My Samsung Galaxy Ace 2 soon to be two years old and yet I wouldnâ€™t do any upgrade. All features just are working well and fast enough for me since I donâ€™t play games. I got myself a new extended battery on mpj so it actually runs forever. Gimmicks will cramp my style. From what I can see my I8160 should continue to serve me until next year. How long do you think your phone(s) will last?
