that's very rude people who post that crap deserve a timeout from posting. I hope they start enforcing the rules more around here because it's very sad to see the big name Devs start to drop off the map because of rude people like you! Devs do this for FREE in their spare time!!! they have lives too and most likely a REAL job! If you don't understand that this is a hobby and a challenge and they fix things over time... such as months and maybe even years the you should just go back to stock Samsung and be happy with what you paid for! said all I need to say!

[Samsung Galaxy S7 Edge Themes, Apps, and Mods] Killuminati91:
Big shout out and thanks to [MENTION=2516635]zeroprobe[/MENTION] who made this possible. Based this mod on his tweaks.

Features:

- Bitrate 1080p = 40mBit/s

- Bitrate 720p = 40mBit/s

- Bitrate Slow Motion = 60mBit/s

- Object Tracking + HDR + Effects for 1080p_60fps, QHD and UHD

- Phase Detection AF for 1080p_60fps

- Zoom in Slow Motion

- Removed unnecessary Pro-Lite Mode [No more doubled "pro" option in camera modes]

- Removed Stickers

- JPG Quality 98%

Installation:

- Clear Data and Cache of the Camera App

- Make a BACKUP

- Install the zip from TWRP

- Check if second pro-mode option is gone to verify the install

Installation [ODEX / Renovate]:

- Go to data/app/ and delete the "com.sec.android.app.camera-1" folder

- Reboot into TWRP - flash the zip

- Go to system/priv-app/SamsungCamera7 and install the .apk

Disclaimer:

This is tested on a Galaxy S7 Flat running KHONGLOI S8 Port. This does NOT work for S7 roms as the camera app is different. It MAY run on the S8 but since I dont have the money to upgrade I cant test it.

I had working 1080p Slow motion on the Galaxy S7 Camera but can not get it to work with the new version. Still working on that.

S8 Port ROMs only!
[Samsung Galaxy S7 Edge Themes, Apps, and Mods] koboltzz:
Very nice to see someone else who has modded the camera :good:

Let me make some suggestions:

- There is no reason to increase 1080p to 80mbit/s, because you won't see any more details than on 30mbit/s which seems the culprit (default is 17mbit/s)

- Slow motion modded to 240fps on 1080p sounds promising but you miss to tell us the bitrate

- JPG quality at 100% will only double the size of the pictures taken but do not eliminate any loss in detail <- this is only produced due to aggressive postprocessing (oversharpening). Set it to 98% instead and you will have smaller files with identical quality to 100% (default is 96%)

- Maybe you will find a switch in the apk to turn off postprocessing completely (for taking pictures), then we will be able to take jpeg in raw quality and just had to eliminate noise on high ISO

- Maybe you should try to get S8 camera apk running on our S7. This will be interesting due to new (real) HDR mode

Keep working on it, this has a lot of potential

[Xiaomi Mi 5 Questions & Answers] vichucoolics:
Mi5 is supposed to be underclocked at 1.8 ghz right but according to the droid info app it shows 1.3 ghz

Clock speed 1363mhz-1363mhz
[Xiaomi Mi 5 Questions & Answers] Deleted member 8058743:
Hi,

Snapdragon 820 SoC works with lutte.Big architecture.

In facts your mi5's SoC has 4 cores : 2little and 2big.

Little is well suited for light tasks as it is very power efficient and low power consuming.

On the other end, big is much power hungry but more powerful.

What xiaomi "forgot" to mention is that mi5's little core isn't clock at 1,8GHz (you guessed it : it's big's clock) but at 1,3GHz.

So don't wrorry everything is normal ^^'

Just check cores 3 and 4 They should be at 1,8GHz where cores 1 and 2 are sitting at 1,3GHz which is normal.
[Xiaomi Mi 5 Questions & Answers] spargel:
You should try CPU-Z

It shows all 4 cores and corresponding clock speeds.

2nd: your phone might be in power save mode. Switch to "balanced" to gain more clock speed.
[Samsung Galaxy S7 Questions and Answers] xmun:
I recently switched from a regular international Galaxy S7 (SM-G930F) to the Dual SIM model (SM-G930FD) and noticed an issue.

In my country (Malta - EU) we have three major mobile providers, one of these sends the caller number as 99###### whereas the others send it in full country code format +356 79######. I have all my contacts saved in international format for convenience sake during travel. Since getting the dual sim model, if my phone receives a call with the short 8-digit number, it's not matching the contact to the full country code. This did not happen with the regular international model.

Is there any way to correct this short of adding both formats to every contact?

Thanks
[Samsung Galaxy S7 Questions and Answers] pakidermo5000:
In my opinion it is not a problem of devices but software. Have you checked the ROM version of the dualsim handset?

Dualsims are not sold in Europe,so if you use stock version it is probable that it will not work.

Install the same ROM that you have on the single sim and try whether it works.

Just flashed Schaps 4.30 to my Vario II which we love by the way! It has a reg edit facilility on it but does anyone know how I can enable the GPS control panel to go with my external GPS gizmo? I'm sure I read it here somewhere but when I search for GPS it says there are no matches.

I'm sure its a quickie for some helpful peeps out there! Many thanks!

[8525, TyTN, MDA Vario II, JasJam ROM Development] djac965930:
There's no option or control panel for GPS in settings. Its not listed at all. I know that it's built into Windows but its hidden. I'm looking for the way to enable it to show up, which I think is done in the registry.
[8525, TyTN, MDA Vario II, JasJam ROM Development] JR_de:
The Wiki is your friend:

http://wiki.xda-developers.com/index.php?pagename=Universal_Registry

To hide or show the GPS connection in the connections panel

The settings are at 'HKEY_LOCAL_MACHINE\ControlPanel\GPS Settings'

The 'Hide' DWORD value should be set to '0' or deleted to show the panel and to '1' to hide the panel

The 'Group' DWORD value should be set to '2' to show the panel and deleted to hide the panel

For example, to show the GPS connection in the connectionss panel

HKEY_LOCAL_MACHINE\ControlPanel\GPS Settings\Hide = 0

HKEY_LOCAL_MACHINE\ControlPanel\GPS Settings\Group = 2

OR here:

http://wiki.xda-developers.com/index.php?pagename=WM5_Tweaks_Other

Add GPS settings icon

If you have a GPS device, you can add a GPS settings icon to your Start > Settings menu using:

HKLM\ControlPanel\GPS Settings\Group = 2 (DWORD decimal)

HKLM\ControlPanel\GPS Settings\redirect <-- delete, or rename, this value

Note that '2' stands for the Connections tab, '1' is System and '0' would be Personal

Note also that this has reportedly disabled one person's USB connectivity. To restore, set "GPS Program Port = None", "GPS Connection Port = None", "Automatic GPS Management = on"
[OnePlus 3T Questions & Answers] Archtects:
Hello, I've softbricked a fair amount of phones and tablets in my time but I must admit never had this show up. After flashing Twrp and a dm-verity thingy, I received this shiny new error on my new 1+3t. While I'm assuming it's a straightforward fix such as:

Booting into Twrp and flashing stock 4.x Oxygen os and the stock recovery to bring phone back to where I started.

My question is, can't I just go straight about flashing a rom? I.e freedom rom, or is it advisable to just try start again?

And is me flashing stock os then recovery got to work?

Everything is still stock there is no root. All I have done is:

fastboot > oemunlock > reboot > fastboot flash Twrp > Twrp boot > Twrp > swiped to Modify > flashed dm-verity.

I did receive a password request first time round but after I rebooted phone it wasn't there again.

Thank you for helping in advance.
[OnePlus 3T Questions & Answers] Funk Wizard:
You had to flash supersu or Magisk after the process to disable force encryption also make sure your are on the nougat supported twrp 3.0.4-1 or later

For anyone who get stuck!

3) with your pc get up Adb and:

fastboot flash recovery stock.img
Fastboot boot stock.img

4) Once you boot into recovery navigate to install from adb.
5) in cmd again on pc type
[CODE] adb sideload filename.zip

6) then reboot :). You can leave it here if you want.

I don't know much about Android development, so I want to ask if this is possible at all.

Newer Android versions allow user to select Webview implementation used in every app that uses Webview. Currently you can (mostly) choose between Webview, Chrome stable and beta (depending on what's installed on the phone).

What is the roadblock for making open-source Webview implementation, that would also block ads?
