We saw something very similar happen in Nexus 4 too. Remember, when Google subtly added a padding at the bottom of it’s Nexus 4 after several reports hit the market that the device was shattering from the backside. And something very similar has happened with the Nexus 5 too. There have been reports that the newer versions of Nexus 5 are seeing some hardware upgrades. Although subtle, these are actually done to eradicate some of the complains that the users generally have had with the Nexus 5.
The speaker grille diameters have been increased ever so slightly which, according to the report have resulted a massive improvement in the audio output. Plenty of users had outraged about the poor quality of the loudspeaker of the Nexus 5 and the Camera. While, the camera has actually been improved with the latest Android 4.4.2 update, these hardware improvements mean that there is nothing really wrong with the Nexus 5 currently.
Not just this much, the Volume Rockers and Power On/ Off buttons have been made more sturdy and the SIM tray also flushes with the body really well meaning there is no creakiness and the hardware actually feels premium and solid, more so than it did. However, this does raise the question that the early adopters have paid a fairly heavy price for their enthusiasm.
