Those who are downloaded from the Google Play Store are safe. I know that there were a few incidents with some app even from Google's official store, however generally speaking if you only download from there, you should be fine.Have you had problems with smartphone apps? Which ones have security risks? Which ones are safe?
Me, bit agree to Koroke SanI downloaded many apps from google play store & some of apps are bundled with pup coz ESET alerted me. You can't even say that apps which u downloaded are infected with pup or not until u installed a good AV who is capable of detecting pup. Downloading apps only from google play store is safe, u won't catch malware but u can catch pup so having a light AV who is capable of detecting & removing pup is a good step.
I'll do it as you did, hope won't get any problemsYou won't have any problems with Android apps installed from Google Play if you carefully inspect all the apps permissions, the number of downloads and the trustness of the developer.
Personally, I've never had any problems with Android apps.
