Played around with my evo lte today to see if my signal was worse and speeds lower after the update( I reflashed the firmware +data profile update). I did10 test cycles using rootmetics and dBm average was -104 with average downloads of 127kbps and uploads of 188kbps. I ran an RUU back to stock shipped and ran 10 test cycles again, this time average dBm was -98 with average downloads of 527kbps and uploads of 308 kbps.
All tests were done at the same location. I also activated my S3 on my sisters line (temp) and did tests at the same time, tests were on par with the EVO lte in signal strength and speed before the update.
I ended up having a longer lunch today then scheduled, so i drove out to the site just north of town again, when my evo LTE switched towers, it showed i had good signal strength, but no 3G for about 40-45 seconds (this is after the update) lol.
I have no idea if these results are coincidence or if i have a defect evo lte. On wednesday, ill have a sprint store take a look at it (also has the light bleed issue)
