It's time to replace my Galaxy S and the Galaxy S2 looks like the logical choice. However, for all its qualities, the Galaxy S is marred by LAG, and even occasional FREEZING. Current or ex Galaxy S owners will know what I mean. I do not trust Samsung very much, as they should never have released such a poor product. I mean, these defects ruin the experience, despite all the great features. So my question is for you Galaxy S2 owners. I know that the S2 fares exceptionally well in benchmark tests, etc. Read the reviews, watched the videos. But the Galaxy S had good reviews too! In real life usage, does the Galaxy S2 REALLY cut it, without the lag and/or freeze episodes that ruined the Galaxy S experience? The S2 is the strongest according to most reviews, but I'm also considering the HTC Sensation, its most obvious competitor... my wife and my son's HTC Wildfires seem more reliable than my Galaxy S! They are smaller and do not have all the features but they do not have lag. Thank you for any comments based on real life experience!
