HTC One M8 - I got myself an Xperia Z3 right after it's launch in India - got swayed by the bright display, dust proof, clarity and lag-free gaming. It turned out to be a different game altogether when I started using it - the User interface is very dull and you will get bugged looking at it and using it on a daily basis. Loads of camera features and excellent quality as well, but you won't take pics everyday, will you? When it got to playing games, about around one hour of play, my cell phone started heating up! And yes, I bought myself the purple coloured model, looked good to hold but not that great. Battery life was pretty good. After around a month or so, I found that the price had dropped and I got bored of using the cell phone!! My brother uses a S5 - has features like pulse reading, stress monitor, etc. But a very dull phone, again. Same old looks - the typical one Samsung offers. I dont like the sound of it's speakers - too loud but unclear. Android Central, Tech Radar, GSM arena and many videos on Youtube were highlighting HTC One M8 at their prime then - I decided to sell off my Z3 (a a very discounted price - didn't get a good deal) and bought one HTC One M8 (Gunmetal grey). This one is for the connoisseurs - the feel, the look, the built quality; everything. Lovely UI, amazingly fast (even more than the Z3, which used to slow down a bit on opening multiple programs together), no heating up problems, no lags for high end games like MC4, Asphalt 8. Yes, the camera is a bit 'bad' but the eye update and apps like Retrica and the in built editor does the job - like I said I dont click pics everyday. The battery drains a bit fast (likely around 18 hours after heavy use) - use the Stamina option to save it. Messaging, calling, setting up of icons, placing them and looking at them at times gives me goose bumps that yes, it is a 'good phone' to hold and to use! Lastly it's USP - sound quality - probably a 20 out of a 10 - have tested and used almost every flagship phone - no other phone can beat the quality HTC One M8 offers - both the external speakers and as well as the earphone plugged in mode!! HTC One M8 - my say!
