<v ->In this section of the course, we're going to talk all</v>



2

00:00:03.030 --> 00:00:05.310

about how to troubleshoot mobile devices



3

00:00:05.310 --> 00:00:08.220

including mobile power issues, mobile hardware issues,



4

00:00:08.220 --> 00:00:10.980

mobile display issues, mobile connectivity issues



5

00:00:10.980 --> 00:00:12.840

and mobile malware infections.



6

00:00:12.840 --> 00:00:15.000

So as we move into this section,



7

00:00:15.000 --> 00:00:17.550

we're again going to be focused on domain five,



8

00:00:17.550 --> 00:00:19.260

hardware and network troubleshooting



9

00:00:19.260 --> 00:00:22.080

as we fully cover objective 5.5.



10

00:00:22.080 --> 00:00:25.080

Objective 5.5 states that given a scenario,



11

00:00:25.080 --> 00:00:27.120

you must be able to troubleshoot common issues



12

00:00:27.120 --> 00:00:28.710

with mobile devices.



13

00:00:28.710 --> 00:00:31.350

As we begin this section, we're going to first take a look



14

00:00:31.350 --> 00:00:33.060

at the different mobile power issues



15

00:00:33.060 --> 00:00:34.320

that you might come across,



16

00:00:34.320 --> 00:00:36.300

including things like poor battery health,



17

00:00:36.300 --> 00:00:38.940

swollen batteries, and improper charging.



18

00:00:38.940 --> 00:00:39.773

Then we'll move



19

00:00:39.773 --> 00:00:42.840

into some different mobile hardware issues like overheating,



20

00:00:42.840 --> 00:00:45.720

liquid damage, and physically damaged ports.



21

00:00:45.720 --> 00:00:46.740

Next we'll move



22

00:00:46.740 --> 00:00:49.080

into our discussion of mobile display issues



23

00:00:49.080 --> 00:00:51.840

things like broken screens, digitizer issues



24

00:00:51.840 --> 00:00:55.080

and cursor drift, or touchscreen calibration issues.



25

00:00:55.080 --> 00:00:57.420

After that, we're going to cover some issues associated



26

00:00:57.420 --> 00:00:58.920

with mobile connectivity.



27

00:00:58.920 --> 00:01:01.860

This includes poor, limited or no connectivity



28

00:01:01.860 --> 00:01:03.270

that's caused by faulty cellular



29

00:01:03.270 --> 00:01:06.300

or wireless transceiver and misconfigurations.



30

00:01:06.300 --> 00:01:09.780

Finally, we'll cover mobile malware infections, their causes



31

00:01:09.780 --> 00:01:13.050

and how to rectify them on uninfected mobile device.



32

00:01:13.050 --> 00:01:15.090

Now as you're going to learn in this section of the course,



33

00:01:15.090 --> 00:01:17.700

there are lots of potential mobile device issues



34

00:01:17.700 --> 00:01:20.160

that you're going to be asked to fix as a technician.



35

00:01:20.160 --> 00:01:22.230

So let's get started with our coverage



36

00:01:22.230 --> 00:01:24.090

of how to troubleshoot mobile device issues



37

00:01:24.090 --> 00:01:25.590

in this section of the course.
