There should be supporting codec for ultra power saving mode of samsung galaxy devices not only samsung but all the other phones in which we can not use adobe app in power saving modes because at some important times we need to get information for a particular situation like in case of medical emergencies but at that point carrying such a heavy medical books will be like a drag where as its pdf simple n easy to access but if we can't use it ultra power saving mode then it will be very grave problem and apart from it unnecessary time killing apps like facebook youtube and whatsapp have supporting codec for power saving mode so i think a very important app like adobe should have a supporting codec for ultra power saving mode !!
