Hey, I have got a Note 4 SM-N910F, with many bugs on the official firmware.
On 4.4.4 I had problems with the keyboard, sometimes it lagged or did not respond as quick as it should.
I am facing also random lags when browsing through the app drawer or the homescreen, as well as scrolling in the browsers is very laggy.
Youtube, or video media in general are lagging, it's no fun to watch a clip on the phone.
The biggest problem is the wifi.
When I try to activate the wifi it takes up to 20 seconds till it's turned on and when i turn the wifi off and turn it on again, the phone forgets all the wifi connection i set up.
The fingerprint sensor isn't working as well.
Also after I updated the phone to 5.0.1 the issues were still there, nothing changed.
I have tried a custom rom just to be sure whether it's a hardware problem or just an issue in the software.
I flashed the unofficial CM 12 rom: it worked perfect.
No lags, no wifi problems.
I have been using the Exynos version SM-N910C before on 4.4.4 and it worked perfect and very smooth.
Please help, i have tried everything and nothing worked for me.
I did tons of factory resets and re-flashed the firmware, nothing helped.
Same issues.
I would be very happy if someone could help me, I'd like to have the same experience as I had before on the Exynos Note 4.
