Leslie flashed a CyanogenMod 10 (CM10) nightly build on my LG Optimus Black (Thanks, Les!). HUGE improvement! I previously said “it’s a little bit laggy due to the low-end specs as well as all those virtual machinery and hardware abstraction layers”. Scrap that! The lagginess, it seems, was due to the Android version (Android 2.2 Frozen Yogurt and later Android 2.3 Gingerbread) and the LG Touch UI. With CM10, which was based on Android 4.1 Jelly Bean, everything was snappier. There’s a fair bit of instability (hangs mainly, this is a nightly build after all) but it’s quite usable. Looks like this phone can go on as test phone for another year. Maybe I could even use it as secondary/backup phone.
