For the past few updates, I noticed that on wakeup the clock shows the time the phone went to sleep.

Has anyone else seen this?

I have received my UBports edition phone this week and that up powering on and setting up that it is buggy. Cellular did not work for me and the menus where a bit slow, did not want to go to previous page and did not save settings for cellular apn and carrier. I notice too that the back of the phone gets too warm and quickly over this Quectel EG25-G component too, which is not a good sign. Another thing is that the auto update over wifi almost froze the phone up.

For cellular I use T-mobile here in the USA that uses a micro sim card. The sim card adapter that came with the Pinephone is flimsy and didn't work so I used one I got from T-mobile. Upon updating the UBports It did not fix the cellular issue as well.

If this is the current state of UBports is there an alternative OS that works close enough to be a daily driver? I heard of this Mobian os but what is it exactly and will it do better than what I have now with UBports?

I've been having issues with my Pinephone detecting my music files from my Micro SD Card. I ended up buying a 256GB Micro SD card just so I can take all of my music with me on the phone, but for some reason the Music app says 'no music files detected'.

Does anyone know how to get the headphones to work on UBPorts edition?

I have the switch in the ON position, but the sound still comes out of the speakers.

Hi all,

I did a LTE max bandwidth test, on a good place for being alone on the carrier's antenna (LTE 2600, 20 MHz, 1 out of 3 panels directed right into a big forest.
Reached 140 Mbps few seconds and was moving from 125 Mbps to 135 Mbps at low CPU usage (around 20%)  half of the time : seems to work really fine, as the maximum possible value of LTE cat 4 is 150 Mbps 


However, when using modem, the phone has lots of "seizures moments", during few seconds it lags a lot, freezes a lot, and then come back to normal during few seconds before becoming mad again. It's 50/50 of the time.
When doing the same tests on WiFi, the issue does not exists : it only exists when using modem.

It's not due to temperature as CPU and GPU temperature shows approximately 50°C or even below when the problem already occurs. When the problem occurs, the download bandwidth falls back to almost 0 to few Mbps, and goes up again after the CPU behavior goes back to normal.

Viewing CPU usage on "top" command, within and outside "seizure" moments, the order of which program was using the CPU (aria2, bwm-ng, lxterminal etc) and proportions were the same, but during seizure moments, every usage value is just strongly multiplied.


Is this a known issue? Is there some software workaround about it?
It looks a little bit like CPU power issues, as for Intel/AMD CPU and VRM, in case of insufficient power supply or too hot VRM, CPU is repeatedly doing short freezes waiting things to be normal again, giving similar symptoms.

Also, when enabling modem with low backlight intensity, the backlight intensity is lowering.

But in the others hand, when doing uplink bandwidth test, the problem does not occur (while according to lm-sensors, uplink is consuming more current, 1.2 Amps instead of 1.0 Amps).

I'm using Mobian kernel from here https://gitlab.com/mobian1/devices/pinephone-linux, downloaded and built on 2020/07/19, on Pinephone UBports community edition (1.2 if I'm right - at least I'm using 1.2 DTB).

How to go further in the understanding of this issue?

When trying to open an exFAT formatted drive in Mobian's file manager an error message pops up saying: unknown filesystem type 'exfat'

I tried installing exfat-fuse and exfat-utils, but still get the error message. Are there some additional things missing that are keeping this from working?

Has anybody found the perfect setting for the mouse pointer using the touchpad? It's very sensitive and hard to use.

Hi all,

This is not a really serious issue, not sure if something can be done in future revisions or not, so this is just in case.

When doing some tests with the maximal WiFi bandwidth (iperf, wget, aria2c etc), on a 40 MHz access point, it's about 100 Mbps if bluetooth firmware is not noaded (to find a way to disable bluetooth chip while keeping WiFi enabled, I removed the rtl8723cs_xx*.bin from initrd.img)

However, if the bluetooth chip is working (firmware loaded), even if set to "disabled", the Wifi bandwidth is capped to 50 Mbps (even when changing WiFi access point frequency from 1 to 13)

As bluetooth and WiFi are both operating at the same frequency range, this is not completely surprising, however I already used devices on which the difference isn't as much.

And... I guess that's all I have to tell about this didn't played a lot with the 4G modem, I have a spot in the forests where 1 out of 3 panels of the operator's antenna is directed to nowhere in the forest : this is the best 4G bandwidth testing point ever. I'll probably check it out soon with the pinephone

Keep up the great work!

PS : Using "UBports Community Edition" model, which is supposed to be 1.2

Been using Mobian for a few days on a couple of different phones and with different SIM cards. Yet I have been completely unable to get mobile data to work at all. I have the icons 2G, 3G, 4G etc but there is never an actual data connection, yet from what I have read it should be working?

I am not sure if it is because the SIM cards that I am using are from piggy back networks - GiffGaff and Virgin Mobile in the UK - or whether there is some setting or set up that I am missing. Both SIM cards work in both phones and have data connections using UBPorts, this problem only occurs in Mobian.

I have tried setting up the APNs using the correct settings multiple times, with no luck whatsoever. Is there another step that I am missing?

i'm crossposting on Postmarket OS and ubports subforums since it's pretty relevant on those too
