Motorola G6

This phone was a steal at $99 but of course the fulfilment was a nightmare. The order was placed on January 7, 2020 but did not actually arrive until February 14, 2020. This was initially supposed to take 3-6 working days but the fulfillment company Ebuynow was taking orders knowing that they couldn’t fulfill them. To boot they were selectively offering refunds up to 15% for those who complained about their process.

Motorola you need to find a better supplier as they are quite unprofessional.

The phone initially came with:

Android: 9
Build number: PPS29.55-24.

After several official updates and reboots later we are at:

Android: 9
Build number: PPSS29.118-15-11-5
Security patch level: December 1, 2019
