With ‘rugged’ smartphones like from Oukitel, Blackview, Ulefone, Cat, etc., can it be expected that internal damage like to speakers or microphones be repaired and put back together without losing the IP68+ rating? Or are they generally sealed tight so that opening them is not an option in the first place?
[object Object], I’ve never worked on any of those phones personally, but I saw a video of a guy testing the “ruggedness” of one of the CATs. Turned out (after rigorous testing) that the IP68 part was… questionable, to say the least. Water had easily gotten in (the phone was brand new, taken straight from the box, to the test) even after only a few minutes (but very thorough) exposure.
