Hi there! I'm on the hunt for my next Xperia phone. And i'm quite excited for the new M5 here in the UK but i'm not sure if the older Z3 is better and a good steal with better specs. What would you choose between the two in particular: 1. Camera - M5 video recording has some "hissing" noise but seem a significant improvement over the M4 Aqua. I also heard the M5 camera loads bit faster but processing still seem slow; still no ability to swipe left to view photos taken (much like a vanilla Android feature) and photos on both still has this "cool" hue like in the past 2. Battery life - M5 has 2 days, Z3 slightly more? 3. Waterproofing - Z3 has the fiddly flap, the M5 has none and is more convenient. But is the M5's USB and headphone jack waterproofed as well? 4. Screen size - On my 5 years of use of Z phone the ideal/maximum size i'm comfortable with is 5.2" (Z3) but 5" seem the absolute minimum. Bigger means better? And which screen quality/resolution is better between the two? (better in outside sun and doesn't "burn" too much in terms of saving battery life. Any thoughts please?
