>>863983- Don't install any of the stupid "cleaner" or "battery saver" apps. They do jack shit.
- Avoid apps with built on ads like the plague. A lot of shady apps will spam your notifications and such. Just don't install any garbage.
- If you can and don't mint voiding warranty, root, install AdAway to remove ads for everything, remove unneeded system apps with a root app remover.
- Use common sense.
