Android phones have at least 2 fingers in the pot that iPhones do not: the hardware maker and the network carrier. The hardware makers often consider their drivers trade secrets, and therefore must learn the new versions code and then adapt their drivers. Manufacturers also often provide custom "skins" that must be updated for the new version, and sometimes ...

update.zip are never touched by Android. Inside that archive is a script that is parsed and interpreted by the Recovery runtime. The Recovery, at execution, opens the archive by unzipping into a temporary directory, reads the script, aptly named update-script, analyzes it, and based on the syntax, executes a function known to Recovery, that function may do ...

It appears to be random chance. In this reddit thread, Google Employee Dan Merrill says of OS update rollouts and "mashing" the "check for updates button": Rollouts are conducted in phases. Typically they start at 1% of devices for around 24 - 48 hours; we watch the return rates and resulting device checkins and error reports (if any), and make sure ...

This is a 2-part question. Part 1 asks why Android phones do not get the newest update right away, and has been answered adequately by the other answers. Part 2 asks why older phones often never get the newest update, and has not been answered yet. As LeBeau says, there are other corporate stakeholders besides Google. Google only creates the new versions, ...

The only devices that you can be confident about getting timely updates for are Nexus devices. These tend to get updates for at least 18 months and they receive them as soon as Google releases them (they're essentially Google devices made by other manufacturers). All other manufacturers take a while to release an update once it is released by Google, ...

As far as I know it does download just the updates (referred to as the "delta") on Jellybean 4.1 and above. Obviously the initial install is the full app but updates only download the data that has changed from the current installed version (i.e. the "delta" of it). You won't see anything different when updating most app, it will still look like it's ...

No manufacturer makes any promises about future system updates for a device. They would shoot themselves in the foot if they would, because if the device fails to get a good market share the resources needed to keep an device up to date would be lost. I order to ensure that you get updates for your Android devices you have basically two options: Go with ...

The kernel on your device is tied heavily to the version of the Android operating system you're running. Sony releases your phone with the "stock ROM" (think a "stock" car in stock car racing; no customization, just as-is from the factory), including the stock kernel. Normally, your kernel would be updated when the operating system - your "ROM" - is updated. ...

The message is basically telling you that you don't have the correct bootloader version on your device; specifically, you most likely have an older ICS bootloader rather than the Jelly Bean one. You can read a bit about this on CyanogenMod's Google+ page, and the CM Wiki page for the S3 succinctly notes: Going forward, CM10.1 is no longer compatible with ...

I'd be extremely worried there! The MasterKey vulnerability exploit works in the handling of ZipEntry (see below - Bug 8219321), which is buried deep in the ROM itself, its used in the PackageManager layer as well. For such an application claiming "to patch" it, is misleading and false, because it is a user application and not at system level. The real ...

Nope, there will be no official support for Android 4.4 on the Galaxy Nexus. However, you will almost certainly be able to flash custom ROMs that are based on it. There's some supposition and explanation going on on Android Police. They make a few good points: The Galaxy Nexus is old and well outside normal support windows. The CPU Manufacturer doesn't ...

You have to wait until Samsung lets out their update with their added components, or flash a custom ROM onto it. I don't know how to do that, so I won't provide a recommendation. Depending on what network you're on, it may be a little while yet. An article about that.

I think there are a number of reasons why updates are so slow for android devices: The time it takes a manufacturer to apply their customisations to the new version and ensure everything works OK can be quite long. This has improved over the last year or so as Google give them an Android PDK, or the Platform Development Kit which should allow them to work ...

The error [RPC:S-5:AEC-0] is down to having to remove your google account and re-add it again. If your account is primary google account, the only way you can remove it is to factory reset and re-install everything! That is the only known cure and quoted by Google themselves! Do not think they are taking it seriously enough. It broke on a previous update ...

OTA update will depend on the CSC of your phone. CSC is Country Sales Code; it tells you which region your phone can be used in and which networks it will work with. If you are in India (and your phone is connected to an India network), and your phone has CSC for Saudi Arabia, you will not be able to get OTA updates. What you can do is flash a stock ROM for ...

Usually, Google Play Services will always run in the background and if there is an latest release of the Play Store is available, it would updated automatically. You may enable Google Auto Sync and check whether it works. If not, there may be some problem with Google Play Services. Alternatively, try installing the apk from XDA.

Just because Google released a new version of Android doesn't mean that Samsung (or any other manufacturer) has implemented it for any or all of their devices or that your carrier has made it available OTA. Samsung does not appear to have made any announcement regarding if or when the Stellar may receive an update to JB 4.2. You may also wish to keep an ...

As geff described, you cannot avoid a wipe/factory-reset. But you can do a proper backup beforehand, so you can restore most of your data afterwards. This should work without any trouble for the apps you've installed yourself ("user apps"), while special care must be taken for pre-installed apps ("system apps"): As data structures (inside their databases) ...

If all else fails, you can flash those images in Fastboot. Remember to make a Nandroid and back it up somewhere safe - this will wipe your device. If you're on Windows or OSX, you'll need to install Fastboot through the Android SDK. It's part of the "Platform Tools" package. If you're on Linux, you can usually install fastboot through your package manager. ...

Since you bought your phone from Kuwait, the phone has the Kuwait Galaxy Note 2 Rom, and still now the 4.3 update has not been pushed out in Kuwait or the middle east region for both the note 2 and s3. But for the Indian Rom 4.3 has already been pushed out for both the phones. My brother had the same problem with his s3 and since I have some knowledge in ...

Unless you wipe all your data before the update, you do not need to Reinstall applications or Restore application data. But when flashing a completely different new ROM, it's recommended to do a full wipe before proceed. Further more, If you are planing to do a full wipe you can use a application like My Backup Pro or Titanium Backup to back up all your ...

Honeycomb was actually meant for devices with large screens like tablets etc.., There is no Official update for S5300. So you'll have to root your phone and install a custom ROM(such as CyanogenMod) on your phone. Keep in mind that rooting your phone will void your phone of any warranty. Also beware that any error made while flashing ROM could brick your ...

The new version replaces the old version, just like upgrading to a new Windows version or a new version of Ubuntu on your PC. Also, it's not the case that the kernel is the same for ICS and JB. ICS uses a Linux kernel based on the 3.0.1 release, whereas JB's kernel is based on 3.0.31. Android-specific patches to the kernel were also added between the two ...

If you don't use them, there is no point in updating them. The only benefit of updating would be that they will stop giving annoying reminders to update - at least until their next update. Many of these bloatware/crapware additions can't be removed without rooting the phone. However, many of them will respond to a Force Stop after which they won't prompt ...

Did you tried Google Android rooting? Is there something in the articles that your don't understand? Rooting means allowing an application to gain root privilege. This is usually done by hacking the existing kernel or flashing a new kernel. Some devices locked the bootloader, you have to "unlock the bootloader" first in order to flash a new kernel. As ...

You might provide them a link! A link on your website, that would provide them with the .apk file. After downloading, the user would install that file in his android phone. After installing, the previous version is auto-deleted and the new version is installed! User data is saved. But I have never used the developer tools from Google Play. So I am not ...

There's no guarantee that any device will ever see an Android OS update. A Nexus device will probably see two, maybe three, updates (if the past is any guide). Devices from big-name manufacturers will probably, eventually, see one Android upgrade. However, considering the resources needed to modify the Android source to fit with their customizations as ...

Try disabling the notification then restart your tablet and see if it reappears: Go to Settings > Application Manager > All > Google Services Framework and then uncheck "Show notifications".
