Can't rate this app anything more than 1 star as I'm unable to login due to error 104. Cant seem to find support either which are both problems that should not exist with such a big company.

Discontinued about 3 years ago for all of you that haven't figured it out yet. Was by far the best caller ID app. Such a shame.

Keeps on saying "incorrect signature." This app really needs to be fixed.

I miss this app

I actually really like this. I often need to look up numbers and addresses on the go and this quickly finds pretty much all I've thrown at it. A few suggestions/requests : dark mode color scheme, ability to view texts recently sent to contact you're viewing (my stock caller and a few others I've tried can do this), the ability to choose which screen opens by default when app is launched.

It's a decent app so far, but i can see two huge improvements: add a white/yellow pages directory (facebook information can be rather limited), and integrate messenger. If this could be done, I could easily knock out three or four of my other apps. I'll be keeping an eye on this one, but not something I'll keep just yet.

Looks like Facebook just shut down this app today. FWIW, Facebook did an absolutely terrible job letting users know about this. I got zero messages or warning this was happening. I just got logged out and when I tried to log back in, I got a "Incorrect signature (104)" error. When trying to log in. The only reason I even knew it was being shut down was because I Googled it.

Great app but it is missing connectivity between apps--especially Facebook apps, which is weird. After updating contacts, linking Facebook pages and updating to my contacts full names, everything is awesome on Facebook Hello. However if you click to send sms, it will open up Facebook Messenger and it still shows the old information that you had just updated. Can't figure out how to sync it out of the Hello account, into phone wide. Otherwise I haven't tried the blocker but the id and search is amazing.

Ok, so I had a scam "you won a free cruise" number I did not answer 2 weeks ago. I verified it was a scammer on the net, so I went to the phone number log and "blocked" it. Got the same scammers spiel today. What do you know? The number matches the blocked phone number that called 2 weeks ago. Can't tell if it is succefully blocking other numbers, but you can tell if it's not blocking.

It's a decent calling application. I like the Facebook profile sync so you know who's calling you. Though it seems like that feature only actually happens one out of 20 callers. The one improvement I want is to not get notified at all that a blocked number has attempted to called me. It may be brief but it will still interrupt any music that's playing and my Moto360 still buzzes.

Cli. B. Mar 23, 2018     

The caller ID is good but I'm incredibly disappointed in how poorly the "Automatically block calls from numbers that have been blocked by a lot of other people." feature has worked out. I get a fair amount of random calls from numbers that have a ton of reports when you google them but not a single one has been blocked by Hello. Update: downgraded to 1 star because the app is so inadequate Update 2: it seems clear that this is a vehicle for Facebook to collect data

Every time I create a contact and save and when I go to look them up the contacts are gone. Please fix this issue I like this app.

Rya. K. Apr 2, 2016     

Seems an overall decent and helpful app, as long as you don't mind Facebook collecting your call history usage. I haven't had any technical issues so far. More syncing options with your Contacts accounts would be nice.

Moh. T. May 13, 2016     

The numbers shown are scrambled long numeric strings, and they do not make sense at all

This app does REJECT CALLS set to be Blocked to your Voicemail. If You go Into Your Phone's Call Forwarding settings and Just the line for Forward when busy then click turn off if you can then you wont receive anymore voicemails or ringing of your device by #'s on your devices Internal Reject List or by any 3rd party Call Blocker App you have installed. Blocked # Callers will get 3 rings then a busy signal always when they are blocked and cannot notify you via Call Waiting when Calling you if you are on a incomming call or a outgoing call just straight to the 3 rings then busy. by the way if you are on a incomming call or a outgoing call then someone calls you via call waiting that isnt blocked and you keep the caller on call waiting then anyone no matter what will get the 3 rings then busy signal because there is no way to change this. Only way you iknow a blocked number Tried to reach you is because their # and times tried calling you left in your devices Call Log which is easily deleted. Use Zoner Antivirus As Your Blocker of choice to block people not in your android contact instead of Hello if you want only contacts to contac t you.
