    Did you tried any apps to fix this problem? There are many apps aims to clean phone memory and optimize ram usage.
    Like cleaning apps, boosting apps.
    You can find a dozen of those apps on Google Play saying they can solve low memory issue.

    I have a slow Android and tried some of them, like all-in-one tools to do phone optimization. some of them works well.

    I never recommend those kinds of apps. They tend to cause more problems than they solve, and they usually do things that are counter to the way Android is designed to work.

    Please see this article, which explains why these apps are counter-productive.

    Android isn't like Windows. Android runs more efficiently when RAM is full, rather than empty.

    Okay, so I'm rehashing a lot of what's already been said here, but I note that there appears to be no definitive solution to this problem. Since there are so many people who have had this issue in one form or another over the course of a number of years, I find it utterly ludicrous that there is no apparent fix to the problem.

    I am running Android 4.2.2 on a Huawei Ascend Y320-U10, and am unable to install or even update apps due to "insufficient storage".

    Whoa, now hang on! I know some of you will be chomping at the bit to tell me that internal storage is equal to X amount, while Y space on an SD card is irrelevant to the installing of apps, and Z MB free in phone storage is not the same as the dedicated app installation memory, yadayadayada...

    Rest assured I have read a great deal about this problem, including this entire thread, and another on here relating specifically to Huawei phones, and am only now posting this because I am at my wit's end and have discovered no feasible solution to the problem. My so-called smartphone has turned into little more than an overpriced paperweight, and I am at this moment totally unwilling to engage in a factory reset. Surely, surely there's a way around this that doesn't involve starting from scratch?! I know it's as cheap and dirty a phone as you'll find, but seriously, is there really nobody out there who has managed, over the course of the past several years, to figure out a way to get around this without simply snapping the device in half and forking out for a better one?

    While I have no doubt that it's quite possible that such action is the only reasonable way out of this quagmire of OS confusion, let's call that the last resort, shall we? In that spirit, if anyone can offer any help that pertains to my particular circumstances and doesn't involve deleting the entire contents of my phone, I would greatly appreciate it.

    So then: I recently tried to update an already-installed app whose total size is *drumroll* just under 20MB. Please keep this figure in mind, as it's going to be important shortly.

    My phone's memory is partitioned into three units:
    • Internal storage, clocking in at a staggeringly enormous (-_-) 1 GB
    • "Phone storage", totalling 1.22 GB
    • And of course, my 32GB SD card


    Now, unless I am much mistaken, apps are installed on "Internal memory", since after all, that says that I currently have 762 MB of apps installed there. "Phone storage" gives me no breakdown as to how its capacity is being used, but it tells me that it has 1.04 GB free, of the 1.22 GB total.

    So "Internal storage" says it has 101 MB of space available - yet I cannot update an app whose total size is no more than 20 MB. When the error message appeared during the update process (and, let me be clear, this has been happening for a number of months, but I have largely ignored it until now, since only the app I'm currently trying to update is something I really care about having work on my phone), there was maybe 30 MB free in "Internal storage". I have since cleared out a further ~70 MB by uninstalling every app I'm willing to remove and clearing almost all cached data from the remaining apps (by "almost all", I mean there is some 450 KB of cached data left).

    This, however, has apparently gotten me no closer to being able to update said app.

    After seeing some of the discussion on the previous page, I decided to try shutting down a bunch of processes, i.e. unnecessary running ones and practically all cached ones, in the hope that freeing up some more of the 512 MB of RAM might allow the update process to proceed normally.

    I went from ~112 MB of available RAM to ~175 MB by doing this, but this, as I suspected, made absolutely no difference.

    Can anyone offer an alternate solution, or at least a different tack, that allows me to keep my current system intact and addresses the issue of what is obviously a stupid software error of some sort?

    I'm also under the impression that the memory might be displaying improperly, since it's telling me that my 32 GB SD card only has 3.36 GB available, despite the fact that the total of the breakdown amounts to only around 11 GB. The memory allocation status bar seems to support this theory, since only about a third of it is full, with the remainder showing up as available memory. But even if this is the case, I've still definitely freed up 70+ MB of Internal memory by deleting apps, so the main issue must lie somewhere else.

    Any thoughts? Thanks in advance for your help.

    Welcome to Android Central! Sorry to hear about your frustration. A screenshot of your Settings>Storage screen may be helpful: http://forums.androidcentral.com/amb...d-central.html

    My guess is that your phone's total internal storage is partitioned into an App Storage area and an "internal SD" area, as discussed in the guide part of this thread. I'm not sure which of the ones you list is is the App Storage area--it could be either, which is why it would help to see the Settings>Storage screen.

    One thing to be aware of is that just because your free internal storage is greater than the download size of the app you want to install, it doesn't necessarily mean that you'll be able to install it. First, the size of the download doesn't correspond to the actual size of the installed app--this is usually significantly bigger, just as with any Windows program (where the .exe installer file is usually much smaller than the fully installed program). Second, Android has a low storage threshold below which the Play Store may prevent apps from being installed--see this post: http://androidforums.com/threads/the...oblem.1004573/

    Thanks for your reply, B. Diddy - I hadn't seen that post in my wanderings, so I'll try a few of the things suggested there and let you know how I get on.

    One thing I am absolutely certain of is that this is nothing to with insufficient storage space. The size of the app that I gave above is the installed size, not the size of the download (since I already have an older version of the app and am merely trying to update it). In addition, I know that I have installed apps on this phone with the amount of storage currently available, and even less - after all, that's largely how it got to the point it was at when I first tried the update, where there was even less storage space left than there is now, before I removed most of the installed apps! If I had been unable from the get-go to install apps with the amount of space I currently have available, the memory would never been as full as it was. So there has surely been an error or malfunction somewhere - though I acknowledge that there does seem to be a problem with memory reporting. As mentioned above, though, I have also deleted over 70 MB of content since then, so there is no storage-based reason why the download is failing.

    If I stumble across a solution with the info you've pointed me towards, I'll be sure to post it here for the benefit of others - since my original post I've talked to a number of friends and people at work about this, and have discovered that this seems to be quite a pervasive - even commonplace - problem affecting Android phones in general, not simply the lower-end models. Might be time for the powers that be to investigate this widespread strangeness in the OS they're busily marketing, and to address this matter properly, perhaps?

    That is a very good article properly explained with exceptional clarity and choice of words



    So you just got your brand-spanking new Android phone with 4 GB of memory, and you can't wait to fill it up with apps, apps, apps, as well as texting everyone and their mothers just how cool your phone is and trading funny photos and videos. But wait! What's that warning that just popped up in your Notification Bar--"Low memory"?!? How can a phone with 4 gigabytes of memory be low already? Besides, you plugged in a 16 GB microSD card, and the Storage menu shows that there's 14 GB free there, so you should have plenty of memory, right? What the ...?

    To understand this kind of problem, it's important to understand how memory is allocated and used in Android. Older Android phones (ones that came with Android versions up to and sometimes including 4.0) typically break up storage memory into 3 main partitions (i.e., areas):

    1. Application Storage: Where Android installs apps. This can range from as little as 256 MB to 3 GB, depending on the phone. Lower end phones usually have less storage, and therefore can have fewer apps installed at one time. Data that the apps generate and save on the phone may also be saved here, although they might also be saved in one of the 2 other areas below. When you start to approach the Application Storage limit, you start getting low memory warnings. You can free up Application Storage by moving some apps to #2 below, but you can never move the entire app, because some key elements need to remain in Application Storage.

    [TIP]To move an app to Internal Storage, go to Settings/Apps, select the app, and tap "Move to Internal Storage."[/TIP]


    2. Internal Storage aka Internal SD Card aka Phone Storage: This part of the phone's storage goes by a few different names, as you can see. Don't be confused by the term SD card--if it says "Internal SD," it's referring to the nonremovable memory that the phone came with, not the card you insert. It can be used for storage of data, either by the user (i.e., photos or videos you take, music files you keep stored on the phone) or by the apps. As mentioned above, you can also move components of an installed app here by going to Settings/Apps, selecting the app, and tapping "Move to Internal Storage."

    The amount of Internal Storage can vary from ridiculously low (around 120 MB) to a lot (like 16-32 GB). Keep in mind that when a phone is advertised as having "8 GB of memory," not all of that memory is available to the user. About 3-4 GB is usually taken up by the operating system and other preinstalled apps (aka bloatware). If the phone came with very little Internal Storage (and really cheap phones usually do), then you end up not being able to do a whole lot. You can't install a lot of apps because the Application Storage runs low, and you don't have much Internal Storage to move apps to. And data generated by apps also fills up memory.

    Here's a screenshot from my Razr Maxx (running Jellybean 4.1.2, but originally came with Gingerbread 2.3.6, with 16 GB of onboard memory and a 32 GB external SD card), showing Application Storage and Internal Storage:

    Attachment 82001

    [NOTE]Notice that my Application Storage is 3 GB. Also notice that the total Internal Storage available to me is actually only 8 GB, even though the phone was advertised as having 16 GB of memory. This is because you have to subtract the 3 GB allocated for App Storage, about 3-4 GB for the OS, and another 1-2 GB for bloatware, leaving 8 GB.[/NOTE]


    3. External SD Card: This is the physical microSD card that you can remove. Most phones can handle up to a 32 GB card, which seems like it should greatly expand your phone's capabilities, but the problem is that the external SD card can really only be used to store media files (like photos, videos, and music), and as an ancillary storage area for some apps (but not all). You generally can't move apps to an external SD card because removing the card (purposely or accidentally) would then cause the app to fail and possibly destabilize the system. That being said, there are some apps that supposedly can move a whole app to the external SD card (search on Google Play for "app2SD"), but they often warn that it may not work on Android versions 4.0 or higher. (There are also ways to do this on rooted phones, but rooting is beyond my personal scope of knowledge.)

    Here's a screenshot showing External SD Card storage:

    Attachment 82003

    [TIP]Notice that in both of the screenshots, you can see the name of the actual directory of those storage areas (/storage/sdcard0 and /storage/sdcard1).[/TIP]


    Starting with Android 4.0 (actually 3.0, but that was only for tablets), phones started to come with what we might call "unified storage," where there was no division between App Storage and Internal Storage--it became one big partition, which allowed you to utilize the entire available memory for app installation. The main drawback was that you could no longer plug the phone into your computer via USB cable and access it as "USB Mass Storage" (where it essentially acts as another drive). With the old system, even when the Internal Storage and External SD partitions were mounted by your computer as external drives, your phone could still function, because the crucial App Storage partition was not mounted (and therefore still accessible by your phone). However, trying to have the computer mount a unified partition would render the phone inoperable while plugged in via USB, because the whole partition would be unavailable to the phone, including all of its apps. That's why newer phones only have the MTP (Media Transfer Protocol) option when connecting via USB, not USB Mass Storage. MTP gets around that problem, but limits your computer's access to folders on the phone. But MTP is a topic for a later day.

    Here's a screenshot from my 2012 Nexus 7 running Jellybean 4.3, showing only the unified Internal Storage:

    So what should you do if you get a Low Memory warning? Try some of the following:

    1. Text messages can take up a decent amount of memory, especially if you've never deleted any, and most certainly if they contain multimedia (photos or videos). Delete text message threads regularly.

    2. Most apps have a cache, which is where they store temporary data. Some can build up really big caches, and this can take up a lot of space. You can always clear an individual app's cache by going to Settings/Apps, selecting the app, and tapping "Clear Cache," but it's easier to install an app like App Cache Cleaner and use it on a regular basis.

    3. Go through all installed apps and uninstall any apps that you never or hardly use. If you realize later that you do need one of them, it's simple enough to reinstall it. Unfortunately, there's no easy way to remove preinstalled apps (aka bloatware) unless you root the phone (hack it to gain complete control--risky for novices). If you have Android 4.0 or above, you can Disable apps by going to Settings/Apps/All, selecting the app, and tapping Disable. This won't remove the app from storage, but will prevent it from opening, and therefore from generating any data that has to be stored anywhere.

    4. Move all media files (photos, music, videos) from Internal Storage to the external SD card. Also, if you take a lot of pictures, go to the Camera app's Settings and change the default storage area to external SD. If you have a relatively small SD card (like 8 GB or less), and it's already getting pretty full, then make use of all of the many cloud storage options you have, like Google Drive (of course), Box, Skydrive, Flickr (1 ​terabyte of photo storage!), and more.

    5. You can also move apps to Internal Storage as mentioned above by going to Settings/Apps, selecting the app, and tapping "Move to Internal Storage" if the option is available. Not all apps can be moved, and if you don't have much Internal Storage to begin with, this won't help you that much.

    I've seen this on a couple of Tecno tablets and the closest I got to freeing up space was by:
    1. Cleaning out the device's cache.
    2. Cleaning out the cache of every single installed app (painstakingly long if there are many apps).
    3. Searching for a hidden, undocumented service menu.
    The first and second steps helped albeit to an unimpressive extent.

    With Samsung devices, steps 1, 2 and especially 3 help a lot. By dialing the USSD:
    *#9900#
    A hidden, undocumented service menu appears. Select the option "delete dumpstate" (second item on list it should be).

    This has worked on the few Samsung models (phones, phablets and tablets) I have sampled, including mine.

    Not all devices support the ability to move apps to the SD. I see from your other posts that you have an Alcatel OneTouch Pixi, which is an entry-level phone that I assume comes with very little internal storage. These kinds of phones are very basic, and are mostly good for making calls, texting people, and browsing the web. You can install a few apps, but the low storage prevents the user from installing a lot of apps. If my tips at the beginning of this thread didn't help, then I'm afraid all I can suggest is to upgrade to a phone with more storage memory, or resign yourself to the fact that your current phone isn't capable of acting like a flagship or midrange device. Sorry!

    Hey, I have an honor 4C and I recently got a new Remax 32Gb sd card. So now sometimes when I try to move an app to it it gives me "not enough space" error. And so I scanned the storage with the system scanner and it shows 588GB of cache. WTF ! and so i checked the apps and sometimes Snapchat and sometimes Facebook Messenger show 1TB or 500GB as their Data. Why is this ?? But if i restart the phone its all fine.
    But the problem comes randomly. I thought it was the Marshmellow update so I rolled back to lolipop. But its still there , I would be so great full if you could get me a solution. thanks
