My Lg G4 cannot keep calls in my apartment. I can be perfectly fine on a call, tilt my head or take one step and I suddenly start hearing "Hello?? Are you there? I can't hear you!" I purchased a Wilson cell phone booster in December and it did nothing to boost the signal, so I returned it. My apartment building is one of those concrete block construction, so I know that can inhibit signal, but within inches(?!?) doesn't make much sense. My boyfriend has a Droid Turbo and has never had these problems. My old Samsung S3 didn't have these issues either. I'm not finding much on this topic on the interwebs... Do I have a lemon? Is there something I can do to improve the call strength? Do I have to buy a cordless phone for a landline to use at home??
