If anyone has experience managing wallets on Android, tell me if your funds have disappeared some time?
my fund has never disappeared in my wallet before, as a matter of fact i am still using it uptill date. fund can only disappear in a wallet if it is hacked.
Has Android system spying for private keys?
yes android with spyware or malware virus can be used as a tool to get a sensitive information from your android device and prompt to hack. for example if you click on a site that promise to do some airdrop or some promotional offer and you decide to sign in with your wallet by imputing your private key, then you wallet can be hack.
I mean on a pure Android without any installed apps excepting crypto wallets + google play
if your device is affected by malware virus online, you don't need to have app for it to work because it has a total control or full access of your phone
