After installing Paranoid Android 3.15-L13N ROM (4.2.2 Jellybean) on Galaxy S3 SGH-T999 it shows 3G instead of 4G. Used Speedtest and got top speed of 23 mps. On T-Mobile Rom I got 25 mps. Not a big deal but was suprized to see 3rd generation when I know 4g is better. Anyone know why this happened? I like Paranoid Android much better except for this glitch.
