Of course you won't, because there aren't any worthy Nexus phone yet. When Sony is to make the next Nexus phone, say that again.
In America, the Nexus is an important device in Google's lineup. It gives you the pure Android experience.
The Nexus made by Samsung was kind of a hit back then. It then changed to LG for the last 2 generations as the manufacturer and virtually non of us Malaysians are interested in a LG products, given their poorly managed after sales services in Malaysia. Not even the telcos dare to import more Nexus devices in these days. Due to the failure of the Nexus 4 (since LG became the manufacturer for Nexus devices)
If the Nexus device would be Sony, it will be a win win situation. I'm sure Sony will bring the game to a whole new level. Imagine a Z3 running Vanilla Android, with their build quality, and water resistant properties and subsidized price RM1499 for a high end flagship phone, it would rival the iPhone or Samsung well.
In fact, I don't think Sony has any problems in the hardware department. My biggest concern is their software department. Hence, that's why I say if this two company mix together to make one device. It would a great one. Not to mention their camera performance. Sony will be the perfect canditate for the next ultimate Nexus device.
Well, just my 2 cents anyways. Take it with a pinch of salt.
Well, after being using the Xperia Z1 Compact for so long, I didn't find any faults with its Android. So hence, no worries about its software. Google makes android software, its up to independent phone manufacturers to enhance their version of Google's Android. It is not certainly that Google's Own version of Android (you N5 fags call it pure Android) would be best for all users. Different users would have different preference. Frankly I find the OS on the N5 to plain and simple to my liking.
