I have looked after me, the internal memory of my one year old Samsung ACE has become too small, the ACE 2 NFC (to date only the version can be updated with NFC on Android 4.1.2) gained. Overall, I can only report positive. Battery life is ok to accommodate the format optimized for the smartphone in every pocket (shirt, shorts etc). The display excellent in sharpness. The readability in bright conditions is better than the old ACE, but for my taste still too low. To criticize is only the striking delay in loading an app (for whatever reason). Here the old ACE was nimble. Within an app but no shocks can be determined; there everything runs smoothly. Overall, highly recommended.
