Text (SMS) messages are not deleted by CCleaner even though they are selected to be deleted by the cleaning operation.
Hi longknife, and welcome to the forum.
How are you selecting SMS messages to be deleted? I can't find anywhere within CCleaners settings to do that.
Unless CCleaner displays different settings for Android 4.2.2. than it does for 5.1 (my phone), which would surprise me but probably not impossible.
Or, you have the Pro version which I don't, and you have extra options within the settings dialogue?
Other than that, the only place I can find SMS messages is in CCleaners "Manual cleaning apps" section which appears after analysing. If that is the case, when selecting one of those items CCleaner simply takes you to that item to manually clean cache, data, or in this case SMS messages. You have to do it yourself and then back button to CCleaner again.
Let me know exactly what you have and we'll take it from there.
