I just came across the folder
dalvik-cache having size of about 750MB.
I searched for dalvik cache on google, and came to know that it is builded during boot up, and wiping this will make the next boot slower.
So whether wiping dalvik cache is not at all useful?
My doubt is that whether Dalvik cache has some files related to only the uninstalled apps?
If so, how we can find that files?
Or Dalvik cache components get deleted when we uninstall an app?
EDIT: My phone is rooted.
