Thanks, went ahead and disabled, even though it says recommended to leave enabled? So will call quality actually be better even in a weak LTE spot? Not really sure I understand all that. Thanks.
I have an LGV40 with this exact same issue. I researched it a little while ago, but let the issue slide when I thought I'd be upgrading sooner. Unfortunately I had to push back my upgrade a little while longer, and now this 3g issue is driving me nuts. I thought I remember reading it was an issue with android OS, but I cannot confirm as I cannot find the source material.
Would like to start by taking a look at the area. Provide us the nearest cross streets and ZIP code. Are you having this issue in one or multiple locations? Do you know if there's any other Sprint customers in this area with the same issue? Have you always had this issue with the phone?
I get what you're saying, you may think that the issue with your device may be resolved with a software update, but keep in mind that your girlfriend's phone is a Samsung Galaxy Note 9, and yours is a LG V40 and there's also other factors that can affect your device connectivity to 4G. I don't know what troubleshooting steps you have performed to the device and this is the reason why I need to start from the beginning. I have all the disposition to assist you, however for this, will also need your help and cooperation. If you change your mind, and would like to continue to be assisted, let me know.
