It's like the title says, AVG cleaner won't clear the cache! Whenever I click on clear cache, it goes to the screen where it says "clearing cache" but then abruptly stops, goes to landscape orientation, crashes and then takes me back to ther AVG cleaner app. This also happened on my previous phone, seems to work just fine on my tablet though. Is this issue heard of?
