Sometimes going back without wipe works. There was a similar issue when attempting going from 9 to 8 (if I recall correctly) but OFTEN it will work if changes were minor, but do not expect it in general unless they explicitly say so. And the changes 20 to 21 as well as 21 to 22 clearly was not minor. So stepping back without wipe is unlikely to work.

Did you wipe user data between flashes? In general there are no compatibility going backwards only forwards. So you should not expect a stable system if you do not wipe your user data stepping backwards.... It is just as when you switch between Stock and Lineage (in either direction). You must wipe the user data.

This COULD be a thermal issues. IF a device is quick charging while using GPS at the same time, the risk of overheating is quite high. (But sure the phone OUGHT to throttle down the charging rate if the temperature gets too high) In general if using a phone for car navigation I would strongly advise to charge it before the trip. So the battery is not charging while the device is hot. See e.g. this

Battery stamina MUCH improved with 22. Here 20, 21 and 22 within the last few days;

I do believe that there was an immediate visible change with the boot and redraws from 21 to 22, Will report back on the battery after some hours 🙂

I would not have noticed if you had not said it... So if it helps someone, then fine by me 🙂

Installed Test22...

There should be a charge_full_design and charge_full also, that might help the calibration. Found this googling https://dev.bettermobileapp.com/article/10435402/-+removed+-

I saw no substantial differences going from 19 to 20, but did from 20 to 21.

....sorry for the random order it ended in. Note that GSAM has a bug, so any traffic through VPN is logged as WiFi, even if you turn off WiFi completely.

I have no idea how to pull that info. At best I can give you what GSAM can tell...

Sure, how do I pull those?

Well to give you some valid data I would have to flash a phone with Test20, without the VPN, wait a day or so, and then flash Test21, wait a day or so... So it will clearly be faster to see if someone else without VPN have a battery monitor installed, and see the same difference switching from Test20 to Test21.

Well I have NetGuard active all the time, It will be a show stopper for Lineage for me if that no longer works.

Yup

Despite the more aggressive power management, to my surprise the Test21 is substantially MORE power-hungry than Test20?!? see below from 3C All-in-one toolbox. (It looks similar on the rooted) - note also the x on the WiFi, Mobile data, the screen dump is taken shortly after unlocking with fingerprint. Roughly at ratio 7:4 or a factor 175% And no, there aren't additional stuff running. I checked with Greenify and Android Assistant and only a few user and system apps I explicitly have white-listed are running

Test21 seems to be a little TOO aggressive on the power save, When left idle it decouples the WiFi so check for mail and the like is not performed. When unlocking you can see that the WiFi icon is not there, and only appears after a short while. If you immediately after unlock open something that uses the net (say Android Market) it reports "No internet", but clicking retry and it will work once it has reconnected. This aggressive option can be very nice for special use cases, like when the battery is close to depletion, or when you need an extra long stamina for say a trip. But

I have moved some posts on replacement phones serial numbers over here https://community.fxtec.com/topic/2478-fxtec-repairability-plans-for-the-pro1 Might not be the optimal place - but less off topic.

You should state if it is qwertZ or qwertY variant.

I would suggest to wipe and retry, and then try it without the restore for a short while, to see if it is stable. And then try to restore in small bits to try to pinpoint what somehow interferes with the system and makes it unstable/

Note that your image indicates you placed the magnet a bit away from the sensor, so if if you experience problems, you might want to try to move it a bit. See the image I added here

...Forgot to say that Test21 installed smoothly both with and without root here too. (I did noticed that it in both cases after boot was somewhat slower redrawing the home screen, especially the clock widget. We are talking perhaps ½-1 second or something equally ignorable. Just reporting it as a noticed difference, Later redraws works just fine)

The mic placement is clearly intended for noise-reduction. And I have no idea if the mics are handled as individual mics and the noise-reduction are done software-wise, OR if it is some chipset function using two physical mics, but only giving one mono stream of input to the system. I would not be surprised if the second was the case. Anyone knows? @tdm ?

If my memory do not fail me, they explicitly told they would do exactly that. 🙂 ADD: By afterthought it is actually encouraging to know that they thus initially have allocated more than they have needed. That is the ratio of units that had needed replacement so far has been so much lower than what they expected so they still got some of the initial ones available to send to you eight months later. 👍

Sure, just tell me what you need me to do 🙂
