Bro plz make a video on how to install package as a system app as I want to use many apps like huawei histen etc but those only work as system app Plz help me for installing huawei histen on any android or windows device because huawei histen is best audio mod in the world Thanks for the help in advance

Can we instal any package as a system package Like if we install those apps as 3rd party then simply we can do it through device package Installer so kinda it doesn't make any sense to use pc for this shit.
