​Would go with the G5. About £120 cheaper if you sell the lg cam plus. G5 has a better camera, modular feature, removable battery, Less bloatware now, faster finger print scanner, IR blaster and a few more things but both phones are very similar when it comes to specs and you cant go wrong with either. Considering the price, the G5 is the one I went with.

LG G5 or Galaxy S7 ? tough choice to make (Better camera vs Better Build)... Such deals drift me towards G5...

code doesn't work on sale items

​still can't get it to work for me :disappointed: but well done you got good deal

If you also take into account their residual value, I'd go with the S7.

Which colour looks the most stylish?

Code doesn't work for me either. I just made a new account first time and wanted to pay in full by paypal.

IMHO this phone doesn't look stylish in any colour unless you have a case on it:

Does an S6 still sell for much more than a G4? Didn't think it did. This is still a few quid more than an S7 via Very anyway, and that's without selling the Cam Plus privately.
