rooted s3 not getting 4g as much as stock rom
I flashed my stock rom to hyperdrive rom. My stock s3 got 4G all day at my house. After i flashed it to a different rom, I mainly get 3G, sometimes it will get 4g (says h+). All my phones i owned previously i would have 4G all day at my house. My mom's and sisters S3 (which are stock) have 4G ALL DAY. My question is what did i screw up when i flashed this new rom?
also I have t-mobile and i live near SF california
