@All: I have a question: Regarding Software and binary support for Linux (Let's put performance aside), Is MTK better than Qualcomm? I heard MTK has a better support for Linux than Qualcomm, but I couldn't find evidence supporting it...

But yeah, everything I ever heard about MTK was that the driver support sucks.

@British Thank you. The last step always be the most difficult.

From SailfishOS perspective, Qualcomm is just more explored, with own quirks and so on. libhybris can work with MediaTek as well (Ubuntu phones and tablet), so I think you can choose chipset based on availability/price.

They dont use standard android APIs so passthrough is broken, 4k youtube is a mess...... Few updates later ATV1 platform is still on MM with all the bugs thet were there with first MM based FW. Meanwhile ATV2 platform did recive nougat update but the same things are broken there also. Happy reading https://github.com/CiNcH83/sony_atv/...ssue+is%3Aopen
Please elaborate? I'd like to understand why
So if they can't get their shite together on a 1000+€ devices with just two SoCs in use across all manufacturers then what can you expect from phones. The first thing I look in the phone is not to be based on mediacrap SoC.

- While Mer & libhybris (being the base of SailfishOS) theoretically support MediaTek SoCs too, all ARM-based devices running SailfishOS well (e.g. the officialy supported ones) use Qualcomm SoCs.
- Qualcomm has a bit of an Open Source strategy (currently mostly just covering their Adreno GPUs, i.e. handing out technical documentation under NDA to FOSS developers), while MediaTek has nothing.
- MediaTek uses Mali- (by ARM) or PowerVR-GPUs, which both have no Open Source driver development at all (the Lima initiative stalled years ago, right after its start).
- Qualcomm is technologically more advanced (utilised semiconductor process nodes etc.), resulting in better performance and runtime (i.e. using less power).
- When building a niche product, IMO one should try to use components as mainstream as possible; otherwise that becomes even harder.

Okay Thanks... I asked the question for the hope of having native GNU/Lunix without Libhybris. But if not possible I will stick with Qualcomm...

And a MediaTek SoC will not get you closer to this goal, rather the opposite.
You once stated that you are going to alter an existing design based on a Qualcomm SoC, which is absolutely reasonable.
If you have a choice, picking a design with a Snapdragon 650 (as in the Xperia X) or at least one with a Snapdragon 65x will significantly raise the probability of proper SailfishOS support.
As we already discussed here, a plain GNU/Linux without touch-capable applications is pretty much useless on a smartphone (and one cannot use the internal modem for calls and internet access, currently).
Please stay away from the idea of providing any software adaptations beyond boot-loader and maybe kernel, while trying to minimise the latter (kernel adaptations) as much as possible.
Do estimate these software efforts to be larger than the hardware redesign (people usually underestimate this by at least a magnitude, i.e. more than factor 10)!
