after getting 14 satellites and take off, gps signal suddenly drops to 3-4 satellites. I experienced that 7-8 times. Only one time I got 23-24 satellites and had a flight without any satellite loss. Is it normal in low altitude zones (150m)?
It's not normal to lose GPS if the drone is in open air with nothing blocking its sky view.
should I deliver the device to a warranty service?
Only if it's a hardware issue that is causing the problem.
One possibility is that there is some GPS jamming in the area you flew.
That's very uncommon, but I have seen a report of it from your part of the world.
To check try flying about 20 km away and see if things are normal.
The risk I see, if it loses the RC reception too, drone wont be able to return to home, so I cant keep flying like this, right?
That is correct.
Oh I also control the drone from my balcony, Im not sure if it affect anything.
That won't affect your GPS.
