On a Samsung galaxy s20 fe it's not so great. When you click the back button it does not go back to the previous page, it will take you to your cart or back to the main menu or somewhere else you've been but not the previous page. Also if you leave the app to say answer a call it does not hold your spot for more than a couple seconds. The keyboard covers anything your typing & you can't slide the screen up. There is also a fair amount of word overlapping.2 stars because it's better than nothing
