Recently, there was a fake Trezor wallet app in Play Store,

Fortunately, it was already taken down.
SatoshiLabs also confirmed that it's not from them.
https://www.welivesecurity.com/2019/05/23/fake-cryptocurrency-apps-google-play-bitcoin/The app masquerading as a mobile wallet for Trezor was uploaded to Google Play on May 1, 2019 under the developer name “Trezor Inc.”, as seen in Figure 1. Overall, the app’s page on Google Play appeared trustworthy – the app name, developer name, app category, app description and images all seem legitimate at first glance. At the time of our analysis, the fake app even came up as the second result when searching for “Trezor” on Google Play, right after Trezor’s official app.
The app claims it lets its users create wallets for various cryptocurrencies. However, its actual purpose is to trick users into transferring cryptocurrency into the attackers’ wallets – a classic case of what we named wallet address scams in our previous research of cryptocurrency-targeting malware.
How this works is that the app pretends to generate a unique wallet address where users can transfer their coins. In reality, this address belongs to the attackers’ wallet, as only they have the private key necessary for accessing the funds. The attackers have one wallet for each supported cryptocurrency – 13 wallets altogether – and all victims with any specific targeted cryptocurrency are given the same wallet address.
Again, friendly and gentle remainder not to simply trust anything you see in Google Play's Store or Apple App Store, specially regarding crypto wallets.
