[Q] Problems with AOSP ROMs on my SGH-i337m
First off, just want to put out there that I'm not exactly a techie so I'm not too fluent with this stuff (but just smart enough to root and flash, haha).
Anyway, I've flashed Cyanogenmod, SlimBean, BeanStalk, ParanoidAndroid, and LiquidSmooth (currently) but for each, I have been experiencing problems. Three problems, to be exact:
1. My vibration is MUCH lower than it was on TouchWiz, and I've seen my friend's S3, where his vibration is strong. Yes, I have tried increasing the vibration in each of these ROMs (past the 'recommended 75%')
2. Brightness sliders and laggy and slow to respond. I can't seem to drag the slider easily; it always lags and takes time to move where I want it to.
3. LTE does not work. I've tried turning the LTE switch on, but I never get it, or I just simply cannot connect to any band. The highest I've gotten is HSPA+ and I used to get LTE on TouchWiz...
