Most cell phones come with a factory ROM update, so you will lose all apps and files.
Some tablets allow a core update and minor OS updates, but they are sparse, and compatibility with apps is not guaranteed.
There usually is no compatibility with major OS updates.
However, if you paid your app from the Google app store, you will be able to redownload and reinstall it once you did the OS update.
Edit: This is no longer the case. With newer versions of Android OS, Google will save the apps you have installed, and it will automatically re-install them for you after an OS update. Also, if you have an older version of Android, there are 3rd party apps that can save both the apps you've installed to re-install later, as well as data from those apps.
No, Belle OS (a Symbian variant by Nokia) does not support Android apps.
No. You need to run android to run android apps. The Nokia E5 runs the Symbian OS.
Can you use Windows apps on IOS? NO! Same for the Pre. it's WebOS. not Android OS!
There are many javascript apps written for anroid os. However, not all javascripts will run on android systems. only those specifically made for android systems will run. It will tell which systems it is compatible with on the download information.
Because your Android OS version may be outdated. And there's no way to update it.
Unfortunatly you can't. This is because on the app store, the apps are written only for the IOS (Iphone Operating System) whereas the apps on the android market are written for the Android OS. The Wildfire uses Android.
No. The kindle paperwhite does not run the Android OS. Therefore, you cannot download Android apps to the kindle paperwhite.
Well, it depends on what your needs are if you are searching for a tablet mainly for reading. The Nook has proprietary apps that are specific to that device that you might not find in a tablet with Android OS. However, you would have limited app choices, and an older Android OS built in with the Nook.
There are some developers that have made an emulator of Palm OS to run on an Android phone. StyleTap is one such emulator, which also allows you to run Palm OS apps. It is available for any platform (Android, iOS, Windows).
No. The Lg 840g does not run the Android OS, which is required to install apps from Google Play.
Not necessarily. A number of apps can run on earlier versions of Android (ex: Android 2.0--Eclair). It's up to that particular app developer if they want to release an app that supports older Android versions. However, with the number of devices still supporting an older Android OS dwindling, it would be no surprise if a developer may no longer support an older OS.
Windows 7 is an OS for computers. But if you mean windows 7 the new phone OS then i would have to say android. There are thousands of apps you can buy (and still hundreds that are free)
