[Q] NFC similar to car dock - Moto X Q&A

Is there a way to set up an NFC to act similar to the original droid 1 dock with the magnets? So that when its at the NFC certain things happen, but then when it's taken away from the NFC it reverts back to how it was before being at the NFC.

There's no simple way. NFC Tags are by nature passive - when your phone's battery's magnetic field comes into contact with the tag, the tag is triggered by a quick burst of power. It happens only once - if you remove the magnetic field, then place it back again, it triggers again. There have been a few custom ROMs that allowed what you're looking for by constantly/actively checking for the NFC tag.
Otherwise, I don't know of anyway to do it. In theory, an app should be able to check periodically (like every minute or two) to see if the nfc tag is still in contact with the phone and once it's not, trigger reverting back. But I don't know of any app that has built that in yet. Plus it might have battery drain implications.

[Q] Demagnetize phone?

Recently I was getting a kinda weird effect. My compass now always directs to the bottom of the phone/screen, except when it is in open state. I think I have magnetized some parts somehow, and it is kinda disturbing when I want to use Layar or anything else what uses the built-in magnetometer.
Is there any way to fix this?
Theoretically putting the device into a simple depolarized magnetic field would solve the problem, but I don't know if it will damage the phone itself or not.

There are no magnetic components in the phone.
That means that it can't be magnetized.
I'm sorry to say that your magnetic field sensor itself is shot.
Note that putting the thing into a demagnetizer, if the sensor wasn't already dead, would DEFINITELY destroy it.
How do I demagnetize my cell phone screen
Actually phones have a magnet for the compass function and apps such as google maps to show which direction you are facing. Also, if you put your phone near magnets a lot it might magnetize metal parts in the phone messing up the compass. Demagnetized get your phone would demagnetize both the unintentional magnets and the magnetic compass. Please don't do that.

[Q] Issue with Navigation apps and power fluctuations

Hi, I'm pretty sure this is a unique or rare situation I've experienced, so I'm starting a new thread, but will endeavour to find similar issue threads.
On my motorcycle I have mounted a Brodit powered cradle for my Xperia Z. I figured it would be the ideal way of providing power to the phone while I travelled, and would allow me to use the phone as a Sat-Nav, utilising one of the many sat-nav apps (Google's offering, mapquest, copilot etc etc). Using the Brodit allows full use of the waterproof attribute of the phone - no socket ports need to be opened, and the phone doesn't need to be in a transparent case in inclement weather to prevent damage. I chose the Xperia Z (over other phones eg HTC) with this usage in mind.
It's worth nothing that I had a previous similar setup for my HTC Desire HD: without the powered mount, but using the charging socket and a transparent case over the phone for rainy days. It worked perfectly.
However - I currently am experiencing the following issues with the Xperia Z setup:
Firstly - The Brodit mount is 'not' weatherproof. (this is not Brodit's fault - it's not marketed as weatherproof) It provides power to the phone perfectly, until the first bit of rain, and then it starts to fail - either cutting out completely, or not providing enough current to keep the phone charged while the GPS / Mobile Data / Sat-Nav-App systems are turned on. (Previously it would provide enough power to increase the battery charge even while all the navigation systems were active). This is something I shall look into but I'm not really aggrieved about it - the cradle is NOT sold as an outdoor item so I'm not going to blame Brodit for this. I suspect that the issue is water getting into the 'spring-stud' connections and reducing the current flow. I'm going to see if I can adapt these connectors. If anyone has any further ideas or suggestions for better powered cradles too - I'd greatly appreciate it!
Secondly - and this is the main issue - when the power supply fluctuates (see above) the Sat-Nav Apps behave in a highly irritating manner : They instantly kill the viewport (it goes black), and also forget the current GPS location coordinates, and forget the viewport display setting: ie - show my current location in top down or perspective viewpoint and viewpoint relative to 'North'. When the power returns, the viewport, depending on how the app is being used, either returns to the start of the journey, or to a point in the journey where it remembers, but always loses the current location viewpoint settings.
This is obviously highly distracting, firstly you instantly lose your whereabouts which is dis-orienting, and secondly you then have to stop and reset all the settings so that the sat-nav display is back to doing what you want it to do. On a motorcycle this is further aggravated with the need to remove a glove in order to control the phone. On a recent trip to France I had this happen no less than 5 times in as many minutes right at the start of the journey.
It should be noted that I wasn't using the GoogleNav system in full directions mode. I find this mode misbehaves terribly if you're trying to use a customised route (see below for more info), and so I tend to load up my customised route so that it displays over the maptiles, and then I either just center my viewpoint on my location, or utilise the 'Preview' mode and again, center the viewpoint on my location (this mode displays a useful 'current direction of travel' arrow on your location).
Has anyone experienced issues like this, and if so - did you solve them? Or does anyone have any ideas for how to get into the configuration settings so that I can turn off the screen blanking and signal losses when the power fluctuates?
Thanks
Notes on Customised routes in Google Nav:
As I noted in this Google Product forums thread (just in case anyone else is involved) : https://productforums.google.com/d/msg/maps/DwPoT0pklas/sG0-sFYozT4J :
When in full 'Directions' mode, Google Maps a) doesn't poll your location accurately or often enough when slip-roads (off-ramps) are involved, and re-calculates the route to the next/final destination every time this happens - thus abandoning your carefully planned route.
So - I take it no-one has seen a similar issue or knows of a way to stop Google Maps losing all it's signals when the power is cut off?

Tasker, Pixel 4, and setting ring profiles when docked, based on which dock I'm using

Hey guys,
Looking to up my game with automations on my phone and set ringer profiles. I have WiFi on all of the time anyway, so I'm setting ring profiles based on being at work, being at home, night, day, etc.
But I'm thinking of kind of next-leveling it, and wanted to see just where I would start, if I need add-ons for Tasker, stuff like that.
So I have only gotten around to making a 'night' routine for Tasker. IF I'm home and IF the time is in a certain range, it goes silent. That way, if I'm lucky enough to actually be out, the phone still makes sound, but not when I'm trying to sleep. The next level I would like to try is different profiles based on what I'm doing at home or at work, using NFC. More specifically, I have a wireless charging dock at my desk, and one at home. I work IT, so I spend about half of my day at the desk, and half working the office floor. The floor is a little louder than my office (OK, a LOT louder), so I would prefer a different ring volume for each.
So when docked (At the dock at work), I'd like my volume to be minimal. As soon as I take it off the dock (But still at work), I'd like it to be mid-range. Re-dock it, goes to the low volume again. Leave work, full volume.
Similar thing I'd like to try at home. Any time of night, if it's not docked (In the home dock), it's a relatively normal volume. Dock it, and the hours fit into the specified range, and it goes silent.
I'd also like to change the behavior of the screen based on these. At work, the clock is on, at home(When I'm trying to sleep), the clock is off and the screen is dark.
So I know to do this, I need NFC tags on each charger, I've looked up interference from the chargers, and it seems to be a mixed bag. I could play with where to place the tag exactly, that's not an issue, but if I'm going to automate, I'd love to do this as automated as possible, if you know what I mean. Rather than tap it on a tag, I'd love to just set it in the dock or pick it up to activate it. So that's it. Anyone have any suggestion on a brand of tag, a specific criteria I may need to look for (I don't know if these things have ratings or anything like that), and any extensions or companions I need for Tasker to do something like this? Any help, as always, will be greatly appreciated, and feel free to ask followup questions if I was unclear on anything.
I don't really see why you NFC. Assuming you know whether you're at work or home based on the WiFi, then you can know whether you are on a wireless charger based on a profile state of power -> power -> wireless.
As a completely unrelated idea, if your P4 is rooted, and the device spends a bit of time on a charger, you might look at Advanced Charging Controller (ACC) (XDA thread

Part of it is on the dock in the office vs. off the dock, walking around the office. Part of it is on the dock at home, vs. plugged into power, sitting next to the TV in the living room. Same with work. If I'm working in a conference room, I might just bring a charger and cable in there, but might still want the ringer loud. SO I'm kind of compartmentalizing both work and home, based on which area I'm in.
Part of it is also playing with Tasker, NFC tags, and all of those possibilities.
And unfortunately, a Verizon phone, so they've hosed me(As usual), and I don't think, even with it being a Pixel, that I can root it. :-
Since I think your question is, do I need any plugins to read NFC, the answer is no.

Oh wait, I see the part now about wired vs. unwired power. Got it!
I'll try that, see how it works for me.
Thanks, your basic tips have helped me. I now have a work day profile, a weeknight profile, and a weekend profile(Morning noisy time is later on the weekend), all based on whether it is charging wirelessly or not and where I am.

Question 90 degree GPS Issue

Hey all,
I moved recently and now rely a lot on google maps (and other location apps) to go to places.
Whine the location of the device fave been spot on, I have an issue with positioning and vector... What I mean is the device reports direction with a 90-degree error. If I am on the crosswalk facing one of its directions, the phone shows me that I'm perpendicular to the crosswalk and when I move up or down the crosswalk, it shows me moving sideways... not sure how to explain it better...
If I'm in a car and moving, the dot moves correctly on the map but I'm being shown as moving sideways on that map...
After doing a Google search on the issue, it seems that other people are also having this problem.
I've tried recalibrating, using the live view to calibrate (which works for a moment and then breaks again) Also tried clearing the cache of google maps, (but other GPS apps are also affected)...
Does anyone know how to deal with this problem?
Try turning off improved accuracy or vice versa...
Clear system cache.

All of this has been tried. even board replacements does not fix it...
it seems to be some kind of a software issue...
Screen rotation is set to manual or automatic? Try switching your settings.
Google Play System Update is up to date? Should at least be from 1st March 2022.
we have a crab in disguise among us... 'transformers~~ shell fish in deguise~~'
jokes aside, the GPS is known to be very unstable. I have the issue come and go... and from what I've heard it's due to signal disturbances.
You'll want to report the issue to Google if you are using Google Maps
Use common sense (or develop it) to navigate.
Constantly being led by a smartphone on the streets is a lousy and dangerous way to live.
Develop a mental picture with critical way points of where you are going and then concentrate on navigating the real world by memory. With practice it becomes 2nd nature.
If it's a complex navigation effort break it down into manageable blocks with start/end way points.
For the car a dedicated GPS is more practical and reliable, but you still need to use common sense for when it glitches... and it will.
GPS is just an aid to navigation... like a map.
Do you have a permanent magnet somewhere inside your phone case, or other source of magnetism that would confuse the on-board magnetic compass?

KingFatty came up with my initial thought. Might be some magnetic interference.
I do know the exact issue you are talking about though. I knew I was facing south (I have an actual compass) but my phone said I was facing east. But I solved it with a simple recalibration. I have to recalibrate at least weekly.
You say you have had board replacements to rule out a hardware issue but if it was a software issue then surely everyone would have it? I can confirm that right now, the orientation is correct on my phone. It could be a firmware issue for your specific device but this requires the manufacturer to fix it.
That leads me to think its some kind of outside interference like a magnet in a case.

Samsung's don't like magnets, truth
It may be the earth's magnetic field in your location. It isn't uniform.
It's actually began a cyclical pole shift which will take hundreds of year to complete. Magnetic anomalies with become more common as the reversal draws closer. I doubt the latter could be the cause but the former could.
I think magnets may indeed be the issue. My bag's phone pocket has a magnet on its latch so it might be the thing confusing the phone. The problem is that from more than 20 different phones I had over the years, the S21 Ultra is the first one to exhibit such side effects from magnets...
I use a car mount with wireless charger, and the mount itself creates a magnetic field that confuses the phone's compass so the phone re-calibrates the compass based on the navigation driving etc. When out of the charger, the phone is still interpreting the compass as though it's in the mount with the magnetic influence, so you just need to recalibrate the compass and it will fix the issue until next time it automatically recalibrates while under the influence of a magnetic field.
That's just how compasses work, they sense existing magnetic fields, and the closer a magnet is to the phone, the stronger the field. If only there was a way to tell the phone you are putting it next to a magnetic field so it knew not to recalibrate itself at that time.

Question Sensors glitch

I have a strange problem with GW5 sensors: My watch is secured with a PIN and Samsung pay is active. After I register body composition, hearth rate sensor blocks and the security lock doesn't work anymore even if I undress the watch and I put it back on. It stays unlocked. The only way to reset the situation is take a SPO2 measurememt or restart the watch.
Besides, occasionally, the watch locks without any good reason and if I enter the PIN it unlocks only if the screen stays on. When it turns off it locks again.
Somebody else notes this behavior?
I have the 2nd problem you have where the phone locks without any good reason.
Thanks for the answer RigoF. I suspect that the two malfunction are somehow related. Would you mind to make this test:
With the watch working normally take a body composition measurement. Once you get the results, go directly back to the home screen. Undress the watch and check if it locks. If it doesn't work, put it on again and go to the SPO2 widget. Take a measurement of the SPO2 and once you get the results the.watch should start working normally again.
I also noticed that doing this procedure improves the accuracy of the sensors. The other way to solve the issue is restart the watch, but in this case the sensors are not always precise.
Yes I was able to duplicate the behavior you described in post #3. It won't lock after the body composition measurement and returns to normal after the SPO2 measurement.
Thanks a lot. I already spotted this issue in two 5 pro LTE that I had the possibility to use, both brand new and with different CSCs. The BIG message to people that use Sansung pay is: If your watch locks with no good reasons when at your wrist, there is the possibility that everytime you take a body composition measurement your security PIN could malfunction leaving your card accessible even if you undress the watch.
UPDATE. I sent the watch to the Samsung service support. They found that the problem was due to the sensor working intermittently. They changed both the main board and the entire back cover. Now the watch works like a charm.
