Crimson image testing thread II - July 2025

I upgraded to crimson to see if it would fix some issues I’ve been having with calls and sms, unfortunately it didn’t. So here’s a list of mostly issues I have:

  • Calls
    • incoming calls usually unavailable, even if the screen is on and unlocked, sometimes but rarely they come in (usually if first placing an outgoing call or receiving/sending sms)
    • outgoing calls work
    • modem randomly deregisters when sitting with screen off requiring me to enter the pin again (sometimes several times a day, sometimes it’s fine for multiple days)
  • Proximity sensor
    • doesn’t work, neither in Calls nor in Mobile Settings (worked in byzantium)
  • SMS
  • MMS
    • haven’t tested in crimson yet, in byzantium the same message multiplication happened as with sms
  • Camera:
    • Auto white balance rapid switching from cold to warm (A to F11) in indoor light conditions
    • auto focus doesn’t focus on close objects <1m away, turning auto off and back on will make it focus up close once, then not any more, it randomly stops autofocusing until disabled and enabled again, on close objects sometimes it completely misfocuses requiring manual focus
    • taking images works
  • UI
    • switching between apps still takes several seconds (for example clicking the button to open Calls or SMS from the Contacts app, or long pressing a button from the pull-down menu to get into mobile network or wifi settings), usually it’s faster to go to the app switcher and manually switch to it
    • I did notice an improvement in UI responsiveness and smoothness after the upgrade which is good.
  • Hardware (off-topic but want to mention it anyway)
    • the handset speaker stopped working, I took it apart and found metal shavings stuck to the membrane inside, sticking it hard to the magnet, had to carefully clean them off with blu-tak and reassemble the entire phone, now it works again (I guess don’t use the grinder in the workshop with the phone in your pocket!)
    • the plastic cover over the modems started cracking around the screws even though they aren’t overtightened, seems like the plastic is becoming brittle

I mostly use it for calling and SMS since the battery life isn’t really good to use as a primary unless you have it on charge all the time or carry spare batteries (charging them is a pain since there’s no external charger).

I’d really like if the call and sms issues were prioritized. What good is a phone with such big call and sms issues?
