https://community.sony.si/t5/xperia-archive/xperia-p-week-signal/m-p/3411612#M498625 <P>I bought a secondhand Xperia P, but the average signal strength it receives is -90bpm, and keeps on disconnecting when using 3G network. The interesting thing is that I have an another cellphone that gives proper signal strength at the same location with the same cellular network.<BR />beside that I observed that when I'm outta home, I guess that in air pressure it can't catch any signals. It a lot when I'm on the roof because there air is high.</P> Fri, 17 Jul 2015 18:11:17 GMT Usmansakhi 2015-07-17T18:11:17Z https://community.sony.si/t5/xperia-archive/xperia-p-week-signal/m-p/3411612#M498625 <P>I bought a secondhand Xperia P, but the average signal strength it receives is -90bpm, and keeps on disconnecting when using 3G network.
