FP3 better than FP2

Recently I have quite a number of problems with my FP2. Either WiFi is not working (switching of by itself) or none of the two SIM cards are recognized. Or an incoming call is not displayed, or there is no sound on an incoming call. Battery life is ok but sketchy. I"m about to through out the FP2 to a E-landfill as it is clearly not a very useful phone. (the FP2 have a usable life of three years)
Is the FP3 any better? What was improved? can I expect any of the troubles I have with the FP2? Is there an estimated on how long I can use a FP3 reliably? Landfilling it within two years does not seem to be really green. A Sony would last longer but might be less “green”.

A post was merged into an existing topic: Is the FP3 significantly better than the FP2?
