I’ve been using crypto wallets on Android phones for several years. I’ve never had any issues with my funds. You just need to make sure to download the wallet from an official source. Also never connect your wallet to random sites or fall for tempting offers, hackers can gain access to your wallet and steal your funds.
If you follow the rules, you will be safe, especially when you download the wallet from the official source and not a clone one. But one thing which makes other wallets safer from mobile phone wallets is when you have your wallet connected to a device you use on a daily basis to shuffle round the internet, you can never be too sure of which link you are clicking on from search which you don't plan to, especially when one is not using an ad blocker; you can get yourself exposed unknowingly.
