Hey everyone I recently got my iPhone replaced at the genius bar and the next day as I was using it at home and school, I noticed that my reception bars and wifi bars were not as "high" as they usually are. I also compared my 4S to my dad's... I left them both in the same place and periodically checked on them and noticed that I always had one bar less than him - both on wifi and reception. We are both using the same carrier. This has never been a problem for me as on my previous phone I always had full wifi signal and full reception at home... I tried resetting my network settings and doing a hard reset AND restoring my phone, but it seems like my wifi and reception still is not as good as my dads. Any ideas? Should I bring this phone back to the genius bar? Thanks in advance!
