Its funny even on android forums i run into the same problem that i do at my job (warranty for at&t)....people just dont know how to use their phone
1.How often do you restart your phone
2.How much USB storage are you using
3.Do you have an external_sd card??????<------makes the difference
4.Do you take advantage of the task killer in program monitor?...ANOTHER BIG ONE
5.Is your GPS/WI-FI on even when your not using it?<--more related to battery
6.If your using apps that provide you with a task killer or battery save STOP USING IT....yeah sure they clear out memory and save battery....but they use relatively the same amount of memory/battery usage to do what they say they will do....waste of time
I have had this Exhibit II 4G for about 5 months, i Play N.O.V.A 3, Mass Effect 3, N644DROID, NDS4DROID, SuperGNES, and i have a good amount of third party apps downloaded for my personal use and i have no problems...sure a little lag here and there but its technology....its inevitable....when i get these lags i kill tasks...if that dosnt work...restart the phone....problem solved for at least another 2 weeks
Hope i helped im not trying to be a jerk or anything i just deal with people all day at my job who dont even consider certain things when their phone is acting up
