When using messengers such as Signal or Conversations, many devices are unusable for video calls due to an echo caused at the other end. (E.g. FP4, Moto G7 Power, Moto E).
I would like to compile a list of devices which are ok in that respect. I only know of one, the Moto G4 Play (harpia). This is a very old/rare phone now, are there any other ones??
