I don't know, but when I've used devices with temporal dithering (e.g. macbooks) on e-ink screens the results have been very poor. Until it's switched off.
The optimisation on the Hibreak Pro is excellent, so I doubt this is an issue. They claim it is 'zero flicker'.
Clokwork Considering the device is Play Protect certified, what additional security concerns would there be if only using Play Store apps?
I’m not an expert on this, but I’ve seen comments suggesting that with Play certification, the CCP security risk is lower than that of the routers and networks the device connects through.
Security is good, but be realistic too.. The Chinese don't care about nobodies like us. Americans however, would add all of us to their databases.
But online comments warning of the security perils of fully Chinese devices are much more common, compared to all the other devices that are still assembled in China but fronted by Western companies. I also don't think CCP care about any of the data that would be on my device. But American companies want to mine that data much more. To be honest I don't really care about that much either outside of authentication and transactions.
Still on e-ink. Using a Hisense A9 these days. Faster than the older Hisense e-ink models and XDA got way more involved so it can run a range of systems rather than just root and add GApps.
Pity the next model with Kaleido 3 colour never came out.
I don't find using B/W that much of an issue, but would like a good small screen that doesn't trigger me too much to cast to for colour when I need it. Tried one that was meant to be flicker free, etc. and sent it back very quickly.
For anyone interested in the Realme 9 Pro 5g that lives in the US: I had previously been using the Realme 9 Pro 5g, but a couple months ago the cell service and mobile data started acting really funny. I called Mint Mobile and they said my phone is no longer compatible because my phone doesn't support one of the key bands (I don't remember which one). I tried a bunch of carriers (both AT&T and T-Mobile), but I could not find one that works. So, if you live in the U.S., you probably want to avoid this phone.
I recently bought a Moto G Power 5g 2024 and I'm really happy with it. No headaches/nausea/tinnitus.
Here's the waveform using the Thorlabs PDA100A2. I went to a couple different stores (Best Buy and Microcenter) and tested about 50 phones and this was the best Android phone (i.e., lowest flickering) I could find.
No PWM at any brightness level.
There were a couple iPhones with a relatively smooth waveform (iPhone SE 3rd Gen and iPhone XR 4G), but I prefer an Android so I didn't look too closely at those.
