Run On Device - problem


Some time ago I found out about the Watch Face Studio app, which allows you to create your own watch face.
Everything is great, I have created a dozen custom watch faces for myself and the problem arises when I want to display the face on my GW4… I’ve tried everything, debugging via BT, debugging via Wi-Fi (including cmd.exe - here the smartwatch is indicated as connected while it does not appear in the WFS app.
If there is any solution to this problem then please help and thank you in advance.


Be sure you have the latest version of WFS 1.1.19 there was a bug in 1.1.12 version where you had to restart WFS after the first time Run on Device (every time after boot up of the PC)

Select Run on Device and add your IP address one time to the search using + icon
Select Run on Device
It will show no Devices found
again click on the + and click on the IP address to the run on Device at that time your watch will ask if you want to allow debugging. click yes If you don’t OK that in a 15 or so seconds it goes away and then doesn’t ask again unless you close and restart debugging
Your watch will show in the run on devices click on it.

By the way I’ve never been able to debug via bluetooth when I ask support they give me instructions that are not applicable to my Galaxy Watch4.

here is more how to do it
Your watch and computer need to be connected to the same WiFi network. Unplug or turn off the Ethernet adaptor if you have your computer connected by Ethernet
You cannot have Firewalls or VPN enabled.

Enable developer options on your watch, and within those options, enable ADB debugging, and select debug over WiFi(it may take time to connect it took me about a minute before it shows the connection).
Allow the permissions as the watch requests them.
Go to Connections and write down the IP address your router assigns to your watch.
add that when you run on device in the + dialog…

If it doesn’t

Using File manager copy the address where you installed adb by default
(copy the address as text from file manger using right click on the address bar)
Open a command prompt
navigate to the folder address
cd C:\Users\USERNAME\AppData\Local\Programs\WatchFaceStudio\tools\window
Then type
adb connect 192.168.x.x:5555 (where 192.168.x.x is your watch’s IP address).
It may take a minute to connect or give a failure response
If you get a rejected error or something check your watch debugger settings.
Try in developer options to revoked permissions and force new acceptance. do the connect again.

select “run on device” within Watch Face Studio, your watch should show up.

If it connects but will not run on device create a new keystore in a new keystore folder

Thank you very much for your quick reply. I checked all the options you mentioned and still nothing about loading the clock face from within WFStudio…
I did try to install the watch face using cmd.exe and “adb install [name of apk]” and as strange as it may seem, the face I designed appears on the watch and works as it should. :smiley:

That is basically what Run on Device does except it does an OPR test first. Once you ran it with command prompt try to run it again with WFS and see if it works then.

No change, still the smartwatch remains unseen in the Run on Device option.

Just to get this correct.
On your watch you open Settings → Developer Options → ADB Debugging On
scroll down to Debug over WiFi it says not connected for a few seconds then is connected and the last line is your IP Address and among other things shows
in WFS
You click Run on Device.
It checks OPR
It does scan for devices
It shows No Compatible Devices
you click on the + icon
your Watches IP address is there already (if not you need to enter it) Click OK
Allow Debugging dialog pops up on your watch immediately after that Tap OK
Your device should now show in WFS click on it
Run on Device starts.

If that doesn’t work but it does allow you to sideload it manually And you have the latest version of WFS I"m stumped.
