Fwd: Android Storage: What Nobody Bothered To Tell You

This is the information I have been searching for a long times !!

But you must know your own phone, which is different from author

Android Storage: What Nobody Bothered To Tell You




My experience with Android only dates from end-November 2011 (heck, I'm a Luddite, I resisted the temptation!). And it's still mostly Gingerbread-based.
Therefore, I was surprised to read in several Android forum and websites that people were complaining for not being able to move apps to the SD card on Android 4.0 ICS and 4.1 JB devices ([1], [2], [3], [4], [5]): I was used from Gingerbread that I could use the App2SD built-in mechanism (no need of an external app) to move apps to the SD!
Sure thing, apps wouldn't move entirely on the SD, but in most cases at least 40-50% of the space that used to take from the internal storage would be taken from the SD, and in the happiest situations, up to 80-90% of the app would move out of the internal storage.
So, what's the deal with Android ICS and newer? Is it a regression? Let's try to explain the real situation.
Prior to Android 4.0 (up to and including Gingerbread 2.3, as 3.0 was for tablets), phones were typically having this storage layout:
  • "internal storage" (fast, eMMC), often limited to a meagre 150…160 MB, sometimes up to 1…2 GB or more. Apps would install here. Apps also create cache and data here.
  • "SD card" (optional, assumed to be external). People would add microSD cards to be able to store music, pictures, videos. Since Android 2.2 Froyo, there is a built-in "apps2sd" mechanism that allows moving apps partially to the SD card. Data created by apps as part of the initial installation (from APK) usually cannot be moved. Many apps that require downloading of extra data files post-install (not from Google Play), such as dictionaries, games, etc., usually know to save such data on the SD card, if present. If you check /system/etc/vold.conf (or vold.fstab), the card is mounted under /mnt/sdcard.
Now, not only that apps cannot be moved entirely on SD, but the built-in "apps2sd" mechanism also has a limit of how much it can keep outside the "internal storage". I couldn't find any documentation on that, but on a cheap LG phone, Quick System Info PRO reported a 236 MB limit:
A2SD storage: an annoying limitation
This issue can be workarounded, on rooted devices, by creating a supplementary ext2 partition on the SD card, then useLink2SD; to move apps on that extra partition. When using apps such as ROM Manager, this partition is limited to 512 MB — so in my case I could only get about 160 + 236 + 512 = a maximum of 908 MB for apps.
Obviously, those cheap Gingerbread phones are very limited, and Google makes them practically useless nowadays, as forced updates of Google Play, GMail, Maps, YouTube, Google Talk (now Hangouts), plus the addition of Google Play services take about 50 MB of "internal storage". Unless the phone is rooted, these updates to system apps cannot be integrated into ROM byTitanium Backup.
Now, even under Gingerbread, there were phones with 8…16 GB of ROM.  After subtracting the memory taken by the firmware, was the available space entirely partitioned as a unique "internal storage"?
Typically, no. Because of the costs, eMMC chips are usually not larger than 4 GB, therefore the rest of the storage was a sort of an "internal SD" card. Some such phones (or tablets) don't even support an additional SD card, but when they do, here's what their storage layout:
  • "internal storage", usually less than 2 GB. Apps would go here by default.
  • "internal SD" (oftentimes labeled "phone storage"), the rest up to the limit of the available storage space. Mounted as/mnt/sdcard. Apps can be moved here (some even install here by default). Of course, this is the place where your photos and media files would go.
  • "external SD", if the device supports SD cards, and if one is inserted. Mounted as /mnt/sdcard-ext/mnt/sd_external or/mnt/external_sd. Apps CANNOT be moved here! Media files can be saved here though.
Here's the storage of a cheap "8GB" Android 4.0 tablet: 1.15 GB of "internal storage", plus 5.78 GB of "internal SD" (for a total of 6.93 GB):
chep_tablet_storage
NOTE: The above screenshot is taken from a tablet. On a phone, the second "Internal Storage" would have been labeled"Phone Storage".
The problem with today's Android devices — being them 4.0 ICS or 4.1-4.2 JB — is that they're inconsistent in the way the internal and external SD partitions are used:
  • some devices are using a "unified" internal storage (à la iOS): a single partition for everything, and no external SD card supported (Nexus 3, Nexus 4);
  • some devices are using a "unified" internal storage, and when a SD card is added, it can only used for media files (apps cannot be moved there);
  • some devices are using a "unified" internal storage, but when a SD card is added, apps too can be moved there — the card is mounted as "internal SD";
  • some devices are having "internal storage" + "internal SD", and when a SD card is added, it can only used for media files (apps cannot be moved there);
  • some devices are having "internal storage" + "internal SD", but when a SD card is added, apps too can be moved there – the "internal SD" is actually mounted so that Android believes it's "external SD", and apps cannot be moved there, but an added SD card is mounted as "internal SD", so apps can be moved to it!
The last variant is a nice hack, as it allows for cheaper internal storage (split in 2 partitions), yet the space for apps can be extended through the addition of a SD card. Some HTC and Huawei devices hack Android to do that. In contrast, Samsung and LG are known to use the 4th approach — apps cannot be moved to the external SD card (Samsung has currently started deploying firmware updates that would change this for some devices).
I've made a research for some current models on the market, and in some cases I have double-checked on forums that the storage model for the investigated models are as follows:
Sony Xperia Z (5″, 4.1.2, 530…580 €)
  • 11.73 GB available (out of nominally 16 GB)
  • unified internal storage
  • will not install on external SD

  • 7.65 GB available (out of nominally 16 GB)
  • unified internal storage
  • will not* install on external SD
  • *a firmware update should allow apps to be moved to external SD as well (GT-I9505)

  • unified internal storage
  • will not install on external SD
HTC One X 32 GB version (4.7″, 4.0.4/4.1.1, out of production)
  • confusingly reports 25.24 GB available, but also 6.76 GB for applications, of which about 5.4 GB are already used with 4.1.1 (25.24 + 6.76 sum to the nominally 32 GB), so in fact it has:
  • about 1.36 GB internal storage + 25.24 GB internal SD
  • will not install on external SD
LG Optimus G (4.7″, 4.1.2, 499 €)
  • 25.04 GB available (out of nominally 32 GB)

  • quite a shame for a 2013 model!
For the devices that cannot move apps to the (external) SD, some hacks are available if you root the device. Apps such as Root External 2 Internal SDMounts2SD, or GL to SD; can do what the manufacturer of a device didn't bother to: mount the external SD as "internal SD", and, if needed, declare the "internal SD" partition as external. Custom ROMs exist sometimes for the same reason. Or you can just edit /system/etc/vold.conf (or vold.fstab).
Now, to cheer up, let's watch an educational video issued by Huawei and demoed on the new 6.1″ Ascend Mate:
Bottom line: ALL the smartphone reviewers are incredibly stupid and ignorant not to check and mention how much storage space is available for installing apps, and whether this can be extended or not (mostly not, nowadays) by the addition of a micro SD card!
__
P.S.: I hate it when I see the "internal SD" part of the internal storage (usually in phones who don't support a SD card) labeled or called "USB storage". It's never "USB storage", but a moronic way of saying "this is the part where you can transfer files to and from via the micro-USB cable".
CLARIFICATION FOR THE UNDERBRAINED: When in the management screen for an app you see the storage occupied with the following lines:
  • Total
  • App
  • USB storage app
  • Data
  • SD card
and a button "Move to SD card", what happens if you tap that button is that parts of the app are moved… to "USB storage", because "SD card" is the external SD card, not the 2nd internal partition!
To avoid this limitation (an external SD card can have 32 GB or even 64 GB), some ROMs are hacked to mount the external SD as "USB storage", and the 2nd internal partition is mounted as if it were an external SD! Android will NEVER be able to install or move apps in more than ONE extra partition in addition to the first internal partition!
__
*IMPORTANT NOTE (OCT. 2013):
The Huawei phones marked with* (Mate, G615, G700, G740, P6) do not have in the system information screens a note like some other models (G510, Y300) saying "only 1.12 GB available for applications", however they might have a similar limitation of about 1 GB for apps, despite the storage looking like unified!
On a Huawei Ascend G700, Quick System Info PRO reports a so-called "System storage" (that is nowhere explained) of 0.99 GB, of which 270 MB are free. Depending on how they define the GB, this suggests 730…744 MB being taken by some apps, however the phone reports only 547 MB as taken by apps:
huawei_g700_info1
LATE EDIT — FALSE ALARM: I guess I am just paranoid. I've installed ~300 MB worth of new apps, the "free internal storage" dropped from 3.43 GB to 3.13 GB, yet the "System storage" still reads the same "0.99 GB / 270 MB free"! So I guess it's just some irrelevant and fake thing reported by Android.
Could Android storage be more confusing than that?
JANUARY 2014 NOTES: I have removed some previous remarks (with screenshots) which incorrectly claimed that on some Huawei phones, moving an app to SD wouldn't have moved it to the actual external SD (/storage/sdcard1), but would still keep it in the internal storage (/storage/sdcard0). I have been fooled by the fact that the access to /storage/sdcard1/.android_secureis denied to file managers — but connecting the phone to a PC made it possible to look into that folder and see the ".asec" files.
So no, Huawei's phones are not more confusing that other phones!
I have also discovered that indeed, there is no hidden limitation to install apps into phones such as Huawei G700 (and other models that do not report "only 1.12 GB available for applications"). At some point, where the free internal storage was exactly 0.98 GB, I've got that infamous message from Google Play: "insufficient storage available". It was however just a bug — and another false alarm –, because after I rebooted the device, I could continue to install apps!
As a matter of fact, I've installed 253 appscompletely into the internal storage, having left only 560 MB free! I knew from the times I was using a Gingerbread phone with 153…159 MB of internal storage that 10% of the space is reserved, so the "insufficient storage available" message appeared as soon as less than 16 MB were free, but I am not sure about the settings in Android 4.2.1: 560 MB is less than 10% of the total of 5.74 GB really available (from the nominal 8 GB), yet the system allowed me to do that!
storage1storage2
■ Note how the system reports as "Apps" only 0.95 GB — the app data is part of the "Misc" (3.73 GB), despite the claims to the contrary!
In the meantime, because the 9 biggest apps, with space needs between 94 MB and 160 MB, took 1.1 GB, I've moved (parts of) them to the SD card, to gain some more internal space, and I will uninstall a few more apps when I won't be needing them anymore. It's a good idea to keep at least 1 GB of free internal storage.
■ Oh, moving apps on the SD card won't reveal any new category in the "SD CARD" space report — only the "Available" space will decrease. I'd have liked to have the space counted for the /storage/sdcard1/.android_secure folder…
■ As a matter of fact, it's not clear to me why a practically unified internal storage still has to mimic a 2-partition model — the entire available internal storage is mounted via fuse as /storage/sdcard0, so that an added SD card would become/storage/sdcard1. Of course, on non-rooted systems, some files need not be accessible via a file manager, so they're considered as part of a "system storage" (the 0.99 GB one, which seem to always have 277 MB free, no matter what I do), but still, why make things complex when they can be kept simple?

[摘要]在华强北,手机有几种区分,全新机一般都指水货新机;翻新机是把一些回收的二手机用化学液体清理干净,重新换外壳,配上电池、充电器和包装,当新机销售;"扳机"就是用零件凑出来的组装机。
近日,华强北现代之窗一楼手机卖场人头攒动。深圳商报记者 钟华登摄
很多人有在华强北或淘宝买水货手机的经历,相比专卖店动辄五六千元的高价,冠上"水货"两字,价格就相差数千元。然而你有没有想过,商家所谓的港版、美版手机,仅仅只是产地、版本不一样吗?还会不会有其他猫腻?
近日在某知名网站,一位自称华强北某数码城卖手机的工作人员,曝出了iPhone翻新的整个过程,不仅手机零、配件能翻新,甚至相关串号、序列号、保修期都能修改,令人触目惊心。
针对此,记者采访深圳手机界多位业内人士了解到,受高额利润驱使,高档智能机尤其是iPhone的翻新非常普遍。华强北手机翻新及组装已经形成一条灰色产业链,令人吃惊的是,华强北部分卖场及淘宝不少iPhone都为翻新机。
华强北每天卖上万台翻新机
"在淘宝买到便宜iPhone的小白们,你们觉得自己拿到的都是新机吗?你知道你们买的手机原型是什么吗?"
在上述自称华强北某数码城工作人员的帖子中,爆料者称,去年"双十一"那段时间,他忙得不可开交,原因是他接到很多淘宝卖家的订单,其中绝大多数指明翻新机。
翻新机是怎样"炼"成的?在帖子里,该网友图文并茂地对iPhone翻新过程进行全程直播:
首先去市场收购二手手机,进行外壳翻新。他介绍说,回收到的二手机一般是美版、港版或日版等,分为有锁和无锁。有锁的,客户要求内置卡贴当无锁卖;无锁的,翻新后直接当港版卖出去。
该网友介绍,因为价格便宜,回收到二手机一般都是外壳刮花或整个爆屏,所以首先要换壳、换外屏。
然后拆机准备翻新,其中过程比较繁杂,包括打磨边框、拆开屏幕去压支架、装主板等一道道工序。
翻新后,贴上新机膜,就能拿去打盒标封装了。该网友称,由于淘宝客户都拿去当全新机卖,逼真的包装必不可少,其中iPhone5的背盖、4S的槽码都可以打标,华强北专门有做这个的,几块钱就能做一个。
在帖子中,该网友说,"华强北市场上的高仿配件、原装配件一应俱全,配件由商家随意配置,拿什么给消费者就看商家良心了。"
"一个封枪,一个密封袋。封好后就以全新原装卖给客户。"该网友指出,以他所在的华强北某通讯市场为例,总共有几千个柜台,每天大概能卖出几万台苹果。
据悉,在华强北,手机有几种区分,"全新机"一般都指水货新机;"翻新机"是把一些回收的二手机用化学液体清理干净,重新换外壳,配上电池、充电器(假冒)和包装,当作新机销售;"扳机"就是用零件凑出来的组装机。
翻新机和假货在网上泛滥
翻新后的手机,除了在华强北社会渠道出售外,最主要的网上渠道就是淘宝网。
昨日,记者在淘宝输入"iPhone5",显示有6699个卖家及宝贝。
记者发现,与天猫商城的价格相比,淘宝商家的iPhone5价格明显便宜,基本集中在2500元~4000元左右。
在一家名为"良X发数码城"的淘宝店内,其港版16G iPhone5售价为3200元。记者注意到,该店月销量达1962件,在2820多条用户评价中,大多买家认为"超值划算",其中一半以上认为"手机是正品"。店铺首页,该店以醒目的字样承诺,出售的均为苹果官方正品手机,若用户发现为非原装正品,将免费退换。
当记者以消费者的身份,对可能遇到翻新机表示疑虑时,该店工作人员告诉记者,鉴别翻新机的方法很简单,首先检查听滤筒是否有明显的灰尘,二是观察耳机和USB接口是否有使用留下的擦痕,底部的螺丝是否有扭动的痕迹,同时看HOME键有无刮痕或灰尘。
事实果真如此吗?鉴别翻新机就这么简单吗?
在上述爆料帖中,该网友直言不讳地指出,在淘宝,九成以上的iPhone是翻新机或官换机。"一个拼价格的地方,你能指望买上全新机吗?"
记者昨日采访到多位手机业内人士,他们均对记者表示,淘宝九成以上的手机为翻新机或假货,这个数字并不夸张。而这些翻新机或组装机几乎都来自华强北。
在华强北手机行业工作数年的应先生告诉记者,以他接触到的华强北手机的情况,上述网友爆料基本属实。
应先生表示,在远望、明通、赛格、通天地,你会看到很多iPhone盒子,但不要以为这些是真机,其实都是给水货或者翻新机配套用的空盒。
"更需要警惕的是,华强北的翻新机,不仅仅只是翻新手机,就连背部外壳的串号、序列号,甚至手机保修期都能更改,除非专业人士拆机鉴别,普通消费者根本无法分辨。"应先生指出。
已形成一条灰色产业链
"据我所知,华强北有专门的一群人在做iPhone,已经形成了灰色产业链。"昨日,深圳手机界资深人士吴先生(化名)对记者表示,深圳的手机配套生产非常完善,专业分工明确。即使在一个手机卖场,几千家商铺分类不同,整合起来就能形成完善的产业链。
吴先生告诉记者,目前华强北卖场的手机商户暂无统计数据,手机翻新产业的规模暂时还很难估算。但可以肯定的是,作为华强北翻新手机主要的线上渠道,淘宝九成以上的iPhone为翻新机,甚至不少是假货。
手机翻新的利润有多大?吴先生告诉记者,翻新机的货源一般都是美版、港版或者日版,国外不用的机器,由水客低价回收,再走私至内地。所以尽管无法估算其利润,但可以想象只有利润达到一定程度,才会吸引这么多人铤而走险。"这条产业链条一旦暴露,有可能大得惊人。"
吴先生表示,目前除了iPhone5s的翻新机还不多外,其余机型翻新的都很多,所以提醒大家,购买水货手机一定要注意,不要因为贪图小便宜而上了大当。同时,对于淘宝"双十一",商家超低价售卖iPhone的时候,也一定要留个心眼。
"消费者一旦买到翻新机,不仅仅在价格上吃了亏,更严重的是,有的翻新机可能存在质量问题,容易出现种种毛病,甚至产生安全隐患。"吴先生说。
对此,市消委会相关负责人接受本报记者采访也表示,消委会也接到大量消费者投诉,部分通讯类产品经销商,尤其是网络销售水货和假冒、翻新机等问题比较突出。
消委会提醒消费者,通过网络平台买手机时,慎买价格与实体店相差太远的品牌通讯类产品,且尽量采用第三方支付的方式付款,接收快递时注意查验产品的主配件是否完整。(深圳商报记者 刘双)
