It sure isn't customizable for me on my Razr Maxx. I am up to date on my OS and I wasn't rooted before but I am now if any of those things make a difference. Are you able to control the frequency of how fast the led lights up with Light Flow? I've tested (unrooted and rooted) out the free version and it won't change for me. No matter the frequency I change it to (slow, fast, very fast, constant, etc), it stays the same speed. Is the paid version different in that aspect also along with lighting up for more apps? I'm also having an issue where my individual contacts text color(purple) won't change from the every sms color(yellow). I haven't tested out any other options(missed call, mms) to see if those won't change either. Are they working for you on your razr? I miss my BerryBuzz!! Any help would be appreciated!! Thanks in advance
