I do wonder how they manage to get such wallets officially in the playstore. Doesn't that require a very official procedure?
While Google probably checks some of the submitted apps manually, huge majority of verifications are done automatically and that system obviously can't detect fake apps efficiently. Add on that it costs only $25 to submit an app on Play Store so no wonder that is swarmed with fake versions of popular crypto wallets. They covered their ass with TOS in which is stated that they are not responsible for any damage caused by apps not developed by them so why spend more money to make platform safer? :p
On the other hand, Apple is doing much better job when it comes to detection of fake apps; verification is longer therefore more thorough and app submission cost is higher (you have to pay $99 to be part of Apple Developer Program in order to be able submitting apps) so its not a popular choice for scammers.
If you're new and don't know what you're looking for (or looking at), it's nearly impossible to tell if something is genuine in the Google Play store unless someone's already dropped a warning feedback or something.
Yep, they are perfectly aware of the constant influx of complete newbs and that's their target audience. Huge majority of those people are used to getting all their apps through Play Store so they won't think twice whether crypto wallet is legit or not. Worst of all, looks like Google doesn't care much about the issue at all as problem is not new and it keeps escalating.
