Android is quite weak in security systems, but if you know how to maintain it, I don't think it will ever be a problem. So far I have used Elextrum and BlueWallet on Android during the use that I have done, there have never been any problems until now. There are some features that you might need to turn off if you use Android and if the use case is only a crypto wallet + Google Play, I don't think there will be a big problem.

Security must start from the way the user maintains it because hacking often occurs due to mistakes made by users and many unofficial sites are sent and then opened and in the end they succeed in hacking the Android that we use.
