shortcut accessibility feature-floating icon shortcut


    since buying phone at T Mobile Store I have had many issues. I will address one minor issue that I miss since I went directly to T-Mobile Store and they said the problem was the SIM card originally installed. they replaced it. Great. one feature I use and cannot access now is the shortcut accessibility where there appears a floating icon on any screen to access certain features very quickly. One being screenshots which I use often. Any advice on how I can get that accessibility or floating icon on any screen back. I will address other issues, I guess, at a tmobile store again. Thank you very much if you can help.
