One thing that comes in handy is having CLEAN RAM on tap.
When I run it on level 2 it unfreezes any lagy programs, including restarting SENSE and the phone will be more responsive.
Also I noticed that sometimes the phone is going into LOCK without going to the LOCK screen.
I figured out to touch near the upper right corner of the screen and then the LOCK screen shows and I can unlock the phone to get full access again.
A few glitches but overall I still like the Teya.
The included Media Player, Stream player, etc is also updated versus what came on my imagio. Most of FLASH is working with the current settings and the version of Opera 10 that I am using.
