Hi Oliver,

I found a video teardown that shows the removal of the charging port as part of the process.

Samsung Galaxy Tab S7 11" SM-T870 / SM-T875 Full Disassembly Teardown Guide. - YouTube

Follow the guide through the removal of the screen to about 2:22 into the video, then skip the section on removing the midframe and jump to about 3:35 where it shows the removal of the charging port.

Comparing the video to the Tab S7+, it does appear there are significant differences in the way they come apart, most notably in the fact that the S7+'s midframe covers the charging port so it has to be removed, while the S7 doesn't. On the S7+, the guide shows unplugging the LCD from the motherboard, while the S7 video shows that you can unplug the display from the LCD itself.

Hope this helps; let us know how it goes!
