What happens to the phone after upgrading (over the air) version of android? Did the reset to the factory settings occur and did the data (applications, etc.) installed in the internal memory of the device be erased? Or everything remains as it was before the update?

PS I apologize perhaps I ask the question in the wrong place, so please do not stebatsya over this.

  • With the official update by air, no changes in the installed applications, settings, and so on. no trouble. Everything will remain, as it was before the update, it is not a flashing, but an update. - pavlofff
  • Trouble is possible if you poked around in the system and rearranged the data of your applications in the system directories, for example, under the root. Then they can wipe, or in general the update will not work, you will have to restore the factory image (tested by your own experience). - Jenssen
  • Thank you for the answers, I will keep in mind. - Constantine Shibaev
