WEAR OS UPDATE 3.2 - Issues with the Galaxy Watch4

FAQ - Cronosurf on Android / Wear OS

How do I get Cronosurf Wave installed on my Wear OS watch?

The two easiest ways to achieve this are: or

I purchased the PRO version and installed on my phone, but when trying to install the app on my watch or another device, the Play Store wants to charge again. Why?

We receive this question frequently. So far, the issue has always resolved on its own after a few hours or next day. In this case, you will be able to install with no charge. Or, if you were already charged twice, Google will refund your second purchase automatically within a few days. This seems to be a common glitch on Google servers, and it is outside of our control. If there is still an issue, we suggest contacting Google support directly.

What smartwatch is best suited for Cronosurf Wave?

We get this question a lot. While it is not easy to give a clear recommendation with all the different devices out there, we have made a summary of the characteristics to look for and a small selection of currently available watches. Please visit our Recommended smartwatches for Cronosurf Wave section.

Why is there no widget for the homescreen?

The graphical performance of Android widgets is limited and does not support graphical acceleration. Moreover, widgets under Android are not meant to be refreshed more than once every 15 minutes. With some technical tricks it is possible to refresh once per minute, which would lead to a poor experience for a watch like Cronosurf. Therefore, in order to bring Cronosurf to the homescreen, we decided to implement it as a Live Wallpaper, which offers a much better user experience. As a bonus, it appears behind the lock screen (except on some proprietary lock screens).

When setting the background image (PRO version), the app crashes.

This can be caused by the image loader. When you click on "Select image" on the Cronosurf LWP settings, you get several options to select an image. This are usually the default loader called "Images" and your installed viewers. Some of the viewers can lead to a crash. Just try a different one or use the default loader.

Why is the Live Wallpaper option grayed out?

It is grayed out because the Cronosurf Live Wallpaper is not running. Please activate it first. The standard Android procedure is to long press on an empty area on the home screen and select "Live wallpapers" from the appearing menu. This will show a list of the available Live Wallpapers. Select Cronosurf to activate it. Please note that some Android devices require a different procedure for this.

Wear OS - The Wear watch is connected to my phone and Cronosurf is the active watchface, but the settings from the Cronosurf app don't get synced to the watch.

This can happen under some circumstances. It seems a transient problem and often times it resolves on its own. Otherwise, rebooting the watch may help.

On Wear OS 3+ devices, the sync seems to work only when the screen of the watch is fully active (not ambient mode).

Wear OS - After rebooting the mobile, the watchface on the watch disappears and I have to reinstall the app. What is going on?

This is a known bug on older devices. It happens when the app on the phone is installed on the SD-card. Just move the app back to the internal storage.

Wear OS - Why is the Screen-On timer not the same as for the smartphone/tablet?

While you can set the Screen-On timer to 5, 15 and 30 minutes on Android handhelds, the timer times on Wear OS are 1, 5 and 15 minutes. The main reason for this is that saving battery on smartwatches is more critical than on handhelds. Besides, Wear OS devices offer the always-on feature. When activated, the watch will enter the dim mode, during which Cronosurf keeps most of its appealing design and readability.
