I just picked mine up 3 days ago.. and so far, I love it.. very fast, no bloatware in the OS and very fluid..
Camera is fantastic but images can be a little noisy (grainy) at twilight.. I have noticed that sometimes if your trying to get a blurred background and trying to take a subject / object in foreground... it can sometimes get things confused... and Blur out your subject, and focus on the background... so check your images after shooting, but this is minor as its truely a great camera... In fact, I think the XL camera beats the Galaxy S8 / Xperia XZ Premium and is on Par with the G6 and even the new Xperia XZ2.
Single bottom Speaker on the XL is better than the smaller Pixel, due to the bigger body mass of the XL, however.. default ringtones are very quiet on the phone, so download or use your own... Its actually a very good speaker, especially for Podcasts.. and it has a 3.5mm jack (yay).
Voice calls are very clear and crisp.. and the ear piece can get quite loud
As of yet, Ive only had it do 2 battery cycles, so I cant comment... but it appears pretty good... standby / sleep time is awesome..
Fingerprint scanner is very fast and reliable and never had it fail yet, unlike my old XZ Premium... which hardly ever worked..
This is a great phone in 2018 and an awesome bargin.. You cant go wrong..
Enjoy it.
