I believe my ex bf hacked my cell phone. Is there anything I can do to fix this?

yes

what can be done? I believe he is reading all of my texts and emails and listening to my calls...

change your code so no one can get in to your phone,, or just have him beat up,,JK

check with your provider
get another cellular telephone
change providers
check with local authorities about local wiretapping laws
get a bigger boyfriend

lots of other things you can do, but for those you need a very strong alibi

ohkay last one is a joke, but please be very careful because some people can't take rejection very well and you could get seriously hurt if this guy loses it. godspeed, bulldog

If I thought this I would call a friend that I knew had a landline, and set up a phony conversation that would take place through text with them. Hopefully a nice sexy friend of the opposite sex... Then I would have a sexy conversation with said person with enough triggers in it to make sure if he was he would be contacting me.
Then I would report his butt.
Also it is a good idea to change passwords on everything periodically and my phone is changed bi monthly...
Because of hackers..

Could be the FBI

Or MI6 ... Or the Dutch secret service. Wait a minute... do we even have one? Yes... I think we do! Although most everything gets made redundant here due to 'budget cuts'. Believe we recently sold off our F16s.. I think the Dutch army is now 1 helicopter, 1 pilot and 1 guy to jump out of the helicopter?

Anyways, I'd contact my provider, see what they can do.

Geek here. Going for Computer Science. Change the email passwords. You can go to your apps and try and delete the ones you are not sure about. Maybe go to the app store and check my app installed and view what they are. Factory reset would wipe Everything. So if worse comes to worse that could be an option. I think the app is sheep guard, and the app hotspot shield can block him from getting your phones cache when you share a wifi signal.

really

do a factory reset to get rid of any programs installed that you may not know about and change all of your passwords

factory reset **** won't work usually if they went that far to hack usually they are running a RAT program remote something or.other they basically take control of your hardwarw

Besides a factory reset does not remove installeds apps. Just their icons. If you suspect it just remove the apps you don't use. If it is as hidden app sometimes you need to use an app to unhide those.
