Red mi note 4. 4gb ram, 5mp front camera, with 5.5 inches diplay, 2.5D curve screen it is a best mobile to get with in rupees 12999, but main diadvantage is camera. Its back cam is worst and cant even get clear pic I think so it is not equal to 13mp camera , if we use the cam inthis mobile in during night we cant even see the face clearly and its front cam is better in lighting we can change the modes also. I am not satify with this redmi note 4 camera which is in this mobile. And comming to ram it has been working very slow when I start my moblie fr the first time the speed of the ram is 2.5 but after downloading apps in the mobile it had readuced to 1.7-2.0gb ram and the mobile will hang up if used it fr mobile time most of the social websites will be getting hanged it will say that unfortunatly the website had stop we cant do anything in that moment same the sittution will be arrissed in 2gb ram mobiles its better to buy 2gb ram mobile rather than 4gb ram mobile. If we think that its common to all mobiles at least it must run with 2.5gb ram I think so my tought is correct. And I think so this mobile is not suitable based on given features.And comming back to cam it shows the location where we took the pic time, date, location and comming to storage the pic may consume the space of 2-4.5 mb thats what I had got captured of my pic in this mobile but we can satifed with the pic if zoom it we cant even imagin that the pic will be like that we may be unsatified and get insulted when we r in public. And comming to security purpose we can hide the pics from the gallery but cant hide whole album in it as a folder after we pressing the hide button of the folder the folder may hide some time and sometime it may not. After hideing if we check in hidden album we cant find that album we get anger some people may get nervesed they lost their important pic present in that folder so u must hide ur pics by selceting one to many then hide them the hidden pics will be opened after drawing pattren and they will be based on date, size it will be not be saved as different folders. So I request u not to buy this mobile if u want nice camera and speed working of mobile based on ram . But security purpose its the best mobile we can trace the mobile if we lost. Thats what I want to say it has worst camera and hagging of mobile
