Astro Slide - General Discussion / TPU case
« on: April 03, 2023, 12:16:50 am »
Since the "official" protective packs for the Astro seem not to be expected soon and, well, are fairly overpriced, I have been thinking about a TPU case similar to the Astro Protective case. Has anyone already tried to print one?

Astro Slide - General Discussion / Bike mount
« on: February 02, 2023, 07:28:44 pm »
Has anyone found a bike mount matching the dimensions of the Astro Slide? I personally like the variants where the phone is being inserted into waterproof bag and this bag the is being attached to the handlebar. Like this one:

But I have not found bags of this kind matćhing the dimensions of the Astro. Any recommendations?


after the update airmail stopped working for me. Since I have updated yesterday and I have noticed the problem today, I cannot tell for sure if this is connected to the update. Airmail crashes when displaying a mail from IMAP. I have not tried yet to clear airmail date / reinstall airmail.

Does this happen for other airmail users?

Cosmo Communicator - Android / Airmail 1st/2nd class folder selection
« on: March 11, 2021, 08:59:33 am »
For enabling disabling notifications for imap folders I need to distinguish between 1st and 2nd class folders in airmail. I can enable/disable notifications for folder classes, but I have not found an option to set which folder is 1st class (in german: Hauptordner ) and which folder is 2nd class (in gerrman: Nebenordner) in Airmail.

Anybody knows?

Cosmo Communicator - Android / [Solved] Airmail Imap folder abonnement
« on: March 05, 2021, 04:19:00 pm »
I have just added some Imap folders with thunderbird. Does anybody know how to refresh the folder list with airmail? With K9 mail I remember a menu item refresh folders, but I cannot find this with airmail.

Cosmo Communicator - Android / Skype incoming calls/messages
« on: July 08, 2020, 03:12:53 pm »
My Cosmo does not ring or show incoming messages when Skype is not the active app running in the foreground. As soon as I return do desktop or have another app in foreground I do not catch incoming Skype calls.

I already have checked all notification settings I can find and also disabled battery optimization and gave overlay permission.

Does Skype work properly for anyone else on the Cosmo?
Anything else I can try?

Thx. Mith

Two days after upgrading from V19 to V22 my Cosmo suddenly started to behave strange. Most functionality of the taskbar has been missing. The home screen suddenly only had one page. Taks switching became impossible.

The reason has been, that due to a bug in/after OTA update the device has been struck in initial setup mode, where most functions are locked.

This can be solved by running the following commands in a root shell or with adb:
settings put global device_provisioned 1
settings put secure user_setup_complete 1

Initially I thought I had to perform a factory reset, but  then I found the issue on:


Gemini PDA - Linux / apt update frozen on gemian kernel repo
« on: May 08, 2020, 07:36:41 am »
For me apt update froze while processing the gemini-linux-kernel-3.18-stretch repository:

root@gemini:/etc/apt/sources.list.d# apt update
Hit:1 stretch/updates InRelease
Hit:4 stretch-backports InRelease                                    
Ign:5 stretch InRelease                                  
Hit:6 stretch Release
0% [Working]^C            

For me this got solved by installing http-transport-https:

  apt install apt-transport-https

Maybe there is some new https redirect on the server.


Cosmo Communicator - Android / Phone call auto rotation
« on: February 05, 2020, 12:22:54 pm »
With my Cosmo it seems the dual orientation microphone is not working. No matter how I am holding the Cosmo, it seems the speaker is always near to the flash and the microhone near to the fingerrprint reader.

Does anyone experience the same behaviour?

Am I missing some setting? Hardware defect? Not yet implemented?

Cosmo Communicator - Android / Possible cause for battery drain
« on: December 18, 2019, 03:46:18 pm »
I have identified a process "android.hardware.nfc@1.1-service" occasionallly using up one cpu core (top in termux) and draining the battery then. Turning off nfc heals the problem. After reenabling nfc cpu usage stays down. I can see this happen every one or two days.

For the time being it might be best to keep nfc disabled until one needs it. Bug ticket @PC already opened.

Cosmo Communicator - CoDi / CODI update
« on: December 10, 2019, 05:40:11 pm »
Just got a CODI update from V1.1.1.11 to V1.1.1.12. To get the update start the Cover Display Assistant app and press "check for updates". It took two attempts to flash the update. So if it fails, just retry. The flashing takes quite long (the app tells it might be about 20 minutes), so it might be better not to start with a nearly empty battery. For me the battery charge went down from 87% to 82% while flashing. For me the CODI feels snappier and I hope for better standby time. But maybe my perception is wrong.

Using the camera preview on the CODI still is slow, maybe a two seconds lag.

Gemini PDA - Sailfish OS / Sailfish updates without full reflash
« on: April 15, 2019, 04:01:52 pm »
I am mentally preparing for the Cosmo. I don't want to use Android on a phone for privacy reasons (using Debian on the Gemini, but that is not really an option for using the device as a phone), so Sailfish might be the best option. With this a few questions regarding Sailfish have arisen:
There might only be a community edition available initially. Is it possible upgrade to official without having to reflash?
Is it possible to update Sailfish without having to reflash?
What about X11 compatibility, is this possible somehow?
Hardware support (USB devices) and filesystem support is some kind restricted with the Android kernel. Has anyone tried the modular kernel with Sailfish?


Gemini PDA - Linux / maxcpus=5
« on: March 21, 2019, 07:06:11 pm »
Today, just out of interest I had a look at the kernel cmdline and noticed we are are restricted to 5 cpus:

root@gemini:/home/gemini# cat /proc/cmdline          
console=tty0 console=ttyMT0,921600n1 root=/dev/ram vmalloc=496M slub_max_order=0 slub_debug=OFZPU androidboot.hardware=mt6797 maxcpus=5 androidboot.verifiedbootstate=green bootopt=64S3,32N2,64N2 log_buf_len=4M printk.disable_uart=1 bootprof.pl_t=1127 bootprof.lk_t=2950 boot_reason=4 androidboot.serialno=TGRWNRQ8ORQKC6TK androidboot.bootreason=wdt_by_pass_pwk gpt=1 usb2jtag_mode=0

To prove this I tried while running sysbench ( sysbench  --test=threads --num-threads=99 run ) to see the count of enabled cpus:
root@gemini:/home/gemini# cat /proc/cpuinfo |grep proc|wc -l

The count of active cpus never went above 5 (as expected). Does anybody know the reason for this restriction? Has anybody already tried to increase this number, maybe to 10? Do we all have this restriction(might be a problem with my setup, but don't think so)? Where could this be changed (it is not part of the mkbootimg call)?

Gemini PDA - Linux / Bluetooth Headset with Debian
« on: February 13, 2019, 08:46:17 pm »
I have just tried to connect a Bluetooth headset and failed. Has anybody successfully tried?

Pairing has been successful and when turned on bluetoothctl says the headset is connected, but by no way I could get pulseaudio to playback on  the device.

Gemini PDA - Hardware / Pinout of the camera connector
« on: January 30, 2019, 04:01:08 pm »
Does anybody know the pinout and type of the camera connector? Just thinking about connecting a NFC reader/writer to it instead of the outer camera... Anyways, the metal cover might prevent this. Still, this might be interesting for other upgrades.
