Is using native 4k safe?

[HermesHidayat]

So i have been using native 4k(2160x3840 with 820 density) for a while. And i noticed that when the temperature of the phone rises around 40 degrees Celsius  the keyboard kinda stutter thus i miss a few letters...

If i let the phone cooldown to below 35 degrees Celsius everything will be fine again. Was wondering is it just me or is everyone using 2160x3840 having the same issues too?

I use swiftkey keyboard...

@HermesHidayat you're using the phone in a way that it wasn't intended to be used so there's no guarantee about its performance or stability.

Performance wise. Nothing is wrong. Stability wise, just the keyboard lags... So i was trying to find out a solution...

Hi @HermesHidayat,

I have to preface this with @najodleglejszy is correct. When using a device in an unintented way we cannot guarantee the functionality.

That said, have you tried using another keyboard to see if you get any better performance out of it?

[HermesHidayat]

I tried Fleksy and Google Keyboard but it seems the same...

But it only happens with keyboard. Like in whatsapp or chrome.

And i realise that it lags more in 1890x3360 compared to 2160x3840...

And about unintended isnt Adreno 540 capable of 4K HDR at 60fps output display? i read it somewhere but i forgot where...
