I'm curious to know how many of you or how many of those that complained have some sort of experience with electronics? and I'm not talking about the type of experience you learn from a book that is given to you by somebody that decides what content you will learn. The type of experience I'm talking about is the one where you actually have a curiosity, one that doesn't need a book, ignoring what the "usual learning curve" should be and is guided by the need to know how everything works, and never accepting one reason or one opinion even if the one speaking is the manufacturer.
In my case, as I’m well in my 30s, some people see this as just another know-it-all telling others what to think. Others see this as exactly the type of experience that will never stop enriching your database of knowledge, its an obsession, its a compulsion, it annoys a lot of people, myself included, but it just needs to be part of this episode and might come in handy for a future one. It doesn't always come as a very diplomatic entrance but if a forum tends to be more of a resourceful conversation starter instead of the usual Happy mix of trolls, admins that pretend like they know but always serve GENERIC crap or punish those that create a thread that's been created a hundred times before just because of "forum rules", then the true power of a community is advancing convention and benefits the masses.... I'm not saying I'm part of this group but why is it that most of the civilization changing Visionaries don't finish school or tend to not follow standard practice but instead they take the long way to whatever goal they want to reach...... I believe this is exactly what pushes me forward because it's just me myself and time.
Where am I going with this, are you asking? so first I felt like I had to explain why my answer was harsh, but it's not. When you start this self-taught process early on you start to develop reflexes such as purchasing an accidental warranty with my first drone, the spark and this allowed me to push the spark to its limits and Beyond and if you go look up my username on DJI forums you will see that some of the administration over there has "organized" my threads and put them in a place where they are not super visible because they Disturbed convention; like making sure you understand how The Accidental warranty works and in the name of science you push and push and push Until It Breaks while staying within the guidelines knowing that in a week or two you'll be able to start again for a 0$ or very low cost. In my case I destroyed 4 Sparks and DJI were not able to give me any responsibility or forcing me to pay for the replacement, but I did because I just wanted to get the Drone faster. But the spark yes it does drift like every single other drone for every single other flying object ever created unless there is not a single millivolt powering it
There are three components that are pretty much 95% of the behavior in flight, compass, the gyro and the GPS, also includes the barometer / downward facing visual positioning sensor which one is using air pressure and the other Sonar. In most cases the gyroscope is the one that always causes
major problems because it is the only one that actually has moving parts and when I mean moving parts I mean over time it tends to drift off it's Center axis and needs recalibration. . It's also the only sensor that your drone cannot lived without because take away the GPS take away the compass and the sonar but if you can see it, you can still fly it. On the other hand without the gyroscope when you push the left joystick up the drone has no idea where up is or left or right, according to its own position.
The gyroscope also serves as the Baseline for all the other sensors and because of this very reason, if you have a gyroscope that isn't functioning with the Precision it should, the other sensors, especially the compass and GPS, they have no way to compensate so they usually go into that safe mode what we call attitude which pretty much leaves flying up to you. And until it didn't start to compute the measurements correctly it will be at the mercy of the elements like wind…assuming the gyroscope functions correctly (which can be confirmed in a perfect weather condition if you press forward the Drone flies straight and forward, if you have a deviation such as the Drone flying straight but at a slight yaw angle like I had many times with my spark, or perhaps never being able to have the gimbal centered and always at a slight angle off horizon).
For the inspire, I have disassembled 3 difference models, a V2, a Pro (i think) and my very own V1. Two of them had no previous history of crashes but as many have pointed out it had a head of its own switching to manual flight modes without any warning or pattern.
I discovered a pattern in 2 of them. What I found in common were tiny fragments which had no apparent origin within the GPS module. Both drones had fragments that were metallic as they stuck to other metallic parts and would be easily disturbed by the magnets in my screwdriver. I've been carefully looking at the possible origin of these fragments and unfortunately I have no idea. But is there anybody here with that problem willing to disassemble the top shell where GPS is housed and can remove the Faraday cage that Shields the GPS controller and circuits from any other interference and see if those fragments are apparent and if so clean them with the slight press of compressed air and immediately test the Drone for 2 3 5 or 10 flights and confirm if this is still an issue I certainly will be doing that when the rest of mine maintenance is done.

EDIT: I can confirm this has fixed all GPS related issues for me. Below is a signal report of 2 similar flights, the one on the left is before the GPS maintenance. The signal was constantly going from X to 0 to Z
