[Q] Quickcharge on M9+

So I've done a lot of Google searches on this but can't find an answer. Does anyone know if the MediaTek in the M9+ will support Quick Charge or any similar technology?

as the name implies Qualcomm Quick Charge 2.0 is a Qualcomm only feature so no it's not going to work on a mediaTek processor.
what does the box hype on the phone / website say about quick charging ?

Should work with 1.8 ampere

MTK's fast charging is named Pump Express Plus, another certificate not QC2.0.

But there is still unknown if M9+ will work with this technology.

GPS Chip

Does anyone know what GPS chip used in s4 mini ?
thanks

I only found out that it has GLONASS-Support

We can't reach the Galileo satellite in Europe.

Hello everybody,
I wonder why we can't reach the Galileo satellite here in Europe, while the our snapdragon 820 processor support this satellite.
The same says also Qualcomm in they site here:
https://www.qualcomm.com/news/relea...pport-galileo-across-snapdragon-processor-and
I'm using navigon and also a test software from play store, and compare with galaxy s8 it has support Galileo, our Zuk z2 plus hasn't.
Maybe somebody knows why?
Thnx!

The CPU may support the function but its a OEM choice to "enable" the function on the phone. Since the phone isnt made by just the CPU, in order to accommodate others functions for another ICs, or to "cripple" functions based on region only, or even if they dont want to pay royalties for the use of the tecnology, they may not implement all the functions the Chipset supports. This is true for the Quick Charge 3.0, for instance. Commonly used on all SD820 phones, isnt avaiable on Zuk Z2 saddly...

Thnx for your answer, at least I know why!
And it is sad.For the rest and for €164 is wonderful phone ?

I was wondering the same. According to gsmarena, no phone exists with a snapdragon 820 (MSM8996) and supports Galileo. Therefore I doubt that Qualcomm offers this driver/software to manufacturers for our soc.

Since Qualcomm is american, and Galileo is in direct competition with the GPS, they may have disabled it to cripple the ability of the EU to spread the compatibility for its positioning system.

Nope only the Zuk Edge supports it.

It seems that the Chinese Beidou satellites can be used without problem on my Z2. However I can't see Galileo ones either. There're only three types of satellites, probably, on the GPS test app: GPS, GLONASS, BEIDOU.

now that P3 can be rooted, which GPS chip does it have?

Hope it's the BCM47755

Was anyone able to figure this out?

Someone posted in the ifixit comments of the Pixel3XL teardown that the GPS is integrated into the Qualcomm 845 board; so no the BCM47755 discrete chip is not implemented with the current pixel

Navic vs normal GPS

Hi,
I wanted to ask does any body know about NAVIC support in these mobiles , is it hardware or software based. If it is software based can it be installed via zip or apk in mediatek and snapdagon indifferently or u have to ask for special permissions from govt to install them? And how is it different from the normal GPS we have been using all this time in other mobiles. pls do share any difference u found ever in both... like accuracy zoom lvl difference from Google maps etc...

Navic uses a different frequency band and Integrating NavIC also requires hardware changes on the chipset.
These are few hardware chips which support NAVIC
System from Qualcomm has launched several NavIC compatible chipsets – Snapdragon 865, Snapdragon 765, Snapdragon 720G, Snapdragon 662, and Snapdragon 460.
Huawei Kirin 990 SoC.
Mediatek dimensity series

It's completely hardware based and cannot be flashed by a zip or magisk cause it needs the hardware components to be on the SoC.
GPS satellites are American, NavIC is Indian so if you live in India or neighbouring countries you can get a faster lock on the Positioning Satellites. As for accuracy it's upto 1 meter and if you happen to work in Defence then 10cm.
Zoom level in Google maps doesn't have anything to do with the positioning tech or satellites you use.
