Are you still using it as your daily phone? If yes, which custom rom/android version are you running? and is it still usable?

I was using it as my only phone with the stock OS up until mid 2018 when it started having what looked like hardware issues - like, sometimes the phone wouldn't ring but I got the missed call notification seconds later. It still had around 1 - 1.5 days of battery life at the time, with the original battery.
