I'll be in London and Paris at the end of June/beginning of July. I'm doing a good amount of reading/research online to get some travel tips. Frequently, I have read that you need to be careful about having your phone "nicked". For instance, I have read not to use your phone for google maps or similar because having your phone out frequently is an invitation for theft. Is this something we really need to be concerned about? I feel like using my phone to navigate is going to be very important. Plus, I plan to take A LOT of photos with my phone. Should I not do that? I'm very confused by all the advice I read to keep my phone away.
Thank you, in advance, for any insight.
