Hello,
Despite some software fixes for the screen backlight flicker on PinePhone, the primary issue remains, meaning that the intensity of screen backlight changes somewhat erratically and very annoyingly when there's communication on the internal I2C bus, such as when the operating system talks to the LTE modem, or when the total power draw of the phone changes significantly, for example when scrolling the screen contents.
I've already researched the possible ways for fixing the flicker by doing some hardware modifications, and I've reached the point where I'd need to secure a development platform. In other words, I'd need a development PinePhone, which would be used for trying out hardware modifications. My goal would be to end up with hardware modifications and clear instructions that are as simple as possible, and easily doable by many PinePhone owners.
Understandingly, I do not want to try out those hardware modifications on my own PinePhone, because there's always a chance for the electronics to produce a puff of magic smoke.
Thus, I'm asking for a way to get a PCB 1.2b PinePhone, for the above-described development purposes. Ideally, I would like to get an additional, separate PCBA 1.2b board, in case something bad happens to the original board. Also, please, keep in mind that I cannot guarantee that the whole endeavour will actually result in the desired hardware fix, but I would do my best.
Finally, there are two questions:
1. Would the Pine64 team be willing to donate the required hardware?
2. If not, would the forum members be willing to pitch in? I can accept PayPal payments.
Any help would be appreciated!
