My girlfriend asks me to switch phone with me and I think its a good idea for every relationship.

Switch phones with your partner for a period of a week? That's a long time!

I understand if it's here and there, but a week?

Also, something to keep in mind, I don't think that you both need to 'switch' phones, but rather let each other use the others phone when they wish.

e.g if I asked my girlfriend a question regarding what the time is, or to search something in Google and she said 'use my phone' - I know she has absolutely nothing to hide because she's allowing me to go onto her phone, does that make sense?

But if she takes her phone EVERYWHERE and is very protective, then I know something is up.

I don't think you need to have an occasion where you bot switch and purposely try and find things, rather just be more flexible when it comes to using each other's phones.

I know a guy and he's a friend of mine that is good at it. I mean good when it comes to hiding something on his phone and even his partner will check it all day, she won't find anything like a trace of doing something cheating but the guy really does. And he told me he was caught just once and that is the last when he starts using one of those apps that hides online activities and deletes all history- I believe it works like incognito tab using chrome but I'm not pretty sure what is the app's name. He was too techy that even our company wifi, he can gain access into it by cracking lot of codes and I do also benefit because he let me get in. Idk but he's good at it. That's the reason why I dont like to introduce him to my friends because he might cheat to all of em' Well yeah this guy needs a phone switch for a week LOL

This is the first time I've heard of switching phones maybe to bolster the trust for each other. Although there's nothing wrong with that but I guess that's preposterous. If someone is cheating, he can be using another phone for that matter. I know of some couples whose password for their social media accounts are known to each other so they can check on it if they want. But again, that's not a safeguard as proof of fidelity. Trust is earned and not bought, that's a saying that applies to the phone swapping.

Im so agree to this switching phone idea it will be like sharing things with your phone that ill be cool each of one that is really nice. But ofcourse it will depends to the person.
