[Q] ROM Question topic

Hello thank you first off for the nob friendly opening, Finally!!! I'm running Slim-4.4.2.build.3-Offical-3055 Kernel Version 3.4.78-KT-SGS4-gc30c87e autobuild@slimgerrit #1 Build Number slim_jfltespr-userdebug 4.4.2 KOT49H 3055 test-keys. I hope that's what you will need to answer my question. I'm having a problem with a lot of different kinds of apps not working at all and I my Galaxy Gear will not work with it either. And suggestions will be greatly appreciated. And I'm not just completely sold on the ROM I'm using that I can not change to another one. Thank you.
