Script:
00:00:00.080 in order to test and see if I can use an
00:00:02.159 LG dual screen on another phone I have
00:00:04.799 three different phones from three
00:00:06.319 different brands right here a Samsung a
00:00:08.920 Huawei and last but not least a
00:00:10.880 different model of LG phone starting off
00:00:13.759 with the Samsung S21 it was easy enough
00:00:16.279 to put in the case but it's a little bit
00:00:18.080 smaller than the LG g8x so it doesn't
00:00:20.640 completely fill out the case however the
00:00:22.480 real question is will anything show up
00:00:24.439 on the second display well it doesn't
00:00:26.400 appear that it does as it doesn't
00:00:28.080 immediately start displaying on there
00:00:30.000 like it would be if you plugged in an
00:00:31.400 HDMI device and there doesn't appear to
00:00:33.360 be any buttons you can use to change
00:00:35.440 this however this did trigger the water
00:00:37.520 detection warning notification which
00:00:39.640 really goes to point out that it didn't
00:00:41.239 even realize that something was plugged
00:00:43.000 into to its charging port it just
00:00:44.719 thought it was water moving on to the
00:00:46.800 Huawei P20 Pro this one like the S21
00:00:50.000 doesn't fit the case perfectly however
00:00:52.160 it appears that it doesn't matter as
00:00:54.239 again this one did not start displaying
00:00:56.160 anything on the second screen and the
00:00:58.320 phone gives no sign of recog izing it as
00:01:00.600 a device last but not least we have the
00:01:03.199 LG v40 and this one appears to be the
00:01:05.960 exact same size as the LG g8x as you can
00:01:09.439 see by how perfectly it fits in the case
00:01:12.000 this phone actually did recognize that
00:01:14.000 something was plugged into the port and
00:01:15.960 gave me these options and unfortunately
00:01:18.320 none of these options gave me what I
00:01:20.119 needed to display on the dual screen
00:01:22.520 overall it doesn't appear that there's
00:01:24.119 any way to get other phones to work with
00:01:26.280 the LG dual screen not even other LG
00:01:29.040 phones however however I do believe if
00:01:30.880 you're skilled enough to integrate the
00:01:32.520 pop-up button and needed software into
00:01:34.680 another phone's OS you might just be
00:01:36.720 able to use this on some select phones
