I am running 4.04 on the razr maxx, and I hate to say it, it aint much better - it may be worse even...
I think its not so much a radio issue as it is power. The motorola verizon version of ICS for the maxx seems geared to conserve power, why?
Well, after making adjustments to imporve the experience, the battery on the maxx seems to drain quicker than GB...
Can anyone confirm this? BTW - I am not overclocking or anything like that.. just relieving the unit of animations etc...
As far as 4g, well, ok, 4g is fast, under the right conditions, meaning if nothing is disturbing the signal. It seemed that when I had just a 3g phone, it was pretty solid, no noticable interruptions - with exception of true dead spots.
4g seems weak - or can be interupted by any change in environment...
