SIM card not detected when using multi-boot
« on: August 31, 2021, 02:34:54 am »
Hi all,

I recently decided to try Linux on my Cosmo, up until now I have been happily using Android on it without issue.

I downloaded the Linux installer (cosmo-customos-installer-v4 from planetcom) and set the partition for 50% Android and 50% Linux (Linux on boot 3).  All went well on the Linux side but when I booted back to the default Android the SIM card was not detected.

Looking at the front display I can see the mobile data signal strength indicator and when in Linux it detected mobile data, yet Android did not.

I panicked and restored the device to the factory Android install (reserve all space for Android) and the SIM slot was detected again.

Has anyone else seen this?  I am assuming it is something to do with the default Android image installed during multi-boot mode (but I am just guessing).

Many thanks.
