How to clear the cache on your Samsung Galaxy watch

Samsung Galaxy Watch 4 wipe cache partition

If you find that your Samsung Galaxy Watch runs too slow, is laggy, or you can’t install or update apps due to memory issues, clearing your watch’s cache might just do the trick!

The cache on your watch contains temporary files from apps and your operating system that are non-essential to the watch’s function. So deleting them often helps your watch perform at its best by removing old cache files that your watch no longer needs (and might just be causing problems.)

Although Samsung offers ways to clear your watch’s cache, it’s not a featured function. Since you have to dig a little to find the option to clear your watch’s cache, this article shows you how step-by-step.

So let’s get to it!
