Well, I reset to factory again...and redownloaded each app one at a time this time....every once in awhile some app may be slow to respond but so far its inproved a lot..i'd hate to take it back...Staples....Also the darn unit was packed so tightly i actually wound up cutting the box open to get it out..Ok so that sounds like a hardware defect I'm sorry to say I might try android 4.1 and see if that helps anything if it doesn't send it back you've got a defective unit also make suee to relock the bootloader with 'fastboot oem lock' before you send it back
