Help!! Can not open up messages on Lenovo K3 Note after 6.0 update

Hello. I have just updated my lenovo K3 note. I am having 2 main issues with my newly updated to marshmallow device. When attempting to open up messages, the screen changes to contacts and the screen turns white with only a title that shows ¨Contacts¨ but no edit or add contact button at all. Same problem happens if I attempt to open up phone or the contacts app itself
The second issue is that since the new update, when I reboot the phone, I get the black screen of death. It can be easily resolved for me once I plug it in but sometimes, it just randomly does that and I don't have my charger at all times. I did a complete factory reset after the update in an attempt to fix the black screen of death but it now has caused me more problems
Thank you for an answer

6.0.1 Blank screen on reboot

Just created a pre-rooted rom using nordic combined 23.5.A.0.570_R11D and flashed (locked bootloader method). But I have a couple of issues. One is that a few seconds after the phone boots up the screen goes blank and the only way to get a display again is to press the power button for a few seconds which makes the power menu and the home button appear. I'm then able to press the home button. Only seems to happen after reboot. Anyone else seen this? I didn't for one of the UK based roms as I was worried about bloatware / customisations by Vodafone or Virgin Mobile.
The other issue is with the alarm clock - when the alarm goes off the screen comes on but only shows the background wallpaper. Only way to stop the alarm is to hold power button to get power menu and reboot. I've managed to get around this by removing the 20.1.A.0.12 clock app that came with the rom and installing a 20.0.A.0.28 version from KK.
Hmm after another reboot after repairing the alarm clock with the KitKat version the blank screen's not appearing anymore so perhaps related.
Its hardware problem your screen needs to be replaced same happened on my Z3 D6603 and hopefully the warranty saved me
I flashed 4.4.4 then 5.0.2 but same problem so its not a software issue.
I'm facing the same problem the screen goes blank .Nothing work to fix it .I've flashed the phone with lolipop it goes back normal but after few hours it goes blank again.Any idea guys ?

That's what I thought originally as it had just come back from repair after having the screen fixed but I've not had a problem since removing the clock apk.
Hi all,
I'm having this same issue. I've just updated my D5803 to Marshmallow 6.0.1, build 23.5.A.0.570. Ever since the update, whenever I reboot the phone, it shows a black screen, and I have to press and hold the power button to get the home screen icon to show. And when my alarm goes off, just the wallpaper shows. If I press and hold the power button, I can get back to the home screen, but there is no way to turn the alarm off, I have to reboot the phone - not so fun when I just want to hit snooze!
I find it hard to believe no one else has had this issue before this build was officially released? I'm considering going back to the previous version
Edit: Well, this is interesting. If I take the phone out of its case the alarm works fine, put it back in the case, doesn't work. Take it out, it works. Put it in, doesn't work.
Edit 2: So, I reverted to Lollipop 5.1.1 and the alarm and phone worked perfectly. Updated again to Marshmallow - same problems, black screen and alarm not working while in the case, but alarm works when not in the case. Seems pretty definitive to me that it's a Marshmallow problem!
Bug is still present on .575 update. The strange ting is, on my phone when I disable the smart cover(Settings -> Sound & notification -> Notification access) it stays off, and then the phone is working fine. On my colleagues phone's it's switches itself back on after a call. I have no idea why this is not happening on my phone. Can't find any relevant setting differences.

Wonderful

Screen not appearing as soon as the call is connected.

Hi there,
Whenever there is a call, my phone screen will go blank and unless the caller hangs up, I cannot end the call from my end because the screen does not appear. I have to use the power button to make it come out of the dialer app. I have tried using factory reset but that did not work out. Could anyone take the pains to tell me how to resolve this issue?
