| Heat build-up: EG25 or SOC? |
|

After the first hour or so of playing w/ different OS images, the exposed RF-shield (under the battery cover) gets quite hot. I'm was pretty sure this shield only covered the EG25, so flipped the modem kill-switch to off. It's still getting quite hot... so I've got two questions (one of which I can probably answer from the schematics):
1) Does the RF-shield act as a heat-sink for both the modem *and* the SOC?
2) What does the modem kill-switch actually do to the modem? Place in reset? Physically remove power?
EDIT: Took a me a bit to realize that the symbol for the killswitches is split through-out. SW1-A is the 2-pins for the modem kill-switch, and looks like it is intended to cut power at the Q1500 power mosfet. Has anyone confirmed that the EG25 does not draw unwanted power when disabled?

I downloaded ubports from here: https://ci.ubports.com/job/rootfs/job/rootfs-pinephone/ (Chose .img.gz under "Latest Successful")
Extracted to default .img file
put on sd card using:
Code: sudo dd if=/home/user/file.img of=/dev/sdX bs=1M
Put it in the top (sd card) slot in the phone next to the battery. There is no SIM card in the phone yet.
And when I turn it on nothing happens but the screen with the factory test. (Everything passes factory test except EG25, because no sim).
Possibly the battery is really low? (I did remove battery protection tab.) How do you tell? I don't see any indicator lights showing charging or battery level and I can't find the info here or on the web.
Hope you can help!

My pinephone arrived today but as far as I can tell the touchscreen is not working. It boots to the factory test screen but none of the buttons respond to my taps. I don't have a large enough microSD card here at work to try another OS, but I'm assuming if it doesn't work with the test image, I won't have much luck with anything else either.

The screw closest to the camera also just fell out when I had the back off. I tried to screw it back in but either it isn't catching or the threads are stripped. I'm assuming something didn't go together quite right. I'm comfortable taking it apart and poking around but I don't want to void my warranty if it is truly defective.

| Eduroam Wifi Issues |

Hey everybody,
I have the pinebook pro with the standard os that ships with it.
I have a strange problem. when I am at home, I can stay connected to wifi without really noticing any issues.
At work, I connect to Eduroam (https://en.wikipedia.org/wiki/Eduroam) and it works just fine for a few minutes. But then it starts to drop the connection -- sometimes it shows up as connected but is actually not. I can then reconnect but keep having trouble until I reboot the machine.
I went through the suggestions on the pinebook pro wiki (https://wiki.pine64.org/index.php/Pinebo...iFi_issues) but nothing worked so far.
Has anyone else experience this problem?
Does anyone connect to Eduroam without any problem ?
Edit:
Have been at a different institute today and had no issues with Eduroam at all. So it seems to be a local issue.
Update:
Switched to Manjaro: Wifi issues with eduroam are still there. However, it seems to work fine when using a wifi-dongle.

| Is the PinePhone board open source? |

Hi!
I'm researching and developing hardware for Virgo.
https://virgo.org/about/
Our end-goal hardware-wise is an open source mobile phone, and I wanted to follow up with you guys about the PinePhone.
I'm curious if any of the hardware on the PinePhone is open source?
For example, the PCB design, case, display, or anything else for that matter.
Thanks!
-Jacob
PS: I really love the idea of phone as dev platform for mobile Linux, and I plan to pick up a PinePhone as soon as the next batch is available.

If this happens to you, something to try, costs little
This fairly serious, I just spent 2-3 hours to narrow it down
So, I thought I had broke it, the power button did nothing, removed q4os SD, still nothing
For some reason, I tried holding power 15 sec, nothing, thought try longer (and 20+ is right)
Then a short push and started right up, hmm, hmm
Put q4os back in, reboot, same senario (dead power button, hold 20+s, then works (q4os out))
Tried with nothing in SD slot, worked OK, tried with debian bullseye, worked OK,
tried with manjaro, worked OK (reboot worked, after shutdown restarts normally)
Checked 1st 16M, diff and cmp they vary quite a bit,
downloaded a stock mrfixit and updated, 1st 16 match (aside from mbr) (with emmc)
So q4os has some problem with uboot? or ibdloader?
I never did get q4os booted
why the 20 second push????
--edit-- SOLVED
turned out to be wrong card, identical (appearance) card hiding nearby
I wish there was a way to mark cards, that doesn't rub off or gum up SD slot
