    Title says it all. Is there a suite of tests to run to check function, screen, hissing, et cetera?

    Simple if it's a At&t or T-Mobile Version it's a dud because it has a Intel 3x3 Mimo Radio and Not a CDMA Verizon Qualcomm 4x4 Mimo Radio which is probably why so many people are saying they are getting worse reception than the 6s. Intels first GSM Radio is a failure.

    So that's how you tell it's a dud.

    I have a Verizon 7 plus and my reception sucks and the LTE drops off.

    Did Intel supply every 7 GSM with their radio technology? Also makes me wonder why Apple would go with 3x3 instead of 4x4 for the GSM model, if true

    Use the phone the way you normally use it and see if it works to your liking?

    Update Your Service do a PRL Update or take it to a Verizon Corporate store and have them Hot a certain set of keys that gets them to the carrier service menu, and Update from there. It's a brand new phones it may take the towers a while to be optimized. But all in all my iPhone 7 Plus gets reception in places my Note 5 had none And unfortunately for my friend from work his T-Mobile GSM model with the Intel 3x3 Mimo Radio gets zero reception in places.

    Yes and Intel wants to cozy up to Apple big time they probably give them the Radio chipsets for a loss. Which is a profit to Apple. And expensive component for free.

    Second part is why ? Apples A9X and Now 10 Fusion are Faster CPUs than some Intel Core M CPUs and Some Older Core i5 CPUs
    So Intel wants to be a CPU supplier like Samsung like TSMC like Qualcomm Intel sees CPUs eveolving away from the Desktop and needs to get in the fight.

    I expect Apples Next iPad Pro Update in 2017 to Feature Intel CPUs and Radios
    IMO that's a Mistake for Apple because it discredits their own Amazing CPUs and makes people look at Intel again as superior.

    The PRL update doesn't work on 4G phones it says, won't even let me dial it.

    I'll hit the Verizon company store tomorrow and see what they say. This is crazy that Apple puts a new phone out that cell company's aren't prepared for, unless its Apple not working with them.

    Apple tells them the Specs sends them a few final devices for the Engineers at Verizon but that's it. It's up to the Carrier to make sure the Devices works on the Network.

    CDMA carriers have it easy CDMA IPhone 7 Plus uses the Exact same Radio that the Galaxy S7 uses it's a Qualcomm X12 Radio Qualcomm just makes the parts and sell it to Apple and Samsung.

    Simply no excuse for Verizon not to be ready.

    What I do with the Apple Watch is I perform a "water stress test," in which I place it in a glass of water for 20 minutes or so to rule out defective seal. However, Apple is allegedly refusing to warranty water damage in the iPhone 7/7+ even if it's caused by a manufacturing defect.

    Here's one suggestion. I'd enable 4K video in Settings, then find a very quiet room and place the phone down on a flat surface and record 30 seconds of video. When you play it back, listen for popping, clicking or buzzing noises. You're also going to hear some hissing/roaring white noise, which IMO is not an issue at this time. The pop/click/buzz noises are probably ICs making noise under load and Apple seems to be (correctly) treating them as a defect.

    Any proof of this? I've heard lots of speculation about the Intel vs. Qualcomm models, but so far it seem to be only speculation. The only widespread problems reported on this forum (or anywhere else I've seen) seem to be with the Qualcomm versions on Verizon's network, but that may well be a network problem, not a modem problem. FWIW, I have an Intel iPhone 7 on AT&T and have noticed no differences in performance from my 6s+ that was on AT&T.
