The issues i have with 3 N4's and 2 N5's are that even if i have all signal bars showing,at times i can not make a call or text etc and it ends without ringing,several times.I have changed the sim card about 3 times,i've turned the phone off and back on in different ways,i've contacted my provider.
Yes i did take the back off this phone in desperation to try to find something i could do to make it work.It's the only phone i've ever taken the back off.
The antenna is pushed onto a small nipple each end if my poor eye sight is correct.Would soldering these ends on make any difference either good or bad ?.
As i mentioned earlier i love the vanilla android Nexus phones so if i could get it working like every other make of phone i've had i would be over the moon with it.
