Unfortunately, Contact Manager Stopped Working on Lenovo S650 Andriod 4.4.2?

I did following but still problem exists;
I moved all contacts to Phone Memory
I deleted cache of Contact Manager
I deleted app data of Contact Manager
Did Factory Reset
I deleted all contacts from SIM/Gmail/Phone etc. And then exported to Phone Memory (Total Contacts: ~500)

Still no luck! It is really really annoying, contact manager often stopped working (~10 times a day) and it takes 15 minutes to start working to normal.

I'm having trouble connecting my PS4 to my pc monitor?

I've been searching all over the internet but can't seem to find anything! I'm trying to connect my PS4 to my pc monitor (which is joined onto the pc, not through wires). But when I connect the HDMI cord and select HDMI in; in the settings it goes black grey continuously. I've got the resolution settings on 1080p for both PS4 and PC. Does anyone have a solution/ other free way of using ps4 on monitor?

New smartphone displays seem weaker in comparison to older ones. How so?

Few months back I bought Lenovo Vibe p1m. It has it's ups and downs, but the main thing that got me is the touchscreen. It is gorilla glass 3 and I find it very vulnerable. Just about every contact with anything tougher than nail and it leaves a scratch. I used to own old Samsung Wave S8500 and I dropped it multiple times on a rocky road throughout the years but not a single little scratch appeared. I just want to understand why this change in durability? I'm amateur concerning this stuff, is it just to make more money by making weak touchscreens or is there a technological reason?

I Have a Lenovo s405 with built in WebCam, but it doesn't work. Does anyone know w to fix this?

I Have a Lenovo s405 with intergraded WebCam, but it doesn't work. If I open lenovo YouCam it says no webcam detected, if you are using an intergraded camera make sure that it is turned on. Same thing when I open the CAMERA tile on start it says connect a camera. I don't know how to "turn it on" and in device manager I don't see any camera or image option so I don't know what to do.

How to get the YouTube app to work on my phone?

I switched from a Galaxy Fame to akl Lenovo A916. The Youtube app would work fine on my Fame, even though the phone was slow. I have uninstalled and reinstalled. I have cleared the cache and I have even downloaded Adobe Flash Player (which didn't work). Whenever I press a video, it will buffer and then say "There was a problem while playing… Touch to retry". Sometimes it will show the ad and then do this. I would really love to get this issue solved as they YouTube app is one of the main things I would like to do with my phone. If you need more information, I will be willing to provide.

All help is appreciated,
Alan.
