[no root] Change screen resolution to increase battery life SM-J7108 and Galaxy On8 - Samsung Galaxy J7 Guides, News, & Discussion

Reason Galaxy On8 is applicable is they got 1080p display
ok, let's get started, first you need Adb. If you don't have, download below:
https://developer.android.com/studio/releases/platform-tools.html <-- that package about 7mb
Extract it to a folder, on that folder Shift + Right Click, 'Open command window here'
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
1. Enable USB debugging (google it)
2. Run this command:
adb shell wm size 720x1280 && adb shell wm density "320" && adb reboot
3. Done. Your phone will reboot, voila! Your screen should still look nice without noticeable change
To reset:
adb shell wm size reset && adb shell wm density reset && adb reboot
How I calculate 320, for 720p case:
default is 480 so 480 รท 3 = 160 then 480 - 160 = 320
That's it

Did you tested it in on 8 or any touchwiz rom ??

(Tut) Fix insufficient app storage error

Warning: I am not responsible for any thing happening to you or your phone
This should work on any phone and doesn't require root
1. Download and install Android SDK and Java development kit
2. Start up an elevated command prompt and type in cd C:\Program Files (x86)\Android/android-sdk\platform-tools or if that doesn't work cd C:\Program Files (x86)\Android\platform-tools
3. Make sure USB debugging is on then plug your phone into the computer
4. Go back to your command prompt and type in adb shell pm getInstallLocation then type adb shell pm setInstallLocation 2
5.Reboot. Now hopefully the error should be gone its been working for me so far

[Q] - I9502 can't download nor save file to memory

Hi,
I'm having a problem with my Galaxy S4 Duos I9502, somehow I can't save any file/picture from internet to Download folder, only original app like Browser is able to save file !!!
Ex : Whenever I try to save an image in Firefox/Chrome, it shows an error as below :
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
What I have tried so far :
- Root the phone and use Root Explorer to check the permission of "Download" Folder, it is --rw--rw--r-, tried to change the "other" to RW but failed.
- Wipe cache/davik code - not solve
- Factory reset/ Wipe data - not solve
- Clean everything and re-flash the stock rom still not succeed ((
Really appreciated If you have any idea on how to solve this problem.

su ->enter

adb emulator offline

so I was trying to install a custom rom for my nexus 6p like I used to do on my nexus 5 alot...
now i set up my adb and fastboot environment (throgh google's site) as I used to do and it all worked fine
then i tried to unlock the bootloader and it got stuck (only cmd not phone) in "adb devices" i got the device ID
and 2 lines of offlines emulators that i have no idea what they are... i dont run bluestacks btw.. i do run Virtualbox though it has windows 10 on it..

Fastboot is not working but adb is fine.

Hello everyone. I have my asus zenfone max pro m1 and I want to install a custom rom in it, which requires me to go to fastboot.
I have followed a post on xda forum about it.
I have unlocked my bootloader.
installed adb and fastboot (platform tools).
enabled usb debugging and allowed my pc.
Now when give the command for adb devices, it shows me the attached device. Then i give the command "adb reboot bootloader" and it works perfectly and I enter fastboot on my device.
But as soon I give command fastboot devices the fastboot menu in my phone changes to small font saying "press power button to shutdown" . But when I restart my PC and do it all again, the first time when I
give the command for fastboot devices it shows me my device , but second time onwards it shows "??????? fastboot" and again the same small font message is shown. I have attached screenshot of my CMD for better illustration. Please help me regarding this . Thank you.
