Same here. I don't really trust new developed apps to be downloaded in my mobile phone as there might be some malware or something like that although I don't have any important files or anything that can compromise my wallet because I have my old phone that is no longer connected to the internet for too long and only use for sending funds then go offline. I also look for feedback from users if there's any negative feedback to their app before downloading.
Alright, you don't trust any new apps, but you trust old apps. Then the real problem stands here: it seems that malware is embedded into copy apps. It means you may think that's the real app, but you don't know it's a copy or clone with embedded malware. This is the most dangerous attempt to confuse users. Let's say you are looking to download a wallet app; it would be Electrum. Usually we trust Electrum since we are familiar with it, but hackers could make the same copy, maybe with little change on logo or not, but they could push the malware through that fake app.
Google Play Store should censor and filter strongly to prevent fake apps and malware. If constantly happens this kind of hacking issues then likely they will lost their users. People who really care about their device and funds would start avoiding using the Google Play Store. But from our end, we need to be careful and make sure they're the real apps. Check downloads, review though it could be purchased online, and check developer information as well. And for our crypto funds, it should be handled through a hardware wallet.
