I had been using large mobiles for a long time. The largest was the Surface Duo. Great concept "device" but definitely not a phone. Make phone calls is very clunky and unreliable and I do not see that changing. When they came out with the Duo 2 and I saw it was even bigger than Duo 1, I was convinced it was time for a change. So I went in complete reverse and started looking at a small device. I wanted something small and reliable that did two things really well, taking pictures and making phone calls. The Z Fold 3 is everything I wanted and more. Half the time I never even open the phone. I just use the small front screen to answer and place calls as well as answer short texts. I am one week in and loving this phone. I kept the duo to use over wifi but honestly, haven’t even powered it on on the last 3 days. I signed up for the Android 12 beta and am awaiting it to be sent.
