Hello.

I want to report on all technical forums, an issue that I have encountered in MTK6753. It's about the GPS module of the chipset in some navi apps.
I own a VOYO Q101 Phablet (chipset MTK6753, 2GB RAM, 32GB Flash-Memory), with Android 7.0.
Despite the fact that the chipset model is MTK6753, when reading the prop.file I can see that the GPS module is based on MTK6735.

Scenario:
Firstly, we need to get the "GPS Locker" app from Store, in order to get our "real-time" no. of satellites in the notification bar.
Secondly, we need to install Waze and Google Maps (two navi apps, well known in Europe ans US) - in order to do the test.

1. We are turning on the Location. We can choose any option from "Device only (GPS module only)", "High accuracy". The following problem occurs in both situations. Let's choose Device only.
2. Open GPS Locker and get a lock. Very fast, I get a lock in 3-5 seconds (outside) and 10-15 seconds (inside a building).

No. of satellites: 15/17, 16/17, sometimes 18/20. So, no problem with the antenna or other stuff ... Okaaay.

Now, 3. Open Waze or Google Maps and, in the next second (immediately) slide down the notification bar (in order to see the GPS Locker status).

We can see that the no. of satellites decreases drastically, sometimes till 0/20 satelittes ! So, we have no GPS in navi apps. This is the problem I want to emphasize.

Very good reception in GPS status apps (like GPS Locker, GPS test, etc.), but when opening Waze or Google Maps we have a huge drop in the number of satellites available.
Sometimes, it goes down till 0, and after 10-15 seconds fluctuates between 3-4-5-6 satellites, then suddenly back to 0, etc., etc.

Where is the problem? Have you encountered this problem?

Any "tricks" from MTK 65xx (from Engineering Mode) don't work (because, in fact, it's not a problem with the GPS hardware itself). It's not a problem with antenna as long as I got 17-18-19 satellites with YGPS/Gps Locker/GPS Test or other tools. The problem is that, when I open a navi app (like Waze, Google Maps, etc.), the no. of satellites drops to 0...

PS: Lol. If I try to slide down-and-up the notification area several times (for 10-15 seconds, like a crazy man), I also have a drop to 0/20 satellites. So, this is another "action" that will also kill the GPS ...

Thanks!

Anyone? All other issues have got at least one answer... Is this one so unmanageable?

Thanks!

I have been trying to replicate this but no success with any of the apps you mentioned.
Maybe you should do a screens recording so others can see

Two questions
1. Have you tried this same procedure on other chipsets?
2. Are you saying that Waze and Google Maps aren't working on your device?

Here you will see the problem .... losing GPS sats in online apps (Waze, Google Maps).
I will tell you again the problem:

GPS problems appear when entering a navi app. So, after opening GPS Locker (an app that "lock" the GPS), you can see that everything is ok. +10/+12 sats in use. When entering a navi app, the GPS suddenly drop to 6-4 sometimes 0 sats ....

There is no problem with GPS antenna as long as I can get a lock, with +10 sats, with +30dBm SNR...
1. I have tried to disable Google Play Services (which can cause a lot of troubles .....)
2. I have tried all Location modes (High Accuracy - which is a bullshit, Power saver - never to use, Device only - this is good. The raw GPS data is the best, everytime. I don't need any "improvements" from 3G/4G/Wi-FI which can add errors up to 10-15m........................).

Anyone please?

Is very annoying ... to drop the sats in GPS apps... despite the fact that I have a good reception. Could be a firmware problem?

Google maps/waze and mainly all GPS need Google Play Services to get localisation
