Best App. It can even get your phone into charging mode if the problem is that even though the "power consumer" is properly connected to the"power supplier", it's still not getting into charging mode. If you run the app, click on the problematic USB device, tap the diagnostic report, wait for the app to load the permission popup, tap Use by default for this app, wait for the app to complete the diagnosing process, then you will see that, after a few seconds, the phone/tablet starts charging.
UPDATE: Was able to get app to work on headphone dongle - it required media be actively played before the app could detect it. Galaxy note 20 ultra- app did not detect attached usb device (headphone dongle with active electronics in it (D to A converter). Tried a few different ways, no results. The full page ads oyhers have disliked did not bother me, considering the nature of the app (one would use it infrequently, only for short lengths of time, can tolerate some intrusive ads in that case)
Had trouble detecting a USB connection to a printer, this app sorted it straight away. Ads are annoying but not a great problem. Easy to use and just the job for my requirements.
App works wonderfully. With this app I was able to diagnose and correct all issues with USB-C headphones and peripherals. Without this app the frustration of connecting usb headphones could be enough to make a person curb stomp a phone. This app should have a paid option to be rid of ads.
Works well, but would be better if ads were only shown before closing the app.
It tells you have an usb connected. Expected to be able to fix or format it. A lot of add, yes
First time I used it-it opened detected a usb port and asked if I wanted to run diagnostics. I did, it froze, and then the app wouldn't reopen.
Great app but the intrusive ads make it almost unusable. Every action involves a full screen unskipable ad with jarring audio.
Did not detect my Sony USB Audio DAC dongle. I cant give it fair review if right off the bat it wont do that. Has pop-up adds after every "detect" attempt.
I wanted to identify if my USB is still fat32 or ntfs after formatting it. App does not show this info. Ads are also annoying. Avoid.
Good app. Helped me with a usb which showed that it was corrupt but was working fine on pc. After i used this app, usb easily connected
Detected my centrance micport pro2 on oppo ax7 after I enabled OTG in phone Settings, which helped me prove my cable is good. Thank you!
"All devices" does not include chargers or power transfers to or from other devices. It should say except power.
if u have any otg mass storage /pendrive related problem jst open the app find ur device and click on diagnose and that's it..... boom......ur prndrive is connected to ur phone
Diagnostic does nothing about billboard devices; Otherwise doesn't seem to do anything that equivalent ad-less apps don't do.
Obnoxious Advert Use. Click reload, see ad. Click device, see ad, click back then click another device, see ad. 10 ads in 30 seconds. Garbage.
My phone is a nokia 3.1 and it dosent recgnize my wired controllers but this app does however my phone still wont recognize my controller and i dont know why...
Full screen ads. I shut it down immediately so I wouldn't know if it works.
wonderful app made my type c earphones working again as my phone was not able to detect them as earphones
Doesn't work, says "no devices detected" with my headphones plugged in
Pop-up ad which can't be closed with search semiconductor message
The app didn't detect any devices or attempt to troubleshoot the issue.
Awful won't connect to anything, cant find devices, bad
Quick and simple to use, not much to do on it.
Doesn't work with headphones usb dongle.
nice app can see detail, but too much ads
All my data got erased after diagnostics this app .. 50 gb got erased ..I need to raise complaint aganist ur team ..
unusably full of intrusive ads
Doesn't show USB c power delivery devices. Way to many ads for cat videos youre required to watch just to find out it doesn't work. I hate this fecal material.
