Then what else do you trust?
For getting free apps i use only playstore
And for free paid apps, i use apkgalaxy[dot]com and blackmart(but i don't trust it much since it gives vulnerable apps)
Why not try to use Aptoide?
Sent from my GT-I8262 using XDA Premium 4 mobile app
Have already tried it. It doesn't even find the apps that i want.
Aptoide and Blackmart doesn't provide latest version of apps.
