Some year ago I emailed schtuck for this issue occuring since 1.6 i guess (can't remember, it was 2014). After a patch that brought us the new menu style the Gun-con keeps disconnecting. It's precise but before the patch it kept firing right, since then and to this release (09/07/2018) it doesn't work well.
Devices used: Motorola Droid 4, HTC M8, Honor 8
Whenever I use the old APK to reinstall the older version it works perfectly (as we discussed time ago).
Time Crisis setting: press to reload
Don't ask me to use "release to reload" that sucked even with real guncon.
