My phone keeps popping up with a notification staring USB power supply. When I click it....if I can click it soon enough, before the option goes away to switch my power supply. I have selected every option available and selected always. I think I am supposed to have it set to charge to USB port? I don't know how to fix this problem. I have Verizon and was on the phone with them for over an hour. I did a factory reset, I deleted recent apps I have downloaded and I took the battery out hoping it would correct this issue. This started last night after I unplugged my phone from my charger. My charger is plugged into my regular wall outlet. I do have a new computer, however I have not used it yet. I have not plugged it into any USB ports at all. The only way I have ever charged my phone is through my charger and plugged into my wall outlet. I am so frustrated with this. I have a LG G5 phone and have had this phone since Aug. 2016. I want to correct this issue, I guess my only other option would be to see if I can exchange or return my phone to the manufacturer for a new or replacement phone. The weird thing about this irritating notification is that it will keep popping up for 5 minutes or so and then stops doing this for about 10-30 minutes. I would appreciate any information or solutions anyone can offer! Thank you for any and all responses to this issue!
