Hi,

I've bought two new displays (from china) on ebay and replaced the broken ones on two of my Wileyfox Swift.
Everything looks fine and basically its working but on both phones I got an issue with the display response time.
It feels kind of laggy. e.g. when unlocking the phone via pattern you can feel and see a difference between another Swift.
Somehow its slower and when e.g. typing "hello" and you press the l to fast its only shown once. Like the cpu usage is to high but it isn't.

From my point of view the displays look like they are original parts (Labels, general look).

I don't think I made a mistake during mounting the components from the broken phone to the new one.

Either I got bad luck and bought replacements of minor quality or, thats why i'm writing here, there is some kind of firmware updates.

The old phones where from 2016 and maybe i need some firmwareupdate.

I'm not talking about recovery image or os image. The issue is on LOS 17.1 the same like on LOS 16.0 or TWRP 3.2.3 or TWRP 3.4.0

What about this thread: https://forum.xda-developers.com/showpost.php?p=66158015&postcount=2

fastboot flash aboot emmc_appsboot.mbn
fastboot flash rpm rpm.mbn
fastboot flash tz tz.mbn
fastboot flash hyp hyp.mbn
fastboot flash modem NON-HLOS.bin
fastboot flash sbl1 sbl1.mbn
fastboot flash splash splash.img

Maybe there is something simlar for flashing the display firmware or something? Where i got the latest stuff mentioned in this thread?

I'm very happy with my Swift up to now but if I can't solve this issue I'll buy a new phone. :(
