You really don't understand how technology works, do you? Lol its because the 730 has an AMOLED display and Glance + AMOLED would probably end up with a lot of burn in on screens.
Nope, Glance moves around, if anything, AMOLED is best suited for Glance, being a feature on previous Nokia's and AMOLED devices like the 925 and 820.
Nicely said, quite true....my l625 doesn't have it, however my bros 620 has it...! Weird MSFT! Weird Windows Phone!
The 625 has a lower quality display. If you notice, it isn't ClearBlack like the 620 - more like the 520.
they'll sell you the "hardware limitation" bull****, for sure. the reality? chances are its just....MARKETING
you see? glance can really be limited by hardware, that's a fact. but alot of phones don't have it due to marketing strategies and extracosts(which i dont think they are so much, what? 5 extra bucks for iterating it from other phones?)
let's look in 5xx family. 520 has it, 530 nope (but no surprise, since that phone is a flop), then 535 arrived without it too...ok, hardware limitation. then...532 has it. but there is no way 532 to literally have a better display than 535. i bet it has the same display just smaller.
what about 730? well, it was launched along with 830. my guess is they needed more factors to differentiate those 2 phones. so yea, here comes marketing factor.
you know, i hate ms for doing that. there is no point to screw your customers this hard. want more differentiating factors from a phone to another? how about work more on hardware and dont screw a perfectly capable software? gladly, turns up that they keep learning from nokia's and their past mistakes lately. after revigorating 5xx family, especially after X30 lines from nokia weren't trully upgrades from x20., now on 6XX family they look like they are revigorating that family even better than 5XX. (see how capable are 640 and 640XL, and how they dont have ANY flops. for a 6XX phone ofc)
(yea, frustration is big for not havin glance on my 535 after it really grew up on me on my old 620)
It is a hardware limitation.
The 520 never had Glance, it has a cheap display too.
The 530 doesnt have it, naturally.
The 532 is odd to me, but I guess its a renewed emphasis on Glance, or perhaps shuffling some priorities around inside the device that we aren't seeing.
The 535 doesnt exactly have the CBD previous Glance-equipped devices has, and I think thats a factor. Considering the touch issues, we know things were cut. We may just not see them.
Maybe the panel of such devices can't be dim enough without flickering, looking bad or otherwise using too much power?
It's not "better display" necessarily, although it could be, its more, "better suited" display.
the 730? My take is that it has a similar AMOLED panel to the 930, which too, doesn't have the memory required to keep things displayed without constant refreshing. Probably a differentiation bonus too.
You can hate whoever all you want, it doesnt change the fact there's a boatload of decisions and tradeoffs made on a device.
Its such a tiny feature on the spec-sheet, and to many non-Lumia users it doesnt matter.
There is no such thing as just making a better device, there's always a tradeoff somewhere. and in the 640's, it isnt immediately obvious which is good, but somewhere costs have been cut or costs absorbed.
