I posted a help request on the developers site, but wondered if anyone else has encountered this and how it was solved. I am using Juice Defender Plus on a Samsung Charge. I have the wifi setting on "enabled" and the following "options" 0n "auto disable". I have location "disabled". What is happening is that when I am at home my phone now uses my home wifi network just fine. However when I leave home and try to use the browser, I get the message "network not available. Please check your network and try again". When I leave the area of wifi coverage, why does JD not allow the phone to just use my Verizon data plan to work the browser? If I turn off JD, all works fine. It is only the browser that does not work. Texting and phone calls work fine. As an additional note, I really recommend this application as it has really increased my battery life noticeably. I love it and hope to be able to use it successfully.
