The background that DOCOMO has decided to carry out a campaign to present "pie fruit" after "Pie", a code name of Android 9 is many users who have not introduced even if the OS update is provided. It seems that many people did not know the information provided by the update. Android 8 as of the end of July last year.0, 8.As a result of the questionnaire survey conducted to those who used the model that had been upgraded to 1, about 60 % of those who introduced the OS update were aware of their own OS update. It is said that it was introduced without it. In addition, a security survey states that more than 70 % of those who have been worried about smartphone security. If you turn on the "automatic update" function (the display name varies depending on the model), the update is basically automatically updated in the middle of the night, so I think some people may not notice it unexpectedly. On the other hand, if you operate it yourself immediately after the update notification comes, you will have a firm recognition of the update. The update also has the latest security measures, so docomo recommends an OS version upgrade in terms of security enhancement. And it seems that this campaign was planned to improve the cognitive rate and want more users to update. By the way, Android has a tradition that the name of the sweets is attached as a code name for each major version of the OS. The code name of Android 9 is "Pie". The list of models to be campaigns (models planned (including provided) for Android 9 updates) are as follows.
