Could a bad charger/adapter damage a mobile phone

I know cheapo and knock-off chargers bought from Wish, or Ebay, or night markets, or whatever. They may not only ruin your phone, they may also ruin you as well, with risks of electric shock and/or fire. Some of them can be absolutely lethal.

Some of them can be seen here.

同志，为何不在淘宝购买，淘宝天猫质量都很好，只要不是便宜的，多半比ebay好，ebay的水分很高

Help Directory of android files

Hadron
USB debugging is performed by a program called "adb", which you install on a computer. You then enable USB debugging on the phone (usually via the hidden "developer options" menu, which you unhide by tapping repeatedly on the "build number" in the software information in the system settings - but it's a long time since I ran Android 4.4 so can't guarantee it was already done there). Then if you connect the phone to a computer via a USB cable and USB debugging is enabled on the phone you can use ADB (Android Debug Bridge) to execute a range of commands on the phone.

The way you do it is by typing adb commands on the command line of your computer. So from the directory you have adb installed in (or from anywhere if you've added that directory to Windows' equivalent of the $PATH, the list of directories that the system looks in when you type a command) you would for example type:

adb devices

which should return the serial number of your phone (probably together with some messages about starting an adb daemon). If it does then adb is working, if not you should try to work out why not.

Then you can get it to list the contents of a directory by typing

adb shell ls directory

where the "directory" should be specified using a unix-like format (i.e. "/" rather than "\" between subdirectories). You need to use unix formatting for the directory path because this command is being sent to the android device, and android is based on the linux kernel. The syntax of this command is: "adb" (the program that talks to your phone) "shell" (execute linux shell command on the phone) "ls directory" (the command you want executed). "ls" is the unix command to list the contents of the specified directory - if I remember DOS correctly the equivalent in Windows would be "dir".

So for example to see the top level of the file system (if it will let you) type

adb shell ls /

or the user-accessible part of the internal storage by typing

adb shell ls /sdcard

or equivalently

adb shell ls /storage/emulated/0

So just put in the path to the directory you want to list the contents of.

Then if I wanted to write the output to a file, rather than just list it on the screen, I would type

adb shell ls directory > myfile.txt

where the ">" is unix shell for "output to the file named here". That's the bit I don't know the Windows equivalent for, but I assume that it exists.

That won't wipe out everything, will it? I've got a lot of stuff I don't want to lose on there. If it works, how do I prevent it from going into fastboot again? There should be some kind of idiotproof (ahem) lock on these things.

its cache which is where temp files go.....no important data will ever be stored there. the only way to lose data is if you wipe data or factory reset the device.

here is some info on cache:

Help Need alternative video wallpaper app

Have you tried using lower resolution videos?

Using videos for such a thing will eat a battery charge up quick.

The higher the resolution, the more useage.

Also, do the videos need to be in .gif format so that they repeat?

I think there would also be a limit as for how long a video may be for this.

You can try this app to reduce the resolution and/or edit the length of the video.

Here is an app to change formats.

Or else you can try this website.

Thanks very much for your help. Battery is not an issue for me when using this app. The issue is solely it's poor performance. As for format, it accepts multiple formats but I'll do some conversions and shrinkages to see if the issue persists.

Where's my phone?

This is unlikely to work.

Why do you say that?
That is how I set up my devices now- I put the apps (apks) I place on all devices onto an SD card, and the first thing I do is install NoRoot Firewall and block everything until I have installed everything else.

This prevents the device from downloading tons of crap like they do when you first get them and turn them on- they can't wait for you to connect to the internet so that all that worthless junk gets downloaded onto the device.
