Is there a difference when I clean cache through an app say Clean Master VS when i clean cache using a custom recovery? Does cleaning cache from an app do anything?Or is it obsolete?

[Q] "Wipe cache partition" in recovery mode seems useless? What is it for exactly??
Hi. I'm using Samsung Galaxy Ace, Android 2.3.6, rooted.
I had 2 apps with cache data:
1. the system app "Internet" = 444KB
2. a user app called "RedLaser" (for reading QR codes) = 45KB
I turned off phone, went into recovery, then "wipe cache partition", then reboot.
It did nothing! The two apps still had cache, and I just deleted them manually in Settings -> Manage Applications.
So what does the "wipe cache partition" do anyway?
Also, if a phone is unrooted, is there a way to clean the dalvik cache?
Thanks all!
Its for wiping the cache of your phone application..some times if you not do this then you r apps will crash in the new rom..so its optional thing.but some times it needed...understood??
shyamjptpm, did you even read the details of my post? The cache of those two apps were not deleted through "wipe cache partition" in recovery mode. So I was wondering what it does, exactly, since it DOES NOT wipe the apps' cache.
The cache is an app cache, but not a cache of application data. You wipe that through application management (or manually with a file explorer or shell).
Think of it as an Android cache that it uses for apps and components.
Hey Archer, an app cache? Like the dalvik cache? The dalvik is for starting apps faster, correct? So is "Dalvik cache" same as the cache referred to in "wipe cache partition"?

No it's not apps - I explained that badly. It's regularly accessed data and app components, but not app-specific data. The Dalvik cache is the application cache - they are two different things.
Additionally depending on which recovery you are using, wiping the cache might not properly work all the time, that is why you read so many posts saying wipe +3; meaning to run the wipe cache (and dalvik) at least 3 times. I know I had issues with one specific recovery and switched to another because of it...

Hey, is it possible to wipe cache partition without getting into recovery mode?
And wiping the cache partition and dalvik cache will delete my game progress??
Please clarify this for me bro...
when doing a full wipe what's the difference in doing a factory reset and wipe cache + dalvik from just doing a format all the partitions( except the sd card)? And also what the difference if you were to just wipe cache and wipe dalvik cache rather than just taping on the wipe cache + dalvik by itself?Just wondering so for all the topics.

Factory reset wipes, data, dalvik, cache and boot.

No difference, you just do one but not the other when you wipe just Dalvik for instance.
I gotcha ya!!!

Hi,
Today I successfully rooted my galaxy Tab 2 7 P3100. What I am not sure is when and why we need the
Wipe Data/Factory Reset
Wipe Cache Partition
Wipe Dalvik Cache
I want to understand because I plan to try couple of other ROMs. Should I follow the above procedure every time I flash a ROM or is there a better way where avoiding any of the above is an option.
Regards.
to minimize the conflict that would occur if you use a different rom base
try it without wiping, usually meet force close dialog after booting
all i know is that wiping cache will clear data related to applications, so if you have an app force closing all the time it is sometimes handy to wipe that app's cache from the settings or wiping the entire cache from recovery.
wiping data/factory reset however will remove any app you have installed and all your personal files that you've put on the device.
Basic breakdown,
If going from one base ROM to another base ROM like stock to CM, CM to AOKP, stock to AOKP or anything like that you will need to do ALL 3 wipes.
If going from like a CM10 nightly to a newer nightly you can usually just wipe CACHE and Dalvick
If you flash addons you will usually need to wipe cache and Dalvick
BASICALLY just do what the INSTRUCTIONS for the ROM your flashing SAYS to do.

First of all a BIG THANK YOU.
Now One more doubt there is this ROM which I want to flash and it says to wipe dalvik cache before and after flasing the ROM. Please confirm only Factory reset will clear the existing ROM and wiping Cache and Dalvik cache wont affect the existing ROM(or internal SD Data)
Thanks again.

OK well flashing any ROM will replace your current ROM, NONE of your files (music, pictures or things like that) are touched by ANY of these wipes, Factory reset wipes out installed apps, wiping cache and dalvik after flashing or hell wipe data/factory reset won't touch the apps "built-in" to the ROM.
remember the ROM is your operating system and your files (music, pictures, and other stuff) are in the internal SD which is a separate partition from the ROOT system folder where the OS files are.
Wipe Data/Factory Reset - wipes all APPS and Google account information and resets all devices settings to default
as for the other 2 read through the answer here http://android.stackexchange.com/questions/25859/why-do-i-need-to-wipe-dalvik-cache it explains what the other wipes are about.
Hope that covers it, basically jumping from one ROM to another the most you can lose is your basic settings and your APPS (which can be redownloaded, if you didn't use an app to back them up first, but you would lose any progress in your games if you don't back them up).
Should I do a complete data wipe for a new kernel or just wiping cache & dalvik cache enough?
Cache and dalvik is all

"Wipe dalvik cache" is a legacy title (kind of).. It will wipe your current virtual machine cache.. You can check it by wiping and rebooting (if android optimizes apps on next boot, dalvik/ART cache was wiped)

There may be some boost after 2nd boot because of cleaning cache of uninstalled apps and caches that got bigger and bigger over time
