Hi .
Sorry for this dumb question ... but I really need to know ...

If I convert any app to system app , will it work more faster ?

I meant what is the benefits of converting an app to system app ....

I use launcher 8 . When I exit from any app (specially browsers) it takes ~10s or sometimes more to load the app drawer ..
If I convert this app into a system app will it work fast ?

My device - ZTE Blade (Gen 2) & using CM 10.1 KonstaKANG

Thanks .
