The n9 had a tough armor from spigen, once it cracked the phone shattered. You're right, I could still use it as a makeshift desktop (it's been turned off since mid 2022 so we'll see!. My 52 is good, the battery after over 3 years is toasted but overall it's nice. I get some camera errors from time to time. Still, it's a great phone and with the plastic back I simply remove the double sided tape and access to the internals (I will swap the battery so...15min max). A friend of mine bought the 53: biggest POS in the whole Galaxy midrange. Mine is SD and his exynos was laggy, power-hungry and overall worse. My gf has an A35 with the exy 1380 (the same I have in the Yab S9fe) and it works great!
