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?
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.
Closed, addressed in other threads
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
Hey Everyone,
my problem is - very often the downloads from Google Play are very slow. (About 300kbit/s)
When I stop the download and go to Apps --> Google Play and then delete the Data, then open the playstore again and download the same file, it will be much faster. (at least one magnitude, about 3-8mb/s)
Any ideas?
My Wifi is the same as before and my internet-provider does provide 100mbit/s, which is being realistic about 50-90mbit/s in real life.
Regards,
Maeffjus
it seems that latest ROM updates (I think I have this on all AUB* ones) is weirdly strict on background activities and cuts every one of them. my whole device acts strangely - apps not showing notification or showing them late (hours later than they were supposed to show), my apps are not updating: I have to repeatedly FC play store, then clear its cache so that currently installing app changes state from downloading to installing, than do it again to change state fomr installing to installed etc. worked fine on AUA* ones. it is really annoying. btw I tried to clear cache and dalvik/art cache from recovery, but that did not help. I have not tried factory seset yet...
I cannot download apps or update apps. Turns out its Virgin Media (UK) blocking traffic. They're sending me a brand new shiny SuperHub 4.
It seems that it was data corruption during regular OTA. Factory reset seems to fix problems for me.
