Check My Device

Do not have black screen to check stuck pixels

Lots of tests ideal for pre sale & pre purchase of a phone. You pick your test from a screen full of tests organised by category. Easy to use for just doing one or two tests if you having trouble with your phone. Or do them all for thorough testing pre purchase. Very similar to other app Test and Check for iPhone but that one you have to do them all in order - skipping ones you don’t want.

Don’t bother Some tests do not work on iPhones Maybe Android, but not iPhones

A few of the tests do not work. Needed app to check Face ID but the test does not work

Don’t bother, this is such an useless app. When I first saw it I thought ‘this will be good to find out about the iPhone I’m about to get’. Needless to say, it doesn’t provide any new information than you already know if you’re in the market for an used iPhone. My advice: do your research and you’ll get much more info than this app will ever provide.

Good, comprehensive battery of manual tests. Too bad some other users don’t grok, dismiss the value. Free is excellent for pre-sale check on someone else’s device. Could be slicker in various ways: 1) automated serial # lookup from prefs, auto-submit to website, display results in app window. 2) Having to go to Photos app for video is goofy. 3) GPS zoom could be finer granularity. 4) could intercept button presses, automatically register. 5) Wish it supported earlier iOS versions. Regardless, worth at least $5. Sorry to see this seems to be abandonware; worth improving, perhaps selling to an iPhone repair outfit.

I tried this app and it had all the possible testing features. They have very accurate results.very happy with this app.Keep up the hard work! 😃
