samsung phone remote viewing problem

[cbr1 0]

Wondering if any one can shed any light on my continuing problem?

Ive ran an avtech dvr for two years, its fine when viewed on an apple iphone, i recently changed to a samsung, as has my father, who also uses an avtech device, the problem im having is that the samsung seems to have the power to lock up the dvr, all is fine if the phone is not used to view the cameras, ive proved this many times by sitting at home and constanly logging into my system, it will then lock up, I never have the problem whilst using a pc, my father is having the same problem

It must be something in the app or something is starting to go wrong with the dvr.
