so i have a situation...is it possible for someone to gain access to my s9+ to view texts etc...can this be done without previous phone access to plant spyware, apps or root of any kind, can this be done with just a phone number
In my opinion it's very rare for a phone to be hacked / compromised @ivang84
I would think an unscrupulous person would need to have hands On with the phone to add tracking etc to it.
Also risks are increased if a person decides to side load apps etc via Apk Files.
If your concerned that the security of the phone has been compromised then if this was my situation I'd take the phone to a Samsung Experience Store or Samsung Service Centre to be checked and firmware flashed.
