I don’t think that is a reasonable statement
a) the OP doesn’t even most most people let alone those with an FP3
b) I imagine that 90% of the authors hear are complainers and most buyer of the FP3 are not voiced here.
c) I have three in the family with no such issue with signal, though there was a similar issue for a while, but I have had that occasional on Nokia and Samsung
Note that the FP3 is not available but if you are really interested in the FP3+ there is one on sale today on the forum for an very low price.
