s7 says downloading do not turn off target

[Adamrwsc]

My s7 went dead overnight. I woke up this morning and plugged it in and got this blue screen with the download do not turn off target on the screen. It also seems to have tech specs in the upper left hand corner. I have tried holding the main button and power button at the same time to reboot it. It works and the phone starts up with 1-2% battery and I have tried multiple times to get into the settings to do a factory reset but the phone dies before I get close. I have family photos on my phone that are not backed up I would really appreciate some advice! Thank you so much!

Also I should have mentioned that I have one of those theme apps installed on my phone. One time while I did a reset ithe said something along the lines of moisture detected in charging port. While it's on it basically looks like the phones not charging even tho it's plugged in.
