    Question Stuck on 3G after Jelly Bean upgrade!

    I frequently used the app Phone Info on my Galaxy S3 to switch to 3G when I needed to save battery life. On Friday I had the phone set to CDMA Auto (PRL) and was connected to WiFi. I downloaded and installed the Jelly Bean update only to realize a day later that my phone was still on 3G. I launched Phone Info to enable LTE/CDMA/EvDo and then closed the app to continue my web browsing, but 3G was still enabled. I closed Phone Info from the task manager then launched it again to find that the CDMA Auto (PRL) option was selected again. No matter how many times I select the LTE network, the phone simply won't connect. The 3G connection never goes away, either, no it's like it's not even trying. Is this something that is going to require a factory reset, because I am really trying to avoid that.

    A factory reset is what I'd do, even though, like you, I'd hate to have to do all that work.

    I had the same exact issue so I went into settings and mobile networks and changed it in there. It worked perfectly.

    The phone won't enable LTE unless you select the LTE/CDMA option under Settings/More settings/Mobile network.

    So, use Phone Info to put the phone in 3G, but use settings to switch back to LTE (no need to change the settings using Phone Info).

    I was having a similar issue. First mine was stuck on GLOBAL which seemed to draining the battery even when I was charging it. Then it was somehow stuck on CDMA Auto (PRL). I found the PREFERRED NETWORK MODE setting { Settings >>More settings >>Mobile Networks >> Network mode} and switched it to LTE/CDMA and the issue appears resolved now.

    Thank you so much!!! :-)


    I about had a heart attack over the past hour thinking my phone was ruined.

    I guess the phone info app is useless with jelly bean
