Seconding what @C44Supra said, perhaps logging here the specs of your currently best-performing motor so the group can help hunt down a replacement, especially once the AliExpress pages disappear. I'm...

@scottbez1 Ok this is starting to make sense. Those look like compressed ferrite material, which will have a lower flux density than the little bar neodymium magnets, and so lower...

> I'd say it's probably hard to determine which type of magnet a motor contains if you don't have a clear visual of it or take it apart. @C44Supra Could...

Or find a motor that uses much smaller neodym magnets than normal? We just want lower flux density per pole, I _think_ it doesn't actually matter what kind of magnet...

Random thought -- is there something out there like old hard drive motors that have a huge surplus second hand market, and this could be redesigned around? I know old...

@scottbez1 Any commonalities in those motors that you've detected? I'm thinking about number of poles/winding configuration, magnet dimensions, DC resistance.....

I have this same issue with the same LCD on Pi 4B, and am in a similar situation as the OP in terms of number of units in distant places....

Hi @6by9, I totally appreciate this isn't a Raspberry Pi org problem, it is a 3rd party vendor problem. There doesn't seem to be any open discussion happening elsewhere online...

I have the ability to de/solder such a chip. I'll ask them if they can send me one or two to test. If the chip looks the same, presumably this...

Quick side note for those curious and need a solution fast: [DFRobot's 5-inch touch display](https://www.dfrobot.com/product-2791.html) does not exhibit this issue, at least according to one short evening of testing in...
