Device Help Positive Reviews
AT&T deviceThis app works very fine. Seems to do what size 4 stars. I can recommend this one…..LonewolfbbVersion: 3.218.2
UselessThis app is totally useless. Nothing can be used in anything needs to be fixed. I use Apple Support even though you get charged for it. It’s well worth it. If something needs to be fixed, you make an appointment with the Apple Store if they can fix it by remote. It’s wonderful..Windos 65Version: 3.301.3
Runs IPhone Full Decice DiagnosticsThe iPad version of the device Help. runs a iPhone Full Device Diagnostics. Meaning, device vibrations is the second or third exam or trial run. Since the iPad doesn’t have vibration capabilities. The application cannot continue with the rest of the examinations or trials..@Juan Carlos BautistaVersion: 3.301.3

Device Help Negative Reviews
There are times where this app doesn’t help you at allI can’t count on the many times I’ve had to use this app, in fact it not even an app. You select through different options that best describe the problems that you are facing with your phone and it has you follow a tutorial,sometimes when completed does absolutely nothing. Sometimes the tutorial stops and you have to start all over, taking you to AT&T’s actual website prompting you to sign in ,and then it’s ( We’ve hit a snag, try again later) which is so frustrating, how's an app like this supposed to help? I had to call AT&T because I couldn’t send text messages or receive them and even they couldn’t help me but after 2 minutes after getting off the phone with them everything was fine they probably didn’t want to admit that was an outage or something that had to be fixed on their end.
I wish they would revamp the app. In order for your phone to work properly, you have to call customer service and have them do a reproviision on their end you can’t do it yourself.Stevers 80Version: 3.275.1
Terrible AppThis app is completely useless. It doesn’t help with anything, gives you almost no real information, and honestly there’s zero reason to keep it. The name “Device Help” is almost comedy, because it’s not helping with a thing. It runs a quick test kicks you over to some random website with generic troubleshooting tips and calls it “support.”
On top of all that it gives totally inaccurate information about your device. It told me my battery saver was on even though I never use battery saver. Then it claimed I had burn marks on my screen which I absolutely do not.
Yeah this app is trash. Go ahead and delete it.🚮🚮.Tblock Spin⭐️Version: 3.301.3
First Time UseI tried to use this app for the very 1st time which I downloaded at App Store. I click on it to try and find out why ever since the iOS 26.5 for apple was released I’m having issues with my iPad. So I click on it it it starts flickering then took me back to the App Store for me to download it however I already downloaded the app. Each time I click samething flutters around and back to the App Store for me to download and I can’t because I already have it. I know nothing about this app other than I can’t Los it …..Pathetic.Buzzie71Version: 3.329.3
BadThis app was poorly made. But I think it’s just AT&T’s service in general that’s terrible. There are days when I can’t get a hold of my kids because my messages don’t go through. I go to this app to troubleshoot and the app itself doesn’t load, lags, or times out. Then when it finally does work, you go through all these steps only for the app to take you to the AT&T website for further troubleshooting. It’s frustrating. I don’t have the time..DIReyes10Version: 3.289.0
It’s att so of course it useless ; DI contacted them recently about slow data speeds on my iPad Pro M4. I tried to refresh the SIM. They ran into a snag and then I tried to do a Speedtest and it told me to connect to Wi-Fi when I’m checking the data connection so… Yeah, another absolutely useless hunk of junk from att… any other review on here that says different is a bot. This app has never helped anybody with their device ever. I guarantee that……..HolYMunGdIVERVersion: 3.251.1
JunkThe app is completely junk. Just like the AT&T network. They should be embarrassed by this 3rd world junk they put out for people. Whoever put this b.s. together should be fired immediately! Don’t waste your time with this fake diagnostic if nothing. What it all boils down which they don’t tell you. Is there network is terrible. Now we don’t need an app for that..Lwncuszp57Version: 3.301.3
Waste of timeDid a health check and it says battery saver mode is on but it’s not and att support just gives me the copy and paste answers I can get online which are just common sense and then say to take it to apple. Then try to sell me new services. Not sure why I’m even giving it 2 stars….Someone222dVersion: 3.289.0

In proper cellular data usageWhen I get on the app it continues to always tell me for cellular network connection there will be a dash meaning it’s not saying I’m connected but also not saying I’m not connected. Please fix this soon hopefully it doesn’t involve the esim being unsupported..Hoss7721!Version: 3.187.0
No good!The only feature I could access was the device checkup. The rest of the functions took me to a blank page. I will delete this app. The only thing worse than this app would be calling AT&T User Support!.J4267dfnj34sdaZVersion: 3.115.1
