I just got two E4 with version 2.3 from ebay. One is already cracked and one is not cracked. But I found that they all have the same problem
,
The measurement function is normal after cold start. However, I need to press the power key twice In the hot start, after the first press, the LOGO appears for about 2 seconds, then the screen is closed, the device does not boot, and after the second press, the LOGO appears again. The device is boot normally and the measurement function is normal.
the two e4 (cracked and uncracked) has the same problem,Is this a common problem with version 2.3?
The cracked E4, after pressing the power button for the second time, sometimes does not measure normally. Sometimes there are only visible light images. Sometimes the thermal image is a green screen, and sometimes the thermal image is a large gray square. Is it caused by a failed crack?
can someone help me ?thanks!
