Receiving Call During Sleep Experiment/Experience
#1
Information 
My Experience And Update To Receiving Calls During Sleep:

My Pinephone model: UBports Community Edition Hardware

Several weeks back I tested out receiving calls during deep sleep. I had no trouble receiving or making calls whatsoever (while phone was awake). During deepsleep calling from a landline, the earpiece would always ring on the caller end. No ring would show up on the Pinephone (under deep sleep). Basically, receiving calls during deepsleep did not work for me then.

Yesterday I downloaded a new image since @a-wai 's  announced "transition."

Code:
uname -a

Linux mobian 5.9-sunxi64 #3 SMP PREEMPT Tue Nov3 16:24:16 UTC 2020 aarch64 GNU/Linux

I retested calling during by putting power saving mode on sleep after 5min idle.

I waited 30 minutes and made a call to my Mobian Pinephone using a landline.

Here is what I noticed during testing Nov 5, 2020 using an AT&T network:

  1. As the first ring happened over my landline earpiece, Pinephone lit up showing wifi signal connected (no ring from Pinephone yet),
  2. Then cellular bars showed connecting, to connected
  3. After the 6th ring on my landline earpiece, the Pinephone screen went black again and the 1st ringing sound then began between 6 & 7th ring on the landline earpiece (screen still black but ringing sound came through giving me ability to pickup the call Smile).
  4. The Pinephone did ring/wakeup from sleep for the last ring! This was on my first call. I repeated this process/log twice under sleep.

To sum it up: My Pinephone itself does successfully wakeup/ring on the very last 1 or 2 rings for me. Of course you have to pick it up right away (or you can call the number back).

This is good news for me.

I'm not sure if other carriers behave differently (I am not a telecom expert). Maybe comparing/noting reports/phone behavior can lead to finding potential ideas/solutions (if others have an issue).

Maybe others have experience/report details that may in the end help lead to an idea/debug/solution (if this is still a problem for you). I'm not sure if other carriers behave differently (from the number of rings- I am not a telecom expert). Maybe we can compare reports.

Just posted in another thread I have pretty much exactly the same experience this afternoon.
