We have already seen how it is possible to delete applications on Android by uninstalling them. But there are some apps, those called "of systemWhich are difficult to uninstall.
In fact, it must be said that when we buy a new Android phone, they come on it preinstalled an indefinite number of applications for promoting third-party applications. We will also find pre-installed Google applications. These pre-installed applications are also called bloatware o system applications. These applications are annoying not so much because they could be useless but for the following reasons:
- They consume the battery even if they are not used
- Consume system memory (RAM) and storage (ROM)
- They consume data traffic
If your phone has low RAM or ROM memory you may really need to do a cleaning between applications, precisely by deleting these pre-installed apps, without having to make use of permissions. ROOT.
Being the Android operating system developed by Google, we will find many Google applications in pre-installed form on the mobile such as Google Play Store, Google Chrome, Gmail, Hangouts, Google+ and many others. Sometimes we also find third-party apps in demo version which then ask us to buy the full version.
The moment the user loads to delete or uninstall such pre-installed apps, they may not be able to do it with the usual uninstall method because the system will refuse the operation. So how to solve the problem? Below we see two possible solutions, the first simpler to do (but it goes to disable not uninstall the pre-installed app) and the second certainly more complex but which actually eliminates these apps without the need for root permissions.
