Samsung is good in mobile and gadgets but my experience for samsung tab 4 is not good or upto the mark.
This one is my father gift so I am loving it that is why after 2 yrs also I have this with me but the features is bit not good and few features are somewhere good also.
If I talk about battery life and battery backup this is most disappointing thing the backup is too low and as being 2 yr old now what I see is when the battery is about 10% it get directly switch off without getting lower than 10% this problem occurred few month back this was not the issue when the tab was new.
Apart from that its good to read online pdf and make notes.
