Cache and Dalvik cache - Galaxy S I9000 Q&A, Help & Troubleshooting

Have been using JB ROM from Elitemovil for two months now and noticed that the phone is now slower than before.
Can I just delete the Cache and Dalvik cache from CWM recovery and count that all things and programs will work fine after I restart the phone?
And - BTW, can both cache's be deleted anytime without any future problems with installed programs or any other setting?
Will these cachees be automatically rebuild during boot process?

Dalvik cache is associate with the booting of the phone... deleting it will generally not affect the performance of the phone and nor will it cause any problems with the installed apps and settings...
Deleting cache may improve the performance of the apps whose cache will be cleared.. Don't think that it'll make any major difference though..
Dalvik cache is rebuilt when you power on your phone after clearing dalvik cache.. the other cache is built as you use your applications.

What the hell is wrong with you?! Every time I open a topic in this section you advise people to wipe their phones. That's not what "help" means. Looks like you're a little post farmer...

A question about wiping

OK, just a quick background:
I have a G1,
running Amon_ra's Recovery Image
CyanogenMod-4.2.13
OK, so I love Amon-Ra's recovery because it makes all the maintenance things very easy. Wiping the Dalvik Cache is a quick task.
Here's my question: When folks on here say they wipe every month of so, or wipe before each new Cyanogen update, do they mean wiping everything? SD card reformat etc? Or do they just wipe certain things?
I had never wiped before 4.2.13, and found each Cyanogen release more sluggish and crashy than the last. Then I wiped, installed 4.2.12, and it ran like a brand new phone. I loved it. But now a couple weeks has passed and my phone is slowing again. I tried wiping the Dalvik Cache but didn't see any real improvement.
So do I need a full wipe to get things back to speedy? It seems like a big pain in the ass to have to reinstall all my apps, reset notification tones, etc every time the phone gets slow. Is this the case, or is the general term "wiping" refering to a lesser operation?
Thanks for any help,
Tony
It is easy to backup the apps with the command 'pull' in adb, then use the command 'push' to push them back and the phone will install them.
I would just bite the bullet and redo your settings. I know there are programs like backup for root users that will redo the settings, but I have had problems with it and would rather reappy the settings myself.
One other option to try first: download "Cachemate" from the market. It's a paid app but so worth the buck.
The app clears all the temp caches - you would be amazed at how much memory is taken up by the caches as apps run. And the apps often don't release those caches even after reboots.

You can also do it manually by going "setings->apps->app management->select the app, then wipe cache" And sure it will take longer, but hey, for me it is one of the joys of using a phone, actually performing those tasks.
As for wiping, in ArmonRA, wipe data, wipe dalvick, wipe ext, then go to sd partion option, and repair ext, then wipe data one last time. That is the proper way to do a full wipe with ArmonRA.
As for wiping at home, I like Charmin Ultra Soft.

LOL! and for the thread, when they say rewipe, they don't mean to reformat your whole sdcard. That would be such a pain. You just gotta wipe the ext, (if you have partitions on your sd card), Cache, and data.
-EDIT-
Oh wait he already said that..

[Q]clearing dalvik cache cause apps disappeared?

I have been facing this problem for long time.
Every time I update the build of cm7, cleaning dalvik cache will lead to some apps disappear and never come back.
How can I fix this?
This is a very odd problem because the apps should not be sitting in the dalvik cache
Is it always the same apps or is it just a few random apps?? Are you using apps to sd??
Try fixing permissions. If that doesn't help, go with a full wipe and clean install...

How to clear Dalvik and Regular caches without rooting?

Hi Guys....
How can I clear Dalvik and Regular caches without rooting the Bionic?
You don't need to worry about the dalvik cache but theres an app called superbox that allows you to clear all of your app caches at once.

Thanks for your help. Problem is, that even if I do a factory reset, apps like VZ account management still remember my account info.
I have a feeling that dalvik is holding the cached info. I am still not rooted and wont be until the end of next week. I want to see if there is a way to delete dalvik without installing any other software and not rooting.

If I remember correctly, that info is stored in the /data partition, not the /cache or /dalvik partitions.

[Q] Difference between Factory Data Reset vs CWM Wipe

What's the difference between doing a Factory Data Reset and doing a wipe using CWM.
I'recently rooted my Note and now have CWM installed.
I plan on trying a few different ROMs (both newer stock ROMs and eventually custom ROMs) and read in most instances to per a wipe before upgrading.
I was wondering which wipe to use.
Also, if I install Titanium Backup, will it save everything including Contacts, Network settings, icon layouts, webpage favorites, appa and everything else?
Thanks

Cant say surely about the difference between factory rest of data and CWM wipe. But can surely say to flash any rom you need to CWM wipe all the data and cache and dalvik cache from the recovery.
And Titanium Backup is for backing up and restoring all your apps and their associated data and market links. It doesn't backup contact (should auto backup to your google account or use any contact and sms backing app from market like - https://play.google.com/store/apps/details?id=com.idea.backup.smscontacts&feature=search_result) or
layouts . Icon layouts you can save by going to the backup settings of the launcher you are using and favorites you can again backup on your sd card.

CWM recovery wipe cache, is just wiping cache files not data
while CWM recovery wipe data n Hard reset from setting - privacy - erase data(factory reset) is same
CWM function is useful when you unable to boot device normally.
Where is dalvik cache located ? Because if it's in the data or cache partition, then I don't see why I have to wipe dalvik cache after wiping data/cache...

System apps' dalvik-cache in /cache
Data apps' dalvik-cache in /data
Hence just by clearing the cache you clean the /cache space of system apps and not the dalvik cache of data apps.
So you require to do both - clean cache and clean dalvik cache.

Factory Reset will change your Android ID. Some apps with custom DRM may stop working. Factory Reset is also incompatible with some ROMs and causes some apps/files installed by CWM flashable ROMs to disappear.
I think both are same. Both format data and cache partition.
(that is why devs warned not to perform FDR on affected kernels)
With FDR you initialise the command from booted phone.
CWM Wipe is what you do from recovery mode.

[Q] Keeping system settings after flashing

I will upgrade to CyanogenMod 10.2 20131225 (maclaw's) from 20131216. I've set my system preferences and looks just as I like it and I don't want to bother re-setting everything again after the flash. How can I do that?

Just flash the rom (update), wipe dalvik & cache then reboot. You won't lose you previous settings

thanks. just to state the obvious: i don't wipe the dalvik cache, system, cache and data before installation? (pretty much* doing the same here?)
*: without re-installing the google apps, of course.

Simply wipe dalvik & cache after flash the update, that's it. Don't mess with anything more & you're good to go
