Video: Sprint Hero Frustrations

First, I have the Hero and have very few issues. If you are using task killers, stop. Those can cause that very thing. Android is very good at controlling resources. The Hero easily beats most android phones except maybe the nexus one. Also, try using commantalb off the market. It allows you to see any applications that are fully running in the background an allows you to quit them or switch to them. I would do a factory reset, restart one to two times a day which is recommended for most dumb phones even, don't install task killers and use commantalb to close programs like browser, people, and phone after using them. Also, either hit quit to exit an app or use the back button and not home. This will keep apps from running in the background. If you still have trouble, root and run app optimizer. It does little to change the actual rom of the phone, but helps speed things up. Or you could use fresh, but that will change more on your phone. Android is extremely fast, you just have to learn to use it. Also, 2.1 will fix a lot of these issues, so just be patient.
