[Q] using android as wall display? - General Questions and Answers

I want to mount my old galaxy tab on the wall, keep it plugged in and awake, and use it as an information display from wifi. I specifically want to show the outdoor temp, expected high temp, and time. In other words a wall display I can control from my always-on PC.
I am a programmer so I can write PC software but I would prefer to not write android software. I'm hoping some existing app could show text or probably an image and remotely change the text or image.
I doubt such a thing already exists but I'm hoping someone can help me come up with a clever (kludge) solution.

Increase Smart Phone Battery Life

Hi, firstly I'm sorry my english is a little bad )
Did you even harder to charge your smartphone is based on the first day? Here are tips that you fully based. Get away from the stress of the outside end charging of battery life and increase your phone.
1 - Home Screen Wallpaper and Theme you are using:
If you are using a smart phone with AMOLED screen, predominantly black wallpaper should be preferred. AMOLED technology while light colors such as white because it consume more power. LCD and SLCD screens, such a situation is not in question.
My suggestion is not to use an animated wallpaper for Android users in particular. Animated wallpaper, using the phone's hardware more. This is going to have to consume more power than the components.
Android users should note also displays add to the widgets. Widgets are always synchronized with the running and intense 3D graphics, as well as the equipment used for the data connection şarjınızı effects shot.
2 - Display Lighting:
It is best to leave the automatic setting of this area.
But I do not like to remain on automatic. If you need to talk I'm being honest, I always light at the highest level. Because all the ingredients here, and it will not have to perform the charging period will be longer.
But I do not want to go up to the maximum number of days gidebilecekse say it, my proposal is worthwhile to listen to. Big and wide screens of smartphones, especially in the light of day very well read. Do not force the phone to the light a little bit, then move to a higher level.
But it starts to get dark, shine your light, especially in the evening turn down the screen. Smart phones display lights to a minimum, even offers sufficient light in the evening. This is an effective tactic.
3 - Wireless Connections:
Smart phones are undoubtedly the most power-consuming units, wireless connections. WiFi, Bluetooth, GPS and 3G that are overviewed, 3G and GPS fully charge the enemy.
According to their attempts, with the closure of all wireless connections between all of them to be open to play at least half a day I've noticed.
For example, turn off the GPS. Only helpful both when business is active. Shortcuts available in Android and Symbian Belle. The option to turn on and off in a practical way. We also do not walk Bluetooth is on. It is also charged unnecessarily waste.
A clear grasp of 3G and WiFi when it is, let's not say conect. When connecting to open it. If you say'm going to necessarily turn off syncing on Android.
Sync / Sync, for a certain period of time it şarjınıza negative effect on the data are drawn. When you use the most sense to synchronize.
4 - Your RAM (temporary memory) Operate the program free to leave and at the bottom:
Most are at fault here. If you open up the application on the phone and waiting at the bottom. E, the processor is running at full speed all the time. The conclusion is obvious.
And then they were going at the charge of the phone as well as the complaints are coming slowly. Take a notebook and a lot of that time in the program's run, so let's wait. Let's see what is going to charge?
There are applications for the program terminates, especially Android. But most of these applications 24/7 has an adverse effect charging them for trying.
I would recommend this program to Android users. Download this app. Click on the widget closes all running applications. However, if you open the program by clicking the icon, you can see and what you want Implementations running off. I would recommend this method.
When you close all the system applications to open them again, the power turns off, and then spends the processor. Here you can download the program[/URL]
5 - Efficiently Manage Your Smart Phone Processor:
This section applies to users Root'lu. Root evaded users have this right, they do not die. Linux-based smartphones, especially those driven into exile in the market with a certain processor speed settings.
In general, the phones are set to OnDemand, the processor can adjust the speed according to the amount of use. For example, a 1 GHz processor that the phone does not work all the time at 1 GHz.
Their phone for the sake of example, a 1 GHz - 265 MHz range is running. I changed speeds. If you charge the phone and the maximum to withstand reduced from 500 to 128 can do. But later in your job will be completed on the processor to use 100% of himself. This will mean that the screen backlight to stay on and wait for you. I mean, at least let it charge the struggle, suffering Pull spend more charge.
I phone 1190 - 450 range using the. I can do my work as well as installing and getting faster. Charging time is important, 1190 - 128 range I choose.
Forget! Reduce the processor speed on the phone, when trading amplify şarjınızı. Because it is trying to slow the processor 100% to use and work will be completed on your screen light will stay open late.
6 - When charging the phone's battery Full Fill:
Do not say we already have would remove 100% charge to fill it. Phone software does not fully charge the battery. Leaves a certain margin of tolerance. Here we also benefit by it. In particular I saw that HTC Desire'da tried and successful. Each company's share of each model, it will not stop. But you can be on your left. Does not hurt to try.
Explaining the steps for:
-Phone up to 100% of full charge.
-Turn off the phone, remove and charge the phone.
-Install and charge the phone again, wait until bekleyebildiğiniz. (1-3 hours)
-Turn your phone into the phone, and remove the charge.
-Wait for your phone to do nothing between 2-5 minutes after opening. (Not attached to Sharjah)
-Turn off your phone again and again for at least half an hour into charging.
Remove and use the phone in the normal-charging. The procedure is finished.
This method has been calibrated with the battery is charging and fully. Enough to do this once. And then he goes to full charge.
7 - Special Edition Operating Systems Aim for:
Android users who root for in this Article. Made by the manufacturers of Android devices, phone skins, chargers doing negative effect on life.
TouchWiz, Sense interfaces, such as, the system is more tiring, as they lower the charge time. So we have the benefit of using a pure version of Android.
With pure Android versions like CyanogenMod custom Android versions sure to use similar interfaces. The term of charge with a very stretched. Will be surprised.
Of course, I do not recommend this method to anyone. Aware of the change and the risk of all the phone's Android software will recommend it to our readers.
Suggestions useful to you?
Thanks!!! i will follow these tips :good:

[APP] Use phone's camera to color calibrate your monitors/tablets

If you need to calibrate your monitors/tablets but can't justify spending hundreds on a colorimeter, then check out this app
Camera Colorimeter
A camera is a color capturing device so can be used to take color measurements of your monitor. Data is sent wirelessly over Bluetooth to a companion app running on your laptop/PC/tablet (whose display is to be calibrated)
Display Calibration
Works great with the camera on the S7/S6, and other devices too (e.g. Nexus 6).
Enjoy!
Hmm.. unable to use for my desktop pc LCD's... (Windows 10)
No bluetooth, but wifi connection
Sorry Wifi is not currently supported.
You could try hooking your monitor to a laptop and run the calibration there, then copy the generated ICC profile to the desktop PC. AFAIK calibration profiles are specific to each display and not dependent on the graphics card or PC.
i just discovered this wonderful app but it seems to work for windows 10 only and im not on win10 for obvious reasons. any chance to get this app working on win7 or 8?
also can it calibrate a triple screen setup?
In order to have a separate color calibration profile for each display in a dual/triple monitor setup your graphics card must support multiple gamma LUTs,. You would then need to calibrate each monitor and install the ICC profile generated by the app separately for each monitor.
At the moment the app only runs on Windows 10, but if there's demand I would consider porting it to Windows 8.
Just use it to calibrate my surface pro, one dell monitor and one generic monitor (China brand monitor). All are IPS type. It Work good on surface pro (i have a calibrated profile), but bringing everything too warm on Dell and Generic monitor. Is there any precaution / setting to take note?
Hmmn.. I have a Samsung TV that Best Buy was trying to get me to have them calibrate the colors for $300 when I purchased it. Does anyone know if I can tune the colors of my TV this way?

Sorry, these apps only work if you're planning to use your TV as a PC monitor. They aren't meant for calibrating for general TV viewing.

Hi vyis, the general precautions are that prior to running the calibration, make sure that the monitors are set to the "Normal", "Standard", "6500K", "sRGB" color settings. This is typically achieved by resetting the color settings on the monitor to their default values.
Secondly make sure that there is no other color management software running. Some graphics cards install their own color management software which need to be disabled/uninstalled.
And thirdly make sure that there is no active calibration (ICC) profile. The apps can detect this upon startup but it could get confused if you have a multi-monitor setup. To be sure, please disable Windows's color management by inputing "Color management" to Cortana and select "Change advanced color management settings for displays, ....". A "color management" dialog will appear. On the "Devices" tab, uncheck the "Use my settings for this device" checkbox. On a multi-monitor setup please do this prior to running the calibration process for each monitor.
Hope this helps.

I have done these all and redo calibration, still the same issue. I start to wonder this due to matted display. I have tried it on another laptop with glossy display and it work fine.

I have tested the app on matt displays and they worked fine. When you said the calibrated results were warm, were they very far off or only slightly off? Have you tried hooking the monitors to your surface pro or laptop where the app worked (on their builtin screen). I'm just trying to eliminate other variables.
Link for Windows app not working.
Windows application does not exist
This application worked well for me. It's a shame that it's getting such terrible reviews on android.
I had no issues getting connected and running the calibration. Just follow the instructions and you'll be fine.
Thanks for the suggestion OP!
The Windows app is only from the store? No Win32 version?
I'm running 10 but Enterprise LTSB 2016 which has no store or apps
Doesn't work with macOS...no wifi mode.
https://www.microsoft.com/en-us/store/p/display-calibration/9nblggh4wd9s#
This is the link I found for the app in Windows Store.
Is there a free version?

Could you make a version allowing one Android phone to calibrate the screen of another?

Thanks for your interest but unfortunately Android does not currently allow one to install a custom color calibration profile.
Hopefully this will change in a future Android release.
no paired devices present
I have the software installed on windows 10. and i have the app on my android phone (LGV30). however, the program does not see that i am connected with the bluetooth dongle. my bluetooth device is an older IOGear unit. but it recognizes and pairs right up. windows sees the phone, but not the display calibration application. any ideas?

Simple app for orthodox Jews

Hello everybody.
So, I have just purchased a Gear s2. I know it's late, but it finally got cheap enough for me.
There is something I believe to be very simple to develop and very useful for millions of orthodox Jews: We have issues with electricity on Saturdays. Simply put, an app that turns the smartwatch into a dumb watch for either a given period of time, or until one of the buttons is pushed, would do the trick. This means that the time and date would be constantly displayed in the most energy saving manner possible, touch screen and all other sensors on the watch are off, and all connectivity is off as well.
A simple version of the app will allow the user to turn it on and off manually. A more sophisticated version will know by itself when to switch to "dumb watch mode": the times when a user needs his watch to turn dumb are calculated by ancient Jewish calendar and clock. But they are preset and known in advance. There are many apps, programs, calendars add-ons, etc. that already know to calculate those times. Applying such existing plug into the smartwatch would predetermine when it needs to get dumb and when to get smart again, without the users' need to do anything manually.
Can this be programmed?
I think enabling both Airplane Mode and Power Saving Mode may be what you're looking for.

Turn really old phone into radio/spotify clock?

Hi,
I asked this on i9000 subforum, but I guess noone is looking there anymore - the question applies to any old phone, so I'm posting here as well.
I've got an old i9000 lying around, and want to make use of it. I want a replacement for an old radio clock in my bathroom, with following features:
1. display time (duh!) in large letter
2. ability to only turn screen on when there is ambient light would be great! (to save OLED display)
3. connect to wired speaker
4. use FM radio
5. act as Spotify client (preferably for multiple accounts)
Can I get some advice what software to use? (especially (2), I can't find anything...)

Question Phone Notification when Watch is Low Battery? 20-25%

Is there a way for my PHONE to notify me when my watch battery is under 20%-25%, set maualy the procent.
Not every time wear my watch, any somtime is discharging to 0, an app to notiffy me on my phone is very good.
Haven't seen anything, but would be good feature to have...
I hope a developer sees the requirement
I am willing to pay for the application
It’s not an App, but the functionality you mentioned is possibly with a combination of Watchmaker Watch-Face + Lua-Script and a Tasker-Task. But this is only a workaround or very special use case
It is a good idea. I am not sure why the WEAR app doesn't support it. I suppose they assume you will notice the watch, itself, notifying you. But it only does that when it is REALLY low and asks to switch to low power mode. Plus, doesn't help if you have your watch off your body at the time.
