This phone is really a beast network speed is awesome, calling quality best, smooth running, build quality good but slippery so have handled with care, I had install several games like injustice, motal combat, asphalt 8 done multi tasking among all these 3 games it was flawless, fingerprint sensor works perfectly even u scanned upside down, battery life is good while playing games multi tasking it last about 10 to 15 hours and on normal usage it works 2 days sufficient for me though.
