Picturre web designing

What is make and model of your tablet? Some cheap tablets are "disposable" and image form camera is a disaster

How large are the picturres your taking? THere may be a lag from shutter release to writing because there is a lot of information and not enough camera buffer space. try smaller images, say instead of Raw images try jpeg or change from jpeg fine to jpeg normal, etc. Try a different memory card. Believe it or not, memory cards come in different speeds also. Try one of the fastest you can afford and go to Nikon web site and research on Nikon approved memory cards. Hope this helps.

this is caused by dry capasitors on the frame inside set suggest u have it fixed
sorry cant help anymore
