Hi all. This is my second question in this forum. I have a Galaxy S3 that has been retired from active use as a phone. However it has all of my birding ID apps on it and I would much rather have it in my pocket when out in the field/woods than my S7. My problem is that even with WiFi off and the phone in airplane mode it randomly will start searching for a network. Is there something under settings that I am missing? Thanks in advance.
