Hello ppl im new here. i had a quick question in regards to a droid cache issue. i heard that after about a year a droid phone will substantially slow down because there are certain Caches you can not clear (one being the phone cache) and they end up building up and up. is this true? i was considering buying a droid for the first time and im a pretty heavy phone user and dont want to see a kink in its performance after 1 year Thanks in advance.
