This product is very bad .when I first use this product karbon runs smoothly, after some week .Then after some week it begin to hang when I add more app , its Ram can effort app it only cal effort less than ten apps only.Then all app are not running smoothly its battery power runs long lasting.If charge u will charge its full then its only runs for only 1 hrs.I have to carry charge with me all the time .Its camera is not perfect we can't take clear selfie
