I had a Hp 7 voice tablet which I had bought from online. Its camera is not good, the front camera is just vga and the rear camera is 5 mp. Neither you can do video calling using this tablet which was my main aim nor you can click fine snaps using the rear camera.
Its internal memory is 8 gb in which 4 GB is allowed for user. Could have been more for this price point tablets. It runs on android Kitkat. No updates in this tablets. Only a pros I could see is it has a usb internet tethering facility. Otherwise you can go for many other products for your purchase.
