience as well. I have forwarded this thread to Wyze to see if they can look into it. May only be a Pixel issue as I do see the buttons on my Samsung

I don’t have that product, so I can’t really help with this.

The workaround seems to be to tap the extreme lower right corner of the screen after selecting fan speed, and it will save the fan speed, and return you to the main Air Purifier screen.

Wow, I would have expected that to adjust the timer. But glad you found something

That was the smart person in our family that figured out the workaround, not me.

:slight_smile:

One thing I did find during all this (that made it worth the effort) was under Android Dark Theme there is now a selection for “Standard” vs “Expanded” dark theme. The expanded option darkens certain other android apps that do NOT have their own dark theme.

Going to Gesture Navigation from 3 Button Navigation mode makes my screen look exactly like yours! I just cannot get used to Gesture Navigation though.

Sorry for the delay. Mine looks EXACTLY like yours on my Pixel 10 Pro XL and my Pixel Tablet (slightly cut off at the very bottom).
Looks like the app is pushing things to the bottom of the screen, but my pixels have a tiny footer at the bottom for quick navigation or long-pressing to circle to search or whatever. The Wyze app should probably take that into account.

Thanks. Wyze confirmed it for me as well. They are looking into it.

Can confirm problem exists with Samsung S23 Ultra. This surfaced as a result of the last app update.

Do you use 3-button navigation or Gesture Navigation?

When I switch to Gesture Navigation I can see the SAVE button.

This may be considered good news because this means someone is looking into maybe fixing the problems with the Air Purifier.

v3.21.xxx has broken many screens

  • The Air Purifier Screen mentioned here.
  • Thermostat screen has a much larger font.
  • Some cameras have landscape mode view clipped at the top and bottom.

It appears the App has been compiled for Android 16 and above which now forces “edge-to-edge” screens and the developers have not adjusted the screens to account for this!

Just happened upon this thread.

The Air Purifier should be fixed in the next app update. The Thermostat should be fixed very soon.
