The signs were ominous, Sony had already ended support for PlayStation Mobile (PSM) on Android devices and now Sony has announced that it will be closing PSM for good on 10 September 2015.
Sony has said that distribution of content will end after 15 July 2015, whilst the ability to download purchased content will be discontinued after 10 September 2015. On this same date, the “PlayStation®Mobile for Android” app will also be unavailable for download.
You will still be able to play the content you have downloaded after 10 September, but you will have to follow the steps below to activate your device. Remember, after 10 September 2015 you will not be able to re-download purchased content so you must make sure you download any games you want to keep before then. Also, devices that are not authenticated before 10 September will not be able to access your PSM content (even if you have downloaded it).
Steps on activating your device:
For PS Vita users:
You will need to complete the device activation process by performing the steps below between March 10, 2015, and September 10, 2015:
Go to [Settings] > [PSN?] > [System Activation] > [PlayStation Mobile] > [Activate] > [OK].
For PlayStation®Certified device users:
You will need to open up the PSM app and launch any purchased PSM content between April 10, 2015 and September 10, 2015 to complete the content authentication process.
