Upcoming Nexus Devices

This year, the expectation is that Google will launch at least one Nexus device which could be Nexus 6 and Nexus 8 or Nexus 10 tablet. But it is also possible to get all three during the release of a new Android OS version, with LG, ASUS and Samsung as likely candidates to manufacture the next-generation Nexus line. However, others hope HTC and Sony could co-create with Google for 2014.

Based on the plan posted at the Google I/O Session page, below are some clues revealing new stuff coming on next-generation Nexus line:

1. New Bluetooth technology: Android 4.3 features Bluetooth Low Energy and Smart

2. New improvements on gaming experience via Google Play Store: Nexus-exclusive gaming section?

3. More useful Daydream apps

4. Enhancements on graphics performance: More supported GPU or new OpenGL ES version?

5. Updates on the cloud storage: Android Device Manager appeared on Android KitKat

6. Audio improvements focus: Nexus 5 features low-powered music playback

7. New accessibility features: Better Blind and Low-Vision supports

9. TV support may end up on new Nexus devices: Chromecast already servicing Android KitKat
