It have all the Google apps including Drive, hangout, keep, chrome, play music, play store etc. And even better cause it is operated with colorOS 3.0 which gives some built in apps so that you no need to download clean master, weather apps or launchers. In my opinion it's iPhone iOS like launcher is so comfortable and way better than touchwiz UI of Samsung. So I'd say OPPO A37 is better than Samsung smartphones of that price range.
You can swipe your 3 fingers cross the screen to take screenshot if this feature is turned on from gesture settings. Or just like most of the smartphones you can just hold ( power button + volume down button) at once to take screenshots.
