Thank you BSAGREG. The headline is clickbait.
I bought an unlocked GSM Moto e4 ~6 weeks ago for $100 from Walmart. Battery life is better than expected (>24 hours on standby). The camera is "OK" but I knew that going in. Voice quality on calls is better than expected. I don't play games on phones, and performance is excellent — better than either of my Android tablets.
The only problem I have had is that with a memory card installed (in order to offload as much as possible to external storage) it's unstable, and reboots frequently when it's not plugged in or in motion, such as on my body. This instability has been confirmed by Motorola support, and the "fix" is to remove the memory card.
It is using 8.83 gb of internal storage, and 3.93 external, for 12.75 gb total, so in theory it would still have sufficient free space if I removed the card. I'm going to watch space utilization before taking any action, as the instability is inconvenient, but not disruptive.
On average, I make 1-2 phone calls a week, so the Moto e4 far exceeds my basic requirements. For $100, I am satisfied.
