Whenever you launch an app on your smartphone, it generates data in various sections of your phone’s RAM. Those who own a phone with low RAM can’t keep multiple apps open on their phone, because of this reason only. However, if you have a Huawei P30, it won’t be a problem for you because this Android phone comes plenty of RAM space. You can smoothly run more than one app, at one time, on this phone. It features HiSilicon Kirin 980 (7 nm) chipset for best performance and smooth operation.
