I have purchased a asus nexus 7 but it has some lag in features it has 1 gb ram 16 gb memory with android version loolypop there is no space for sim and memory card it has a big hanging problem.
Whenever I use it it first becomes hang for a minute then it working right but it has slow speed no rear camera front camera is good for video calling I used it for calling my friends and relative its 7 inch screen is huge the battery backup is very good thing for this tab its almost perfect but I dont suggest anyone to buy it it I s just wastage of money so dont buy it at all.
