Has anyone on EVO come across this problem. I keep getting low disk space on my EVO. I uninstall apps to get more internal space, but then it drops again. On Friday I had approx 48mb of internal storage, then by 4:00pm I had 323 kb. I uninstalled a bunch of apps and now I am back at around 48mb.
I went into sd and storage to monitor my space. I also went into menu settings/ applications to see what was taking up the space. By chance I noticed that my Mail icon in the morning was at about 75mb and when I checked it that afternoon it was at 111mb. I called sprint tech support and we deleted/ then added my email accounts again to see if that would clear up space. We also set the max amount of space for msgs to 25 kb. text only. This seems to be working, but still under my mail settings under applications, the MAIL still shows using up about 95mb of storage.
Sprint tech support states that that is really high, but for some reason it is not something that can be erased. Of course I can always do a wipe, but that is always as a last resort. Just trying to gain back some of that precious internal storage.
Any help is greatly appreciated.
Thanks
In the few years I spent supporting mobile phones for companies low internal storage space was almost always caused by pictures, mp3s, and movies.
So how much of that do you have on your phone?

The EVO saves that kind of media to the SD card.
OP, what ROM are you running?
I know that apps like streamfurious will cache its content and store it to the phones memory. It can Max you out in a matter of hours. Do you use streaming apps?

A misbehaving app is probably the culprit. I'd really recommend Cachemate in the market. There's a chance that one run of that may solve your problem.
Also, if OP is running CyanogenMod w/ Turbo that'll occupy a good amount of internal memory as well.
I use Xiia Live llite. Usually in the evening. . I'll check that out and see if it shows how much is cached.
Thanks
I'll check it out. thanks. Ok it cleared about 3mb.
My mail icon still shows 99 mb of data. If you go menu, settings,applications, manage applications, It brings up everything that you have installed. You can list them by size. The Mail icon HTC, is the one taking up all the space. is there any way to eliminate it? I am running rooted 2.1. I will probably OTA to 2.2 tonight and unrevoke 3.21. Don't know if this will help.
Thanks
I'm running into low storage also.... I have alot of apps but have moved most to sd card that I can... Anymore tips to get storage back?

Question:
Has anyone with an Incredible (or htc device?) ever gotten close to filling up the 748mb's of phone memory? What's your maximum?
I know there's a weird storage notification that comes up w/ the Incredible, and correct me if I'm wrong, no one TRULY knows why it happens, right?
So I'm trying to install the MiniSquadron Special Edition. I get this message: "Sorry, there's not enough space to install this item."
I have 487MB available space free in my 748mb's of phone memory.
Why can't I install this item? I am NOT getting the "Low SPace" or "low storage" warnings on my phone currently.
HTC recommends a hard reset. Took it to Verizon today, the tech told me the same thing. Said it *might* fix things. I actually had to teach him that the 748 mb phone memory was not RAM, but what the phone allocates for apps.
Do I have to hard reset? Any solutions? I have a suspicion that if I DO do a hard reset, and reinstall the exact same things on my phone... the same thing will happen.
So, I reiterate my original question:
Has anyone with an Incredible (or htc device?) ever gotten close to filling up the 748mb's of phone memory? What's your maximum?
Or does everyone get this problem, and there's really only 300mb of storage?
*and to top things off my phone randomly vibrates when the screen's on.

Yes. A lot of people know why this happens. Data for user apps is stored in folder /data/data. This folder is limited to 150 mb. If you get down to less than 15 mb available the warning message starts appearing.
As far as I know, nobody has found a way to expand this limit. Apps that can use up a lot of that space are google earth and saving a lot of emails or text messages. If you're rooted you can use root explorer to look at this folder to see how much space you have available. Only solution is to cleanup old texts and emails or uninstall apps.

oh, so the low storage warning comes from the DATA that apps use, not the apps themselves.
i'll just be diligent in trying to clear out my emails and texts.
do you know why i am getting no low storage warning, but it still tells me that "sorry, there's not enough space to install this item?"
or is it the same thing?
On the market it shows minisquadron special edition at 23mb. I don't know if that means app size only, or app plus data. But I assume since you're receiving that message, there's not enough room in /data/data to install the app.

I'm not sure how the developer that started the thread I'm going to post a link to here feels about me pointing people to his thread, but I think this person has made a good attack on the /data/data problem.
It's worth looking over. I'm a beta-tester for his app, and it's saved me > 50% of the space I was wasting in /data/data. I'm using the linked loop filesystem on the /sdcard approach mentioned in that thread. Google Earth alone was taking 50% of my usage (30M), now is taking ~< 1M).
Anyway, worth checking out::

If you're referring to the notenoughspace app linked above, it doesn't clear your data. It instead allows you to move selected application subfolders to the sdcard, which frees up space in the /data/data folder.
You can clear data for user installed apps thru Settings> Manage Applications. But don't think I'd try that for facebook. Clearing cache is a safer option.
Data for an app is all the information an app needs to run. If you clear data, the next time you start the app it will be like a fresh install and all the required data will just be recreated anyway.

how much memory do you guys have on your Incredibles? how much space is filled up?

I think, for me, that ~750M of memory (and I mean memory for applications) is fine. I haven't yet gotten more than 200M of that in use and doubt I will.
The more important figure isn't memory (DRAM/App Memory), it is what we were talking about above. It's the size of the separately mounted /data/data partition which is, I think, only about ~160M. Even on my relatively sparsely populated Inc, that partition was nearly full. Google Earth uses 30M in just libs there.
That's what NES, the app above, addresses, so there is a way out, especially now that the dev has allowed usage of a loop partition in the /mnt/emmc partition. That allows the /sdcard to still mount with a USB cable without any contention.
Anyway, the thing that made the Droid 1 so slow and easily bogged down was a lack of actual memory (250M if I recall), and the Inc doesn't have that problem a bit. The Droid 1 I had was overclocked to 1.1Ghz but was very slow by comparison to the Dinc. and I think that's all due to the amount of physical memory.
well, the struggle for memory continues...
what would happen if i cleared the data for the facebook app?
it's over 32mb big.
i dont want it to erase all the contacts pics i have set up, although, is that facebook for htc sense? different?
on a side note, i notice that if i periodically clear dialer storage, aka text messages, that helps w/ the warning.
If you are rooted you should be able to move the app to your SD card? Or am I wrong? I use root explorer and I can move any app I download to the SD card.
no, i'm not rooted, unfortunately. maybe this'll be one of the reasons why i root...
anyways, no, i'm not, so i don't have root explorer.
know what clearing data in facebook app does?

Rigman: I never saw this, but was under the impression that cache under the incredible was kept in two categories, one at a system level in /cache which is ~193M and the other at the app level which /data/data/{app}/cache covers. (which is helped by NES}.
So I'm thinking that based on your response, you know that this person's problems with data space are in the system /cache? I was just curious how you knew that. I'm also curious if that problem has been as big a one in general as the /data/data problem which I hear about a lot.
Maybe it can be tackled in some similar fashion by another NES type (or the same one) app.
Thanks,

I have a 1 gb ext3 part on my SD card....
couldn't a soft link from /data/data to a file or directory in the ext3 work
to expand /data/data expanding the space? I guess as long the app opening
space didn't need it until after the sd card is available. Not sure how to
mount the ext3 part tho .... does Android have an equivilent to
/etc/rc.d/rc.local in BSD to issue the mount? or /etc/fstab (with a way to delay
until the right time in boot up)? Will power button power down unmount it?

Yeah, but that is basically how NES works (in my first post in this thread). It creates a loop partition on the /sdcard or /emmc partition, and inside the loop partition is an ext3/4 FS. This was it just appears as a single file, not a filesystem, and can go onto a fat32 formatted 'drive'. That stuff all works fine. There is a mount/dismount ability from either the app or term emulator.
The drift I'm getting here is that this thread isn't all about /data/data. Do you know if that's the case? I guess there is also the old /cache partition and thought I've not experienced it, it probably can also fill up.
I don't know why something similar to the above couldn't be tried on the /cache partition but this possibly gets into a messier world where you have to get in at init.d time and force a different sort of mount to /cache to open it up a bit. It depends on what sort of structure the fs has inside /cache. (and if that's a problem).
Wow, you guys are good! Question is, is there anything I can do? Is this a google problem, or htc problem? Does this internal memory problem happen on motorola droids?
also, why does this problem still exist? Does google not know or not care?
On a side note, maybe you guys can help. When I hold down the search button to start google voice search, and speak something like " call mcdonalds, " it will try to call mcdonalds, and get the phone number correct EXCEPT for adding a " +1" before the number, which means it won't dial. Htc doesn't know what to do except NOT use this function, but to use vlingo. also, my google voice had some numbers show up with a" +1" . It's weird.
I think it's a htc sense problem, cuz non htc phones doesn't have this problem. Also, rooted users don't have this problem either.
Any suggestions? Would a hard reset help?
I have a droid and took a look. It appears to be a Google thing, not an HTC one since my droid has ~95M of /cache and a similar amount for /data/data. It also has much less DRAM and without using the SD card for apps (apps2SD) has more problems than this. (mostly manifested by poor speed regardless of overclock,etc)
Why exist? Take a look at the google bug base, and well, you'll see how many problems exist It's probably low on the list of things to do.
The other bit of this is that flash , although finite, could potentially be arranged in anyway via design. They could have given us more /system, more /data/data, more /cache, but for some reason these are the choices they made. The thing that maybe is unique to the Inc and I'm not sure of this is /mnt/emmc, which isn't hardly used for much of anything, so there was more room available for the MTDBlock{devs} to be used in other ways.
Sorry -- I'm out of answers I'm hoping they do a better job say, in gingerbread, or whatever the lastest bit of 'hot peanut fudge ice cream' OS upgrade that is next on the list. If there is any hardware related restriction (that I can't see right now), then hopefully the fact that our Dinc's are somewhat done for generation-ally will mean that the next HTC's , Motorola's will do a better job from the HW standpoint as well.
INTERESTING...
i had to clear my sd card, so i moved all of the apps that were on there back onto my phone. i have taken up 500 some MB of space on my phone now, with about 200MB left.
VERY interesting. i know that the low space warning doesn't really have anything to do w/ the storage, but the app storage, i just never thought i'd see that much on my phone w/o getting the low space warning.
and i have NOT gotten the low space warning, too, btw.
and i'm willing to bet if i downloaded those apps instead of retransferring them back on my phone, i'd get that low space warning...
I have seen several conflicting threads on this, but no clear solution. Basically, the problem I have is that if I move more than 50 or so apps to my SD card (I have heard others complain about the problem manifesting at around 70 apps) a race condition occurs during the card scan, which since it doesn't complete before a timeout, causes the phone to soft reset (basically reload just the top level OS above the continuously running kernel). These resets then continue to occur at semi-random intervals, such as every time you try to access the memory card. So far, the only fix I have is to delete apps from the SD card, and it really doesn't matter which ones they are, only that above a certain number, the system becomes unstable, and I presume it is because the system cannot index all of the apps fast enough. I can't believe the stupid Samsung engineers never thought of fixing this.
Anyway, I am running a stock, rooted kernel, stock ROM, but the internal memory is nearly full with all of the large applications that for whatever reason cannot be moved to SD. Does anybody have any viable options?
I have heard of some people using app2SD. I have heard of others remapping their external storage to sd_card with the USB storage mapped to sd_card/external_sd. I tried replacing my memory card (Sandisk, 16GB, Class 2) with a brand new, out of box (Sandisk, 16GB, Class 6), and I am still limited to the same number of installed apps. I'm not sure, but I think the number of active widgets on the desktop may also be a contributing factor (all of my widgets are stored to internal memory).
I have about 180 apps on my phone and have never run out of room; what do you have on there that takes up so much space?
if its data, then move that to an external sd...

Well, first of all, I've never removed the Sprint bloatware. I also have the Amazon App store and (on the assumption that my SD card still has gigabytes of storage) pretty indiscriminantly "purchase" and install Amazon's free app of the day, plus all the other apps I've gotten from Google Play. By latest count, it is around 360 apps, and that was after I deleted several large apps that for some horrible reason couldn't be moved to the SD card, including PoolBar (50MB+), Android Phrase Book (26 MB+), some other tennis game I got from Amazon (20+MB), none of which gave you the option of offloaded to SD. About 110 of the apps were games, 25 utilities, 24 media apps, 20 social networking apps, 19 shopping apps, 17 travel apps, 16 PIM apps, 11 photo manipulation tools, 11 internet apps, 8 maps and navigation, etc.
Complicating matters, Android has a /data/data directory which has soft links to all the applications installed on your system, regardless of whether they are installed on internal or external memory, and each link must be the filesystem minimum 4KBs each. Looking at root explorer, I see that this directory alone is over 300MBs of internal storage.
well, the answer to your problem is easy; get rid of 1/2 the **** on your phone that you never use, and you will be fine!
if you don't use it every day or at least once a week, its gotta go

I can't imagine ever installing that many apps, but whatever... If it we me, I would start by trimming off anything you "know" you have never or will never use. After that I would concentrate on putting the biggest apps on the SD card and the rest on the internal. I have 122 apps installed on internal only with much room to spare and I am sure there are things I just will never use. LOL

It really isn't hard to use a bunch of apps, particularly with all the websites, including this one, that have their own viewer apps (or Wikipedia, urban dictionary, etc.). Anyway, I have all my apps in folders so it still only requires 2 pages of apps. I think it is stupid that they designed the operating system so that you would be app limited, even with an unlimited amount of storage via the sd card slot. I hope this is one feature they fixed in ICS. A much better strategy for exploiting the multilevel memory architecture would have been to allow the user to install ALL nonessential apps to the SD card by default, eliminating the need for soft links in internal storage, and then use the internal storage as a nonvolatile app cache with an LRU replacement policy. This would then give the most commonly used apps the performance benefit of running from internal storage without the user having to go moving crap around. It would actually be very similar to what Intel is now doing with solid-state drives as a hard disk cache with the new Z68 chipset.
I seem to have an issue with my internal storage in the Settings app. When I select Storage to display how much I have used it showed 277 mb used in Pictures,videos. I had about 16 pictures/videos in there, along with a bunch of "empty" places. I deleted those empty places and cleared the cache, no difference. I checked the gallery and it showed the same pictures, along with videos from a couple of games, and one game I had uninstalled, Shadowgun. There were two videos and two "empty" videos for Shadowgun. I deleted these four, and instead of going down the amount of space used for Pictures, videos actually went up to 410 mb used. One more thing on these videos, the two were the same, except that one had a path listed under details and the other one did not. All four were the same size, about 30 mb. Any ideas?
Jim
You could try using SD Maid to help you out. Sometimes thumbnails generated by the gallery result in huge (300+ mb) sizes (SD Maid could get rid of them and additional unneeded files for you).
I'm also having problems with internal storage, I'm getting low space warnings with almost nothing installed. I reloaded from stock image and after reinstalling my apps it said I was only using 1gb, my tablet is used as a car stereo so no photos are taken and all media is on the sd card but now 3 days later it says I am using 4gb of internal storage without adding any new apps or adding anything to the tablet also I am noticing my tablet lag horribly sometimes when coming out of sleep. any help would be appreciated

Since you have it in your car, I'm guessing your using GPS nav?
There seems to be a bug with the GPS caching. Check the data/GPS folder for a ton of dated txt files (something like gl-2012-07-01-9573859.txt). And delete them. That folder can grow to a few gb of space of not cleared.
You will have to be rooted to see and mod the GPS folder. Your only other option if you not rooted is to factory reset.

Its good to know whats causing it I will probably stray away from using the gps as much.

Internal storage
I had this issue one of the culprits: gogle play, clear that cache it also stores mp4.
Was getting low storage error and moved a bunch of apps to sd card and my data/data folder showed I had like 80mb free and error went away. Couple days later error came back without adding any new apps and I was under 15mb free, figured this was weird and restarted my phone and it went back to 78mb free.
So what could cause this? Is something not clearing out right here on its own? Btw I am on a stock deodexed rom.
if you don;t install the EXT4 fix, the stock configuration is for the Data partition to be a paltry 149 mb. That can get filled up pretty quickly-mostly by apps like the messaging app, Google Maps and anything else that needs to stored data in this "high performance/secure" location. i put it in quotes because it;s the "official reason" for doing this but I think it;s crap. in reality it;s a design flaw by HTC that never got fixed. also, files from the Playstore get cached to this partion which is why the free space available can jump up and down. there is only so much moving apps to SD Card will fix. the problem is certain apps accumulate data over time.
If you do install it you will have 749 mb available. if you have a rooted Dinc, I think there is no reason not to install it. then again I am not certain if your ROM is compatible. I hear that Touch of Blue has this fix integrated into it if you want to stay on Gingerbread.
this thread probably has all the info you need
http://forum.xda-developers.com/showthread.php?t=1488351
Thnaks man but it's not that, something is just "wrong" with it lol.
It will say I have close to 80mb free and just a few hours later be full. I noticed If I go into Titanium Backup and do some stuff (like removing orphan data) or something it seems to fix it and the low on storage space error goes away and frees up like 60-70mb instantly. This never used to be like this.
Wonder if it's just a sign of an aging cpu or phone not calculating how much free space is there properly.
did you install the fix? if you did not, then do it. the Dinc is a very well known device. Us users have beaten this device to death over the last 3 years. there is not too much new going on. it could be possible that your device is failing and if it is, get a new one.
before I rooted my Dinc, it was a daily struggle for me to keep this partition from filling up. for me the combo of data being consumed by Amazon App store, Google Play store and mostly my email client with 4 email accounts. 149 mb is just too small.
Hey guys,
The storage manager shows me that I use 100 gb from 128
And 60 gb is used by "other apps".
No matter what storage analyser I tried, I can't find where is that 60gb
It doesn't appear in nowhere.
The things is see sums to 40gb +-
Thanks
Gonna bump this because I'd really like to know what it is as well. I have a xiaomi device, and 12gb out of 128 is used by "Other apps". My internal storage is only 7gb in total, system is around 14gb, and apps are 12gb, so this should only total to 33gb out of 128, but 46gb is used out of 128. Really confused.

It's kind of right in front of you.
If you have a NAS drive or a Computer with larger hard drive.
It's time to do some Spring Cleaning.
See all those Images and Videos you have there.... cut and paste them to your PC via regular USB transfer.
that means everything under the Camera folder.
Next major candidate, if you are using WhatsApp and WeChat, do the same thing, but for its own folder.
Then repeat again for any other social media App you have.

Tried this, still shows 11/12gb. Already checked my whatsapp files size, it's included in the whatsapp data section on its info page. All photos and media are shown seperately.
I don't know if this helps or not but about 2 years ago, was working with a coworker and they had a cheap phone with little internal storage, and he couldn't figure out where all of his space went. Come to find out, Chrome was taking up 2+GB! Check app cache for apps you rarely use and clear those, then go from there.

i doubt app cache can amount to 10gb, especially when i dont have many apps installed on MY device. Either way, I use the cleanup tool, which does clear cache, and still see no difference.
