I personally save bitcoin on my phone, the safety is not 100% that these coins will not be touched every by anyone, but even if you store on the phone try to ask for 2FA, lock the screen, lock the apps with an additional password or mazelock
yeah save bitcoin wallet phone is basically similar to the store in the wallet in general. but it may be more easily stolen when others people borrow your cell. therefore you should add some authentication such as passwords or other authy. it will make your bitcoin safe in the phone
For me i dont use 2FA i find it hassle when im trying to login my wallet, because i beleive 2fa can be bypass if your email is being hack, it really matters on wallet holder on how he makes his wallet safer,
Use 2FA and a gmail account with a phone number added to it. i use 2fa for better security and sleep freely.
