I AM USING THIS PHONE FROM PAST 6 MONTHS AND I NEVER NOTICE ANY TYPE OF LAG. BATTERY CHARGING SPEED IS BLAZING FAST. CAMERA PERFORMANCE ALSO GOOD AT THIS PRICE POINT.I THINK SPEAKER VOLUME LITTLE BIT LOW. FINGERPRINT ALSO WORK VERY QUICK. PHONE CAN ALSO UPGRADABLE TO LATEST ANDROID NOUGAT.
THIS PHONE LOOK SOLID AND BUILD QUALITY LIKE A TANK. THIS PHONE IS BEST FOR GAMERS. I THINK IT IS TRUE VALUE FOR MONEY.
