Hi Amir, and thanks for the review, its really pertinent.
I totally get your gripes..I sorely miss the days of memory expandable, capable headphone out flagship phones, when a 6"1 on a 16:9 ratio would display more usefull content than todays slimmed proportioned 6,7". They are a pain to pocket, too tall to operate confortably with one hand, and only a 6,8 or 6,9" gives me the screen width I find confortable and natural to read on as I do a lot of it.
I thought this was going to be a quick fad, but its taking its time to wane.
Had an Experia ZX3 before my current Sammy S21 ultra...Loved it, was a probably the best manufactured piece of machinery I have ever seen, almost alien in sleekness ( that extra hard curvy black glass back was something, so polished it would creep away with the slightest surface tilt), but this S21 runs circles around it, espc.in the camera. That Sony had the latest, best sensor at the time, but Samsungs and Apples of the day left it in the dirt for pictures.
Audio output is good sounding and manageable with Samsungs USB C to 3,5 mm jack converter driving my Drop 650 ( wavelet app can get me a couple of much needed dbs in preamp gain), but LDAC on the Sony was great, as I mostly use my Sony Wireless XM4 buds anyway.
All in all, it is not strange that cellphone wise Sony is where it is...so many bad calls, its chilling. Would hate to see them go the way of the LG..
