For those who are using iPhone and androids be careful ,their are some crypto mobile wallets on store that aren't popular or well knowned ,please do not use them ,some of this apps have keyloggers pre installed ,they will easily steal your backup phrase
Especially those named 'bitcoin wallet' like in the picture below, they are well rated and they are in different colors

Head to playstore or iOS store and type in just 'bitcoin wallet' you will see many fake bitcoin wallets popping up ,go for popular mobile wallets like coinomi ,trust ,enjin ,mycelium ,coinbase ,bitpay ,copay,bread ,jaxx or atomic wallet.
Yes keyloggers can do serious damage to us and also they can steal our bank details and steal ou money which maybe come with any apps so please watch wha are the permissions they are asking for before installing it or clicking next while installing.
