If the author didn't bother to use the menu, about feature it's too likely to be some spyware/malware.
Anything more to share such as it's Manga pictures?
First, apologies - I did try to search...
I loaded an app, which was an encyclopedic overview of 16th Century art: it is called ART Vol 1. At the time I downloaded it (not understanding the phenomenal memory of my smart phone) I didn't download the C17th or C18th 'volumes'
I am trying to track these down - but despite phone searching, and marketandroid searches, I cannot find this app. Either - can anybody suggest how I can ask the phone who published this app, or (even better!) direct me to it? Thanks in advance for any assistance.
