Hello there. Just gotten my Nexus 7c about 3 weeks ago. Overall it was a very good device with an affordable price I get the latest android version and alot of good stuffs. 3 weeks of usage I've noticed that the cache files for my apps are eating some space in my storage. So my questions are : - Do we need to clear cache files for apps regularly? Like clear it once every 3 days or once a week? - I've read somewhere that android needs more RAM in order for apps to run faster and load up faster the next time we use them. And more RAMS would be better as long as it doesn't get too low. And using task killers/managers are not so good for android unless we're using it to stop some buggy apps. So is the cache files the same situation as the RAM? - Is a battery saver app needed for new android phones or tablets? Like the Juice Defender app? Am a lil worried that the battery saver app might dmg the new battery since its still new and can last like 2 days with 3g + surfing the web + games. Any advice would greatly be appreciated. Thanks in advance.
