爆料人冰宇宙在 Twitter/X 上傳了一部短片，將三星 Galaxy Z Fold7 與 Honor Magic V5 的實機對比，有趣的是，Honor Magic V5 官方數據顯示展開厚度為 4.1mm 折疊 8.8mm，比 Z Fold7 的 4.2mm/8.9mm 還要薄，實際對比後卻出現 Z Fold7 其實比 Magic V5 薄的情形。
There is no accurate measuring tool, but we can still draw a rigorous conclusion: Galaxy Z Fold7 is the thinnest folding mobile phone in the world.

I switched the positions of two mobile phones during the test, and the results remained the same, which showed that the factors of… pic.twitter.com/irlNgKOtH0
早前冰宇宙也拿了 Magic V5 與小米 MIX Fold4、OPPO Find N5、vivo Fold5 以及 Galaxy Z Fold7 一同比較，結果 Magic V5 的厚度與 OPPO Find N5 最為接近，而 Find N5 的厚度則是 4.21mm/8.93mm。
I compared the thickness of all the latest large foldable phones I have—Xiaomi MIX Fold4, OPPO Find N5, vivo X Fold5, Honor Magic V5, and Samsung Galaxy Z Fold7—using universal gravitation. Which one is the thinnest? Someone’s lying. pic.twitter.com/uhsdgSG1xg

對於這不尋常的結果，冰宇宙也拿出了專業的尺規進行測量，有意思的是兩家廠商的厚度資料都不與實測不符，三星 Galaxy Z Fold7 摺疊後測量結果為 8.79mm，比官方公布的還要薄 0.1mm，而Honor Magic V5 則來到了 8.95mm，也確實與 OPPO Find N5 差不多。
It seems that I can only take out my ruler, helpless. People only believe in numbers, but not in the laws of physics.😓

But I still want to wait until the micrometer arrives to measure again, because that is more accurate. pic.twitter.com/ZYRJf5wpGh
其實手機生產時難免會產生公差，造成實際數據與規格有出入的狀況，Honor在 Magic V5 的介紹頁中，也就註明了機身最薄數據僅限象牙白版本，而實際厚度可能會因為製程、規格以及測量方式有所出入。
