How do I clear our memory on an Android device?

Are there any ways of being able to transfer apps from phone memory to the external memory in an Android device?

• Rooting a device disables its warranty right? So, suggestions apart from this would be helpful. Also, why exactly is one unable to transfer apps directly to the external memory?

• Answer:

  Well, I would say if you are running JellyBean 4.2+ Android version then transferring of application from the internal memory to the external memory is possible without rooting your device but if you are on KitKat then again its disabled by the developer and the good news is if you are running Lollipop then you have the power to do that ! So, I would say it all depends over the Android version you are running if you are running KitKat and trying to move application from the internal memory to external then its not possible until or unless you root your device.
