Alcatel 1S 2020 Specs:
GPS Yes, with A-GPS
NO mention of other GNSS systems.
"With RTH my Mini 2 always lands within 30cms of the takeoff location."*
Has NOTHING to do with GPS accuary of the smart device.
“Litchi and Fly always count more then 12 satellites, even 16 or 18 or 22. Which is impossible”
The Mini-2 uses GPS+GLONASS+GALILEO GNSS-Satellites (24+24+24=72 Satellites total)
“my real outdoor-gps has a screen to inform on 12 sattelites exactly (only), no more.”
Garmin Montana 680 with 6 bars (GPS-GNNS) & 23 visible satelites:
“since there are 24 satellites in total”
The GPS space segment consists of a constellation of satellites transmitting radio signals to users. The United States is committed to maintaining the availability of at least 24 operational GPS satellites, 95% of the time.
To ensure this commitment, the U.S. Space Force has been flying 31 operational GPS satellites for well over a decade.
-BeiDou, or BDS, is a global GNSS owned and operated by the People’s Republic of China. BDS was formally commissioned in 2020. The operational system consists of 35 satellites. BDS was previously called Compass.
-Galileo is a global GNSS owned and operated by the European Union. The EU declared the start of Galileo Initial Services in 2016 and plans to complete the system of 24+ satellites in 2021.
-GLONASS (Globalnaya Navigazionnaya Sputnikovaya Sistema, or Global Navigation Satellite System) is a global GNSS owned and operated by the Russian Federation. The fully operational system consists of 24+ satellites.
-IRNSS is a regional GNSS owned and operated by the Government of India. IRNSS is an autonomous system designed to cover the Indian region and 1500 km around the Indian mainland. The system consists of 7 satellites. In 2016, India renamed IRNSS as the Navigation Indian Constellation (NavIC, meaning “sailor” or “navigator”).
-QZSS is a regional GNSS owned by the Government of Japan and operated by QZS System Service Inc. (QSS). QZSS complements GPS to improve coverage in East Asia and Oceania. Japan declared the official start of QZSS services in 2018 with 4 operational satellites, and plans to expand the constellation to 7 satellites by 2023 for autonomous capability.
That’s a total of 94+ other GPS Satellites.

You continiously mix up GPS accuracy of the drone and the smart device.
“The text of the second link is a joke.”
It’s reality and proves the used smart device’s GPS accuracy is not up to the task (GPS-GNSS only).
“So you are advised to Increase the default 10 meters to ie 20 meters Minimum accuray to solve issues”
That’s YOUR conclusion, and nowhere written.
“It seems to me that Litchi messes up the Maximum and Minimum accuracy. Max-Accuracy is ofcourse a smaller absolute number (so with Less Tolerance) then Min-A.”
No, You are messing it up.
Again: Reading comprehension is not for everyone.
“I stopped “Reading comprehension” somewhere around 1980.”
“All (!) customers always complainted Afterwards (!) they had ment “something else”.”
In other words: You never comprehended what they really ment.
