GPS Altitude fluctuating by 100s of meters - Google Pixel 3a Questions & Answers

Hi,
I use different apps for sports tracking, mostly for paragliding and each of them records highly fluctuating altitudes. Here is an example:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Practically, this was a very constant descent, so it should be more or less a straight line. My girlfriend uses the same apps but on a Pixel 4a and gets smooth altitudes. Factory resetting the phone also didn't help... So I really think, this a general problem with my particular phone or Pixel 3as in general. Does anybody else have such problems? Or even a solution?

The graph you posted only shows the end result and the reason for the fluctuations could be many things.
I would think the app or graphing software you are using would ignore readings that are over a certain threshold, so check the settings. Or you can just upgrade to a 4a.

Thank you! As it affects all apps I really think that it must be a faulty output of the GPS. As those tracks are always recorded in an unobstructed environment (the air ;-) ) I can exclude almost all errors discussed in your linked article. They would maybe explain 10s of meters of fluctuation but not ~500m. Those are also not singular readings but a couple of readings in a row, so not really outliers. I just wanted to check if there are others with the same problem or if my phone is defect.

Trying to understand a supposed battery problem. Maybe wireless.

Alright so the past couple days I have been trying to determine and figure out more about why I am having SOD problems. Yes I understand there is a thread for the SOD but something still bugs me on account a friend of mine has no SOD problems with the same wifi model.
While I haven't had an SOD for a couple days something else hasn't been sitting well in my stomach and that's the battery usage... All of a sudden Android OS is using a significant amount of battery. Much higher than the screen and I don't remember that happening before...
So I downloaded better battery stats and let the tablet sit for about 30 to 40 minutes and her are the results. I am hoping someone will see something out of the ordinary and point me in a good direction.
One I thing I see is that the wifi is on a lot and ar6k_wow seems to to be on a decent amount too. Next test will be removing the Facebook app despite me having it set to no notifications or syncing and see how things pan out since I know the Facebook app is notorious for battery drainage.

Inaccurate GPS

I've been getting some inaccurate GPS readings recently and I've tried the aGPS app clearing and redownloading GPS data as well as flashing the GPS fix (ver 3.1) found here on xda forums. The result remains unchanged. What other steps should I do?
As you can see, the read distance is pretty far lol

If your inside your home your phone can't use GPS, but uses the cellular antennas. So you get an approximate location. Try using your GPS outside. If this isn't your case than try changing GPS region. You can read THIS post
I've tried inside and out of my home and it can get pretty wacky at times. Sometimes its accurate, sometimes it's like shown in the picture above.
But I do get accurate results while I am outside more often though.
Thanks!

[Q] Smart Phones 10 or 20 years from now

here is my toughts i know its not have the details but some points its pretty reasonable
how about your idea?
but i want to be scientific and reasonable
Some things:
I personally feel holding the phone and talking to be quite inconvenient and old-fashioned, so I would predict 10 years from now, the speaker & microphone would/should be replaced by something (maybe directional speakers / microphones / something more hi-fi) so that we can just talk handsfree always without worrying about interference / privacy / all the problems we currently have.
I'm not quite for predicting that touch-screen would be the dominant interface, but couldn't really think of other advanced UI methods that might crop up in the near future. I would more like moving away from the passive device with a display & touchscreen that you've to go to for accessing information towards something like google glass - something that's always there unobtrusively but provides you stuff you want always without all the lookup cycle.
Also, removing the display for something wearable and still not inconvenient (goggle/glass are not liked by everyone) would be a very good technological advance.

[APP][2.3+] Fake gps location

Hey everybody,
Sorry about my English..
Recently I started learning how to develop apps for android, So the first challenge I set for myself is to build an app that could fake my gps location.
I know that this is not an original idea and that there is a lot of apps that do the same thing in the play, but I did it to train myself.
So, this is the result, I'd love to hear your comments and insights.

Thank you very much
Hi there
I have questions on the setting:
1. What would be the appropriate setting to the "move around fake location"
part sothat it will look as close as it is legit gps done its action.
2. What about the update interval, alltitude, accuracy, etc. What should I
fill this number with sothat I can achieve a real close to legit situation?
3. Does this apps only working as like human on foot/walking condition with
the gps turned on? As I see the result is always crossing the building etc.
Without knowing there are things there in the gps path.
4. Is there any timer feature? As like when the moving around fake location
will be actively turn on and turn off meaning at night most likely people
is sleeping, so it shouldnt be keep on moving around...
Thanks and let me know
a good application , but in my opinion not very good layout of control buttons

Battery Details graph incorrect

Hi all,
I think it's since I updated my Z5C to MM, that my Battery Graph is incorrect, the graph starts not at x = 0.

"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

}
I already reset the phone, but still the graph is wrong. Does anyone else have this problem or knows a solution for that bug?
It's not that bad, but it's annoying since I didn't even root or flashed something on the phone.
Thanks for your help
Y-axis does start at 0, it's just not written. X-axis is the time of day...
[Removed]
Yes... well, I know. That's the hour on the x-axis but i meant that the "battery-line" doesn't start at the left of the graph. Normally at the beginning of the graph (on the left) there should be the hour of the day, when the battery was on 100 % before it dropped on 99%. But as you see, that's not the fact.
I think that's how it should look like: (This picture is not of my phone)
Happens from time to time,
even after flashing a completely unmodified ROM (via XperiFirm and Flashtool).
It's only a cosmetic issue, so ... move along
Yup, they just messed it up in a recent update. Fairly useless now, especially for heavy usage as only the right-most 0.5cm ever has any content
