I guess this was out-of-the box the case and all your other devices have no such problems?

Ok, then the issue is hardware driven. Best is to make use of your warranty.

Any feedback on the V1.26 changelog? Is there an improvement in screen contrast?

There are changes on the camera HAL and the GLES libs.

- Oma -

Hi again,

So I finally got around to flashing v1.5 of this rom and I can confirm that the screen contrast is much improved! Still not as good as a true IPS panel (regarding white balance -- appears yellow in comparison to the IPS panel on my iOcean X7), but comes close now regarding the contrast.

Haven't come across any issues with your rom yet -- fast and responsive so far. The camera still sucks but that's not something I care about in a tablet (as oppose to in a phone).

Again, thanks Oma for the hard work you've done.

The following users say thank you to rene13cross for this useful post:

Hello everybody. Does P90HD have the same display model as in Kindle fire hdx 8.9? Or they are just similar, but not the same?

Not sure if its the same model since Amazon dubs their display "HDX" whereas Teclast calls the display in the P90HD "Super Retina".

Unfortunately I've never had a Kindle Fire HDX 8.9" hands-on so I can't comment on whether the displays look the same but I can tell you that (coming from using an IPS display on my iOcean X7 regularly) it is not nearly as good as IPS or PLS in color correction but is still better than pretty much any TN panel.

Maybe someone here who has more knowledge on these matters can tell you for definite.

There is a new hardware revision in the field, called A6K7.

Kernel is york #822, preempt 21. Oct 2014.

For the moment I don't know what the difference is. At least the cam is different.

So pls be careful!
