just confirmed on Wikipedia, i suggest u to check once there or on any tech site u follow, it states what i mentioned above.
GPS+A-GPS is best
A-GPS fast but only when a internet connection is available
GPS slow but without a internet connection
Okay, I see now why you are confused:
- According to Wikipedia, smartphones do exist that support location services based solely on A-GPS.
- As you stated, the Lumia 630 spec sheet mentions A-GPS but not GPS. You are (understandably) misinterpreting this to mean it doesn't support the later.
However, if you carefully read the
Widipedia page you mentioned, you'll notice it partially contradicts itself on this issue.
From a very technical point of view, you are correct. Spec sheets really should list both A-GPS and GPS, but very few do. The industry has long adopted the practice of just mentioning A-GPS, which is implied to mean it also supports GPS. Simply looking at Nokia's other spec sheets already gives you a good hint. Not a single Lumia spec sheet explicitly mentions GPS support. The
Lumia 930,
Lumia 1520, and the
Lumia 925, no, none of them explicitly mention GPS support, only A-GPS. Yet, all of them include a fully functional GPS unit. The same is true for the Lumia 630. The spec sheet may only mention A-GPS, but it supports GPS too, just like the others. How do I know?
Many, many reasons. Here are just three:
- The WP hardware chassis spec mandates that every WP device include a fully functional GPS unit. OEM's may not legally build a WP device without one.
- The Lumia 630 is based on the Qualcom MSM826 SoC. Qualcomm's spec sheets and even their press release explicitly mention GPS support for that SoC!
- Websites that are geared towards the more technical minded users actually do list both GPS and A-GPS for the Lumia 630 (for example here), but like I said, sites that care that much about technical correctness are very rare. Even OEMs think that level of detail is more likely to confuse consumers then help them.
In summary, the Lumia 630 does support GPS and A-GPS, just like every other WP device ever built.
