@ElAguila64 You don't need a PC to take screenshots, i have an older Android device and i have to hold down the off button and volume down buttons simultaneously to take a screenshot.
The screenshots allowed for posting on this forum are less than 3.2mb in which case i go into my gallery, hold my phone up in portrait mode (the screenshot should turn around and shrink), screenshot that image then crop it to fit.
I post a lot of strategies in the mini forums using this method.
I know that with the EA HELP complaints sreenshots you are allowed several (instead of 3 on the forum) and they are also allowed to be larger.
Hope this helps, here is a page from my own google playstore purchase history which is the kind of thing they need to see to remedy your complaint.
Most tablets also have the ability to take screenshots as well, just do a google search for how to do it for your specific device.
