YOUR Stress test is very useful on toughphone IP certification.
I see your test on nokia and samsung toughphone, but 2 quest:
• first •
for a complete test you should do full test, hardware and software, installed applications, quality of speakers in play, etc… (I really glad for your hardware test, I Search hard for a site like yours)
• second •
On top of my message, I'm writing on your stress-test specifications it's in primary for tough; can you test other commercial though-phone like casio BRIGADE, sonim XP2 SPIRIT etc...
COMPLIMENTS for your site and your work
