I have the 8 GB model and over the past couple months it has really started to slow down. Everything from opening apps to changing the screen orientation to unlocking the device was really slow. It was nothing like the buttery smoothness I enjoyed when I first received the device. I recently fixed my lag by clearing the cache using a program called Clean Master. The steps I took are as follows:
1) Download and Install Clean Master from the market
2) When you open the app, there will be 4 choices. Select History
3) Give the app some time to calculate all the cache being used. When it finishes, make sure System Cache is checked and then click the clean button on the bottom.
That's it. After I did that I noticed a dramatic improvement in the tablet's responsiveness. I know that you can also clear your cache out in Settings > Storage > Cached Data. That may or may not do the same thing, but for me I used Clean Master and it worked.
I did a search and couldn't find this posted so I wanted to share it in hopes of helping others out. So for those of you with lag, give this a shot and let me know if it helps you out. If it does, maybe we can discuss why this works and what the root cause of the problem is in the first place.
u dont need to install 3rd party cache cleaner in android now (ICS and JB)
go to settings>Storage>cached data
click on it and clean it.
and please this is well known method so please use search before starting a new thread.

I'm trying to figure out why my phone is so low on space. I hardly have any apps installed, but it still says I have about 6MB free. Some of the apps have downloaded extra things they need to run (like this translator app), but all of that is stored on the SD card to my knowledge.
What is the fastest way, short of naming off every app I have to you guys, that I can figure out what files or files are taking up so much space on my phone?
go to settings, applications, manage applications ..there hit menu and sort by size .. you might find out that your browser and market cache are huge. select them and hit clear cache

yea the cache for many apps can do that to you
simplest way to avoid that is by moving cache to the sd card (just search for a guide, there are many )
Well surprisingly, no cache was that big (just a couple of megs). I can't really figure out what's so big on this thing.

do you use the google maps a lot? When you organized it by size were there many apps over a meg?
Root your phone and use Apps2SD and stop worrying about the lack of space.
Have you used any kind of program to backup your apps before a flash? The only way I know of fixing it is to get into recovery and do a FRESH wipe and fresh reinstall, then manualy add all your apps back. Should clear things up.
Hey guys,
I have some doubts in the cache in phone which need your expertise in.
Why is it that sometimes our phone will get sluggish and laggy, and we need to reboot it or clear cache to make it back to fast again? I thought in Android (linux), that ram is needed to run any applications and it does not depend on the space (data storage) we have left in the phone. So what does clearing cache has to do with the performance of the phone?
Thanks for your time.
Anyone have any ideas on this?
What are you talking about specifically? Clearing application cache? Doing this will have ZERO effect on device performance ***EXCEPT*** when running THAT SPECIFIC PROGRAM. It could make that program itself faster or slower to clear the cache. The purpose of cache is to improve performance by making the data available locally, however, if the data required is NOT IN CACHE, then having cache will slow it down as a result of having to process the cache.
Note: If you are running a custom hacked firmware using swap or compcache, then rebooting will clear some things up and make it faster. This is another form of cache that gets cleared. Ultimately, without frequent reboots, use of swap will tend to slow the device down over time, and this is cleared by rebooting.
Erm oki, so is it better to do without swap in this case as i'm using a custom firmware?
Let's say I am running 1 foreground application with 5 background applications (sleep) and another side running 1 foreground application with 15 background applications (sleep). This is just an example. In this 2 cases, will the speed of running the 1 foreground application be the same with the different number of background applications there?
Anyone have any ideas on this?
No one know anything about this issue?
I guess it's because the database gets huge and this may be bad for the performance...
so like a big registry in windows is bad...
maybe also some fragmentation... who knows
Ever since I updated my nexus to Froyo, when I'm using the browser itll start to take up all of my available memory causing me to get the low storage warning and sometimes stop me from getting text messages. The only way to free back up the memory is to go force close the browser, which is sometimes using up to 80 mb of data. Ive already tried a factory data reset and also went into the recovery and wiped and clear the cache. I never had this problem in 2.1 and its really annoying. anyone got any ideas? thanks.
forceclosing the browser wont clear up cache.... scroll down instead of forceclosing, and hit clear cache. dont do it through recovery
I am having this problem too D:
Yeah, the browser doesn't seem to limit cache, although I've never seen it use 80M. Most I've seen is 7M. I just clear cache through the Applications list, although in Froyo you can do it directly in the browser now.
if you visit the google forums, the android team has changed the browser in 2.2 to cache the pages you have open in your browser much more aggressively, so that when you go back to the browser the phone doesnt need to refresh the network and reload the page. i posted a link to the google topic before. but what this means is that the browser now takes up huge amounts of space as time goes on. killing it does bring back the space. personally i like this change, but i can see why it might suck for some people.

i posted against this issue, because i happen to like what they did to the new browser. god forbid they go back to the old way, it was not good.
I agree, the browser is better this way in some regards, but it needs to LIMIT what it does... If you don't manually clear cache it'll easily take 8+ megs of storage!

but its not the cache, its just a temporary storage usage. if you force close the browser, it regains back that storage. at least for me it does. my actual cache in the browser never changes, and hovers around 7mb.
Aaaand we're not using A2SD why???

Ah, sorry, I got off topic then.. I was talking specifically about the browser cache, which for me varies between 4-8.5M it seems.. and I clear it because otherwise I'm <20M

Simple solution
Friend was having the same issue but this was pre-froyo.
Found out that after viewing articles on the news and weather app and also viewing webpages she was just hitting the home softkey to return to the main page. This was causing new window after new window of fully loaded websites to be cached out of memory and into storage.
Although i agree there should be a caching limit on the browser there should also be an effort from the end user to close the unused windows when done (easily done through the windows menu). Also after using the news and weather app and any other app that uses the browser to display pages, it should be good practice to use the back button and not the home key.
I've always done that and now my girlfriend does it and guess what... its not an issue anymore.

Except that you can't use the back button in the browser if you've been browsing a lot, you'll be going backwards through a bunch of pages. And if you've logged in, you can't go past that at all as it'll want to repost data etc...
One could close the window I suppose, which would load a default homepage, then go back, but that's tedious.

Tedious? Thats almost as bad as that YouTube review of the Nexus where one guy said he had to move his hand "All the way up to the top of the phone" just to switch it on. (Surely we've all seen it?)
I wouldn't say tedious, just something to get used to. Sadly Google aren't quite there with their Google MindReader beta for Android but until then menus and manually closing windows work just fine ;-)

Steps to properly exit browser
Menu button
Select Windows option
X on all open Windows
Back Button
Not exactly "move hand to top of phone".
And again, my major complaint is about the lack of a limited browser cache, ie: html, css, images, cached for later reload. It grows over 8M, that's really too much IMO. Should be able to limit it, in which case I'd likely limit it to 2-3M myself and see how it worked out.

Actually I do that quite a bit. But you don't even have to. After you close all windows, it defaults to open a last page (Google home in my case), then just hit home cause there's nothing left to cache anyway, so back button or home button does the same thing, makes no difference.
hmm in my case it's also not the cache which makes the problems, but the "Data" of the browser app.
It easily exceeds 28MB!
And cache is only at 600kb, so clearing cache doesn't help.
Clearing the data helps. but it will delete all your bookmarks and other settings which is bull****.
Force closing the browser didn't help too (it helped in the past but interestingly not today).
Browser can not be installed on sd card. System updates can not be installed on external memory.

What? From apps, manage, all, find browser. Clear cache there. That does not clear up your 28M in ram?
So a friend of mine updated his T-Mobile UK Samsung Galaxy S to the official 2.2.1 JPY firmware using Odin a few weeks ago. This went well, and is the same firmware that I've had on my unbranded SGS since December.
However, he has an interesting problem. Some of his apps (Handcent, Dolphin HD, plus a few others) seem to forget all of their settings every time the app is exited. For example, every time he goes back into Dolphin it enters the setup wizard as it it's being ran for the first time. This doesn't happen on every app, and it doesn't happen every time.
I noticed there are a couple of other threads on here with people reporting similar issues on custom ROMs (with no solution), but this is a stock ROM from samsungfirmware.com and certainly doesn't happen on my SGS, so it's not the ROM to blame.
Anyone know of a fix?
This question posted in the last few days .

As I said in my post "I noticed there are a couple of other threads on here with people reporting similar issues ... (with no solution)". I wasn't being lazy and just starting another thread without doing some research first. I've read the other threads and they do not contain a solution that will work for him.
I'm assuming you're referring specifically to this thread? http://forum.xda-developers.com/showthread.php?t=992335 In my friend's case, rooting is not an option, so this solution won't work for him.
However, based on that it looks like a factory reset may fix it. If I don't come back people reading this can assume it worked.
Hello
I experimented the same issue.
Looking at some log traces event it reported some permissions errors on intestinal filesystem like database location access write errors. This can explain setting persistence trouble.
After various workaround, bypass or others kind of fallback I did a full reinstallation of filesystem including a wipe data of the system. Take care to backup application and sensible data SMS, photo...
Since all is working fine and no more problems with settings
I don't know if it's helping you.
This is just my personal experience on this same problem.
Perhaps more simple solution is possible

Thanks. So far so good after a Factory Reset. If it were my phone I'd be looking at Logcat, etc, too, but it's a bit hard to do remotely.
It's odd how some apps saved their settings fine, but some don't.
A factory reset did fix it... for a while. But then other apps started suffering from the problem.
So I've been researching this a bit more today. Here's what I've discovered:
The problem is unique to Samsung Galaxy S phones, and appears to be only ones running 2.2.1 (but maybe 2.2. too?).
Samsung have renamed /data/data to /dbdata/databases, and shared preferences for applications are persisting in this folder even if the application is uninstalled. If you install the app again, the app becomes a different user from the one that owns the shared preferences.
For example - If you install some random application and you look at its process running with the ps command, it will show as "app_XX", where XX is some number. For our example here let's say it shows as "app_55". When it then saves its settings in /dbdata/databases the folder the settings are saved in will have owner (shown by ls -l) as "app_55" too. That's fine, and normal.
The seed of the problem is sewn when you uninstall the app. Those shared preferences are not removed. Even using the "Clear data" option before uninstalling doesn't seem to help. If you then install the app again and look at the output of ps you'll see the new app is "app_56". The shared preferences are still there from last time with owner "app_55", hence the permissions error when it tries to save its settings, as user app_56 cannot modify user app_55's files.
A factory reset obviously cures it as this, at least temporarily, as it wipes the data in /dbdata/databases.
If you're rooted, you can go into /dbdata/databases and delete the relevent folder for the application that's having the problem. It will be recreated with the correct owner next time the app saves its settings.
I didn't try chown to change the owner to the correct one, but maybe that's a way to keep the old settings and correct the problem.
Bingo. No wonder my titanium backup is not remembering the preference settings.
I have noticed that I have folder when cleaning cache by clean master with name Moment.me. I did run a full system scan using CM Security and nothing was found.
To explain this matter more in detail. When I open my bank app somewhat is creating an folder in emulated storage by name imagecache. Then when I scan cache using clean master, clean master is telling me that that folder is from uninstalled app from moment.me which I never had anyway. And this is only when I access my bank app. It's like it some kind of logger or trying to be a logger, by either keylogging or image capture cache something like that. I searched all Google to see what comes when typing Moment.me. Can somebody tell me what this is. It doesn't feel good knowing this. Second isn't uninstalled app being deleted from Android all the way. How can there be a left over and if no app. Who creates image cache folder? Which app does that when accessing bank app. And that antivirus doesn't recognize this stuff but recognize which app did that which was never installed in first place. Tell me what you know. Tnx
P.s I'm using stock lg l90 never rooted. Its on KitKat 4.4.2 have no shady app installed on my phone except that I tried yesterday opera max, some onvo data limiter not sure about exactly onvo but something like that and some other data limiter software. I think its with first in search. Blue icon. Please help
Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers.
Stand by
Good luck
