On Saturday i upgraded to 2.3.3 from Rogers. UNFREAKIN BELIEVABLE.
My battery life on 2.2, used to be at 25-0% by end of day, now im looking at about 70-60% based on usage (still heavy) Wifi works perfectly fine, GPS works better, Googlemaps comes up quicker and is now more accurate.
Text messaging:
+Alerts dissapear after quick view of message
-keyboard not included with Gingerbread update (should be automatic, downloaded an app for this)
-No visual difference between 2.2, and 2.3
Voice:
+Calls are far more clear
+2.3 dials WAY quicker then 2.2
+light sensor works properly on calls and doesnt accidentially turn the phone on in the middle of a call.
Apps:
Ive had to download a couple, right now, im using ADW with a Honeycomb lookalike (works great, and i love the main screen rotation!)
All apps are compatible, not a single crashing issue so far
**BEST OF ALL** FACEBOOK NOW CLOSES AT REQUEST, AND DOESNT EAT YOUR BATTERY!!!!
I have to say, this eliminated just about every concern and issue i had with the original firmware (2.2). Good job Rogers & Samsung!
