Samsung Galaxy S4 Contacts app crashes, entries duplicated, names & numbers altered after lollipop update

After the roll out of Android 5 lollipop update for the Samsung Galaxy S4, we started receiving a lot of problems or questions. Some reported to have been prompted with the error message, “Unfortunately, Contacts has stopped,” others said some of their contacts already have duplicates. There were also others who reported that their contacts list was totally altered or messed up. According to them, the names were changed for some contacts.


Reports that they were experiencing sync issues were also rampant, although, there is always a possibility that it has something to do with internet connectivity. But still, we find it necessary to provide support to our readers who spent time contacting us.

“Unfortunately, Contacts has stopped” error

Problem: I recently updated my Samsung Galaxy S4 to lollipop and immediately after that, when I tried calling somebody, I got the error message “Unfortunately, Contacts has stopped.” Since I bought the phone last year, this is the first time I ever encountered a problem and it surprises me. I already tried updating my phone a few times but it never occurred before. Frankly speaking, I don’t know what to do because I really am not a tech person. That’s why I am hoping you guys would respond to my email and help me figure out what is wrong with it and how I can fix it. Please help me. — Joanna

Troubleshooting: Hello Joanna. You said the error popped up when you tried calling someone. So, basically, the error is triggered by the phone app that’s trying to access the Contacts app. The first thing I want you to do is clear the cache and data of the Dialer (Phone app). Don’t worry, none of your data will be lost but the call logs.

  1. From any Home screen, tap the Menu key.
  2. Tap Settings.
  3. Tap the More tab.
  4. Tap Application manager.
  5. Swipe left or right to go to the All tab.
  6. Scroll to and tap Dialer.
  7. Tap Clear cache.
  8. Tap Clear data, then OK.

The dialer app is the first we want to troubleshoot because it’s the app you were using directly when the error popped up. If the procedure above didn’t fix the problem, then we will have to go for the Contacts app itself. Just follow the same procedure as above but look for Contacts instead of Dialer, and then do the same thing. If it also failed, then back up your data and perform factory reset; it might be a firmware issue.

Some contacts duplicated after lollipop update

Problem: I have about a thousand contacts saved in my phone and I have them backed up in my online accounts. After the lollipop update, I can see there are contacts that have more than 5 duplicates and the number of contacts in the list grew up to 4 thousand already. I already tried disabling the sync but those contacts remained. I know I can delete them one by one but come on, who wants to do that? Is there a way to delete unwanted contacts all at once? — Kyla

Troubleshooting: Hello Kyla! No, you can’t delete those unwanted contacts all at once, or at least, it’s not that simple. There’s no easy way to deal with all those duplicate contacts. One option is to merge them but the again, you will have to go through finding contacts you want merged and by the sheer number of contacts you have, you may be spend more than a day merging them.

Another option you have is to factory reset your phone and then sync one account to download your contacts to your phone. But you will have to go through the hassle of backing up data your don’t want to lose. It’s up to you which one works for you best.

Names & numbers altered or messed up after the update

Problem: Good afternoon droid guys! There was a notification of an update so I downloaded it and it installed successfully. For once I believe everything went smooth only to find out that many of my contacts have been messed up. For instance, my daughter’s phone number now appears under my husband’s name. The same thing happened to many of my neighbor’s contacts. I really don’t understand why it happened but that’s what I’m seeing here now. How can you fix issues like this? — Mitchel

Troubleshooting: The only way you can fix those contacts is to edit them one by one, which will take so much of your time. The best workaround if you have synced your contacts with your Gmail account or any other online accounts is to clear both Contacts and Contacts Storage services so existing contacts will be cleared. After that, just sync your online account to download contacts to your phone…or, you simply just have to build your contact list from scratch again.

Contacts won’t sync after Android 5 lollipop update

Problem: I finally decided to update my phone to lollipop after I was fed up with the notification that there was an available update. After that, to give my phone a fresh start, I factory reset it. All my contacts are saved in my Gmail account but when I tried to sync my phone after adding the account, the contacts won’t appear. I logged into my account and I can see all my contacts are in there. Why is this happening? How can I make my phone sync my contacts. — Letty

Troubleshooting: Hello Letty. Just make sure syncs are turned on. Go to Settings > Accounts & Sync and double-check if the phone is allowed to sync your contacts. Also, make sure you have an active internet connection. Without it, it is impossible to download your contacts from Google server.

I really don’t have an answer to your question why it’s happening because, in the first place, I don’t exactly know how the phone is setup. However, if all else fails, just export your contacts from your Gmail account and import them over to your phone.

Galaxy S4 shows “Updating contacts list” for hours

Problem: After the recent update rolled out by my carrier, my Galaxy S4 was reset deleting everything inside my phone’s memory including contacts. When I tried opening the contacts, it says “Updating contacts list” so let it sit for an hour thinking the update may last that long. After an hour, it’s still saying the same thing. I have more than 1000 contacts so I thought it takes a few hours to update the list. Well, the phone has been doing that for hours now and I think it’s unusual that the updating of the list isn’t finished yet. Can it be fixed? Help me. — Vince

Related Problem: Hello, I saw an issue similar to mine on a recent post for issues Galaxy S5 users have had after updating to Lollipop. I have the same issue on my S4, but the advice you gave the user didn’t seem to address the root of either of our problems–we cannot access our Contacts at all (so duplicate contact items is not the issue). Instead, the Contacts app (even after clearing cache and data) just says “Updating your contacts” with a circle loading graphic. This message does not eventually disappear and I have been unable to access my contacts ever since updating to Lollipop. Do you have any ideas as to how to fix this issue? Thank you for any help you can provide! — Margo

Troubleshooting: If this issue happens, you have two options: to let the phone update the contacts list, or cancel it for later. If you want to go with updating your contacts, then make sure you have an active internet connection and sync your accounts one after the other so the phone won’t pull down data from different servers all at once. If it does that, it will take so long to update the list and there’s a possibility there will be duplicate contacts. However, if you don’t want to update your contacts list just yet, turn off the sync for your account.
