PlayStation Mobile support after Android 4.4.2. Access and re-downloads on 4.4.3 and 4.4.4 will be up to publishers. Support groups will be held every Tuesday and Thursday at your local Sony store. Ask the manager for specific times.
Sony is shifting PlayStation Mobile support resources to PS Vita and Vita TV. Given that PlayStation Mobile was an antiquated model, we'd toss in the very real possibility of PlayStation Now support being in that mix as well.
