–Replaced hearing aid batteries around 9 AM.
–Installed large grouphead and new solenoid on Livietta. Solenoid made no difference whatsoever. Tried 18 grams of coffee in larger portafilter: no go. Had to remove some to get the portafilter in. The pull was kind of messy. Hard to imagine I can only add (about) 2 grams when going from a 49mm to a 54mm portafilter. [edit] Turns out I likely have a single or double basket, which might only be good for 14 grams. Just ordered a La San Marco triple basket, allegedly good for 21 grams (though probably not on this machine). Should be better, anyway.
–Samsung Galaxy Z Flip came in. Great ergonomics. Sound on a call with Grace was no better than iPhone. Trying to eliminate all unwanted apps and such, then add the GOODEV volume increaser. It currently seems to be stuck in an infinite loop of Android system updates. [edit] Finally stopped updating. Got the GOODEV app and tried it out. Not too impressive.
