Hey to all iPhone 6 plus user out that. I notice my phone after a restore only managed to get 3 dot of signal strength and I use the field test and compare it with my friends iPhone 6 and my 5s and found that the signal strength in decibal is lower than there's by -10. Eg mine (-102 decibal) my friend (-92 decibal) and that's a lot of difference so was wondering if this is normal and any other users out there experiencing the same thing?
