How can I clear the cache from my windows 8 smartphone? The brand name of the phone is Huawei it is using data like crazy and I would like to be able to clear the cache so it will not start slowing down. I've only had the phone for 2 weeks and already it is showing more than 1.0 G used! Do I have to get an app to clean my phone daily? If so, please tell me which one and if there is an app that is free please. Thank you very much for your time. Have a great day and be safe especially with what day it is. Respectfully, Stephanie Robinson (new user of a smartphone) :)
