This was the first time I had ever used a Motorola phone since the flip phones of the early 2000's. In a world of specs and boring devices, this one was a blast to use! I could respond to texts on the small front screen and with googles voice to text I just had to press the microphone button and speak my text and then shoot it off with a few clicks all without having to open the device. It was quite refreshing to use a device that felt so much smaller, but yet still had the bigger display if I wanted it. I was sad when I had to return the device, but I will be waiting for a sale to purchase the new Moto Razr+ 2024 model. For testing purposes I only tested the interior display and not the external small display. I figured the inside one is the one that will get the most usage and time spend on it, therefore the highest impact to the eyes. Motorola is one of the few companies that actually does realize PWM impacts people and makes settings in their device to reduce flicker.
Motorola's software includes a "flicker reduction" setting. As you can see it actually is doing something. With it off you can see a high modulation depth of 99% at 75% brightness but with a higher frequency rate. While the frequency depth is pretty bad, the flicker rate is almost twice of what apple and samsungs is (thats a good thing) and this is with the flicker reduction off. When the flicker reduction is turned on you see that modulation depth change to a sort of DC dimming pattern. You have to look at the modulation chart on the right to see what I mean - most of the modulation stays within the timeframe with a dip here and there (which is probably the opple light master picking up the refresh rate of the device.). While the chart shows as in the risk area, I beleive it is not, and a miss reading by the opple device.
As we dim the screen to 50% we can see that even with the flicker reduction off the device starts to go into a flicker reduction mode. We have a 44% modulation (again seeing that refresh rate dips, so the actual modulation is more likely at 10-15% which is quite good. We are also seeing the frequency of 123 which more likely corresponds to the refresh rate of the display (120hz). It looks more like dc dimming which is much better for the eyes.
At the lower setting of 25% brightness we see the benefit of having flicker reduction turned on. You can see that with it off we have a higher frequency rate of 744hz (again twice the iphone), but with a really high modulation rate of 99.5% which is harder on the eyes. If we switch the flicker reduction setting on we get dc dimming with a really low modulation rate around 10% and a flicker rate which more correlates to the refresh rate of the device. Overall I can highly recommend this device. Not only is it fun and refreshing to use, but it's also very easy on the eyes. If you want to pick a flip or folding device and are concerned about your eyes, this is the one to get, you won't regret it.
