contact manager has stopped

"Hi,

I had this problem with my A6000. The contact manager was going very slow and my phone would, at times, not wake up from the sleep mode. This used to happen even when I get incoming calls.

I realized that the problem was happening particularly when I was connected to the Net and was using Whatsapp. After lots of hair splitting and frustration, thought of deleting the cache and data of Whatsapp. This worked !!! Phone works perfectly now.

"Hello Rajesh Rajan,

There are so many reason to occur the issue you mentioned

1) Virus/ malware infection

2) Contact database corrupted

3) Due to 3rd party application which share your address book such as Viber, line ets..

4) Sim card contact memory location having issue with data filed

5) recently you imported contact complicating or address book limit exceeded

Simply you can reset the device and most probably fault will be fixed but before reset the phone make sure all contact backup to the your google account.

Hope this answer help you!

Thanks"

"Hi everyone,

I purchased k4 note and in 10 days I started getting this error message 'contact manager not responding'. But I am not facing this issue for now and would like to share what I did and hope that those who are facing this problem might get a resolution.

I removed the mem card and switched on my cell and I realised that my contact manager started working fine.

I put the mem card in a card reader and attached it to my PC. I found a file named ' conatacts001' and I remembered that I had shifted my contacts to mem card to ensure I have all my contacts in K4.

However, I had also realised that I had 500 contacts in mem card n 500 in my normal contacts. So K4 took time to read 1000 contacts and that's why my contact manager did not respond.

I deleted contacts from my mem card and it's been more then 10 hrs now and I have not faced that issue.

So if someone wants to try this please go ahead and I hope it works for all those who are facing this problem :)"
