Advice on selecting a new cell phone.?

I need a new one. I have used a Samsung Galaxy 5 for quite a while now. The first one was awesome. This one not so much.

I tried the Note and the reception was very poor.

So here we are. I need a phone that receives a week signal well. All the companies make bold talk about their reception but they are talking about their network not the phones ability to read the network.

The best network in our area is Verizon. I live and work in the two worst places for reception but no other company gets anything in these places.

Next, I don't do games at all.

I am a lab technician so I do load up on math apps and solution calculators and timers and Polaris Office.

I do use navigation.

I browse the internet, but no flip board or any of that news media junk.

And last but pretty darned important I take photos for work. The SG5 is the slowest thing I have ever used. In the bright sun it is impossible to see the screens so forget changing a setting.

So: excellent and fast camera, state of the art receiver, and as little bloatware as possible, it has to accept a micro SD card, and it needs to have a fairly large screen (I can not see the little ones)..

Does anyone have any thoughts on brand and model?
