[Galaxy S II Original Android Development] HardCorePawn:
Known Issues

i9100 Specific

Known Issues (Build 4 as at 01/04/2014):

SDCard/Fuse Daemon issues (aka "Music Playback Bug"). On extended music play it can suddenly happen that the playback stops.

Camcorder - Zoom on 1080p mode is buggy see below for "workaround"

WiFi Direct doesn't work

General

Known Issues (Build 4 as at 01/04/2014):

LTE tile: on clean flash if the first toggle of LTE tile does not work go into settings->more->mobile networks and set one time the network mode to 3g. After this the LTE toggle will work always as expected

National data roaming: If you tick the option in settings all entries get visually disabled although they still work. Do not worry about it and just re-enter the screen again and it is corrected. As long as SlimKat supports your provider this works as intended.

Notes:

If you are running on ART, and you're having issues with an app... check this list to see whether app is known to have issues with ART.

Zoom on 1080p mode "sometimes" works... if you set camcorder to 1080p, switch to camera, change res so zoom starts working again, and then switch back to camcorder... zoom will work on 1080p :silly: However, if you turn the screen off, or close and re-open the camera, the zoom will be broken again :rolleyes: Also, once it stops working on camcorder, it'll probably stop working on camera as well until you change the resolution/picture size

4.4 mini-FAQ

Q) My recovery won't flash the 4.4 zip... aka "Status 7 error"... what do I do?

A) Get the i9100_SlimKat_4.4.2_compat_recovery zip attached below... flash it... reboot to recovery... be amazed by new TWRP recovery... then:

Wipe - Advanced - Select cache, dalvik, system (and Data if you want FULL wipe)

Install Slim ROM + Slim Gapps

Reboot

Profit!

Q) Root doesn't work!

A) From a clean build you need to enable root access for Superuser itself. This is different from some earlier versions of android (4.2 and below) in which Superuser by default had root access on a new install. To do this, go to Settings -> Developer options -> Root access. If an app attempts to request root access before Superuser itself has access, it may cause problems with that app in the future where root requests are silently denied.

Q) Developer Options? What Developer Options? I don't see that in Settings??!?

A) By default, this is conveniently hidden from view... as it does contain settings and options that can (and will) break stuff if you don't know what you're doing. If you require access to this, Settings -> About Phone... Then tap on the Build Number 7 times.

Q) How to change DPI?

A) Currently, this feature hasn't been ported... so you'll need to install Texdroider DPI from the playstore... or edit /system/build.prop and change ro.sf.lcd_density to the desired value

Q) I upgraded and lost my sim unlock, none of the unlock tools are working?

A) Unfortunately, I have nothing but Bad News™ for you :( Seems Samsung locked everything down and Google played along... Get a "proper" (aka carrier) unlock... or use older versions of Android... There is nothing we can do :(

Q) Music just randomly stops playing... and then won't work properly until reboot and/or drains battery?

A) Unfortunately, there isn't a whole lot we can do. Due to new SDCard handling and issues with FUSE, there is a strange quirk with Exynos4 devices like i9100 and n7000 where the system freaks out and dies... users have had various levels of success trying some of the following workarounds: 1. format sdcards with ExFAT (apparently can cause issues with backups and/or GPS apps??)... 2. Put all your music on internal SD...
