I have a ticket opened with Kyocera Support and has been since 8/4/2020. Of course like in other posts, Kyocera was aware of the issue for the past two weeks and told me that a software update was in progress and should be released soon. The software update was available around 8/6/2020. The Kyocera E4810 phone. I downloaded the newly available software version 1.022VZ and it did not fix the issue of Speaker phone mode selection spuriously. I have found that if I plug in my wired headset while phone is powered up, when I decide to remove it from the headset jack on the phone, the Speaker phone mode issue returns meaning when answering incoming calls. To get the phone back to earpiece operation, I have to power cycle the phone. I have mimiced the circumstances causing the issue more than 20 times. The call's audio will emit audio through the earpiece. I then plugged my wired headset into the 2.5mm Headset jack and immediately unplugged it. Without the headset being plugged in, I called the E4810 device from my home phone, I flipped open the cover to the E4810 to answer the call but before actually answering the call using the steps mentioned above, I noticed that the Speaker phone Icon was active on the screen of the E4810 device. When I pressed Accept or Send button, the call answered in Speakerphone. There lies the issue and errors. Explained to Kyocera Support and Vz Support. Still waiting on the next sw update from Kyocera who acknowledged this exact issue. The version os sw I have is 1.102VZ version. Eric with Vz Support is quite helpful as he also reached out to Kyocera Support once I provided him my case number with Kyocera. Quite disappointed with Kyocera for sure. Regret buying this phone and only had it for about a month.
