The base game (to access these quests) is $40 for a brand new copy. It's only $20 if you get a used copy.
These DLCs event quests are also free to download.
Still sucks they are being removed, but these were minor free 3rd party event quests to begin with.
There's an option called Screen Protector Mode that ups the sensitivity on the touch screen. That might help you hopefully?
You can plug in a mouse with the adapter that came with the phone to get around the touch screen not working temporarily to change the option.
