From yesterday, the App Clean Master on my D5 crashes every time I try

From yesterday, the App Clean Master on my D5 crashes every time I try to clear the watch (first option at the left that shows in red 110Mb).

I deleted the app and re-installed it from Google play, but it crashes every time.

Now I have installed Clear Master and CCleaner. Can you tell me which one is the best, please? Any idea what’s happened with Clean Master?

Finally, is CM Security - an app suggested by Clean Master I also installed when Clean Master used to work - is also needed?

Please let me know.
Thank you in advance.

I personally use AVG Cleaner FREE on my D5-- It does a better job of cleaning the cache than CM’s Clean Master… PLUS, it functions nicely within the D5’s round environment!

(Oh, and don’t worry about it crashing when restarting the D5- That’s the only time it will crash while the D5 is on.)

Thank you Dennis! I will try it.
