Except that device is used as where your hot wallets store with very small fund for regular use, your other wallets that store your main and big funds must be very limited with applications installed from any source.
There more softwares or applications you install on a device, a more risk that it will be infected by a malicious application/ software / extension. It's safest and best in security to prevent risk from your very first practice, rather than carelessly install many things, and get troubles later.
Fund lost won't be able to get back, because no reversibility on blockchains to help you, and chance of finding the hackers, arrest them, seize their stolen funds, and compensate it for you is very small, almost zero.
As a Crypto enthusiasts, we should take and observe all security measures in protecting our asset's from scammers and hacker's because they can at all costs use any convenient trick or format to lure their victims into their web.
