It’s poor optimisation, end of story. The lags you speak of, I noticed them within a day or two of getting this garbage. Severe lag on YouTube scrolling. Severe lag on Facebook feed. Severe lag on Amazon review section and so on. Basically if there’s a video (moving item) on screen, or bunch of photos, and you scroll through it, it will lag like crazy. We can’t know to what extent the frame drops, because built in frame counter wrongly reports 120 hz still. But it’s definitely below 60 hz. Ram booster this that are all BS solutions and won’t work as I’ve tried them all.
Funny thing is, if you charge the display refresh rate to Dynamic, instead of High, the lags are slightly less.
This phone in plagued with more bugs than one can imagine. And seeing that there’s no fix for these problems for months now one should clearly understand that this fraud company has no intention of fixing issues. Just sell the bloody thing and move to something else. Basically any phone will be better than this, any.
