I kall N4 is not over all right decision to bit or purchase because there are many problems from this tab they are this tab’s resolution is very low brightness and it is dum, dim and also not bright. The contrast of this tab is not so fine it is not good feels like it affects our actual Eyes. The battery is not made up of for long life it’s drains down quickly no matter how many you keep charging within a day the tab becomes very heat due it’s heavy usage the battery will not pickup even for a single day. The apps will run slowly usually there is slow processing of the tab. The games also will run very slowly and sometimes it may won’t work at all or unable to install its program.
