Change Phone Type Recognition - General Questions and Answers

In the same way that websites recognize mobile devices vs desktop computers - and alter their visual and use formats to each one; some android applications recognize cellular phones vs wifi tablets, etc. and also alter the way the applications behave.
Example: google voice on a tablet can dial out calls with just the google voice number. google voice on a cellular phone that has no cellular service cannot dial out with just the google voice number over wifi.
(This is a somewhat un-recent change in application programming, and so far does not affect incoming calls.)
Q: Can an android cellular device be programmed, rooted, or OS swapped to appear as non-cellular device?

When Android device boots up then always the ratio between pre-defined screen height and screen width get computed and the device's screen orientation is accordingly set: either to landscape mode (value of height <= width ) or to portrait mode ( value of height >= width ).
By means of ADB - or several 3rd-party-apps - you can set screen's default width and height to be used.

How does altering the screen dimensions make an application such as google voice believe it is running on a tablet instead of a cellular phone?

Why are some data entry fields too small?

Hey all,
I've searched around for a solution to this but it's a difficult problem to search for!
On some software that I've installed on my htc touch pro the data entry fields (for example a box to enter the data in pocket informant) are too small so the whole date doesn't get displayed. Is there a way of fixing this? I have gone into screen in the system options field and set the font size to smallest but it hasn't made a difference.
Anyone else experience this? Really annoying as very small entry fields you can't see the text at all (for example entering a height in mysporttraining software).
Chris
--EDIT--
Ok I figured out what the problem was. Couple of days ago I used advanced config to edit the size of vertical scroll bars to make them nice and wide. Reason being to help one finger scrolling as the default is too small. Anyway it appears to also change the width of number incremental arrows in text boxes! So they had become huge covering up the text....doh! Reset the size back to default and the textboxes now appear correctly.

General Ready For desktop mode screen orientation (G100)

I have a monitor that i can rotate vertically (Dell UltraSharp 23 Monitor - U2312HM), but it does not have a built in screen orientation setting. Most operating systems have that though, but as far as i can tell, the desktop mode for this phone doesn't have that (desktop settings are very limited). It's weird how android has that option by default, but it's not added in the desktop mode. It seems that Motorola did not consider that some monitors can be rotated (or even the compact tablet like screens); vertical desktop has its uses and many apps are not optimized for being stretched out horizontally. It would also be nice if i could do the same in screen mirror mode - change the screen orientation only on the monitor, so the phone's vertical orientation could use more of the monitor's screen.
I would like to know if there is a workaround for this.

Question [GUIDE] Device Settings Menu | Part III - Display, Lock screen, Biometrics, Security, Safety

Device Settings Menu Guide, Tips & Discussions
Part 3 - Display, Lock screen, Biometrics and security, Safety
If you're new to this series or want to see the index, please read the Introductory Post first.​
Display
Dark mode settings: I have kept it 'Turn on as scheduled' with 'sunset to sunshine'. If scheduled, the dark mode is only enabled after the screen gets off.
Brightness: When you change brightness in 'Adaptive brightness' mode, your device is smart enough to learn your usage patterns to determine the best level according to the environment as per your preferences. 'Reset usage patterns' in case you think your phone is drunk when in Auto mode.
Motion Smoothness: You have a monster with a 120 Hz refresh rate! Use it with 'Adaptive' mode. It also saves battery keeping your refresh rates low when not needed. 'Standard' mode uses a constant 60 Hz refresh rate. Use it when you know you will be scrolling and watching movies but want to save battery.
Eye comfort shield [Formerly Blue light filter]: Learn why you should use it here. I've set it to 'Custom' > 'Turn on as scheduled' > 'Sunset to sunrise'. You can toggle it from the notification panel as well. Still need to see how the new 'Adaptive' mode works - it claims that it makes minor adjustments throughout the day. Anyone can comment?
Night Mode: (Pie update) Enable it to make use of true blacks on your AMOLED screen, save battery and put less strain on eyes. I know you want it to only enable at night, so hop up to developer mode and set 'Night mode' to Automatic.
Screen mode: I've set it to 'Vivid' to let Samsung be where it is best at - Display Vibrance! If you are towards the cooler or warmer side, you have now the option to customize with 'White balance'. In 'Advanced settings', you also get to tweak RGB colours!
Font size and style; Screen zoom: I've set 'Screen Zoom' to 'Small' and 'Font Size' to Level 2 in order to get more content in a screen view. Please tell me if there's any better font on Galaxy Apps.
Screen resolution: By default, you don't get the resolution enabled that your S22U is capable of. I've changed it to WQHD+ for getting the most out of the best display in the market. I've the resolution set to HD+ in Medium Battery Saver mode in case I'm on Survival mode.
Full screen apps: I customize it when needed for an app. You can tell which apps should not show your camera cutout (so they show a bar instead)!
Screen timeout: Mine is set to 10 minutes. You know, pro users!
Home screen: Self-explanatory and I use Nova Launcher. Do enable 'Quick-open' notification panel.
Edge panels: You can set a maximum of 9 panels. Explore options for each panel and try more of them from the Store. I've enabled Apps edge (also make app pair and folders), People edge (upto 10), Smart select (take portion screenshots, make screen GIFs, pin a screen's content), Clipboard edge (auto-categorizes items), Reminder, Device maintenance (useful to review device performance OTG), Tasks edge (explore all available tasks), Quick tools (must have), Calendar. Tap Menu and 'Reorder' the panels as per your needs. In 'Edge panel handle', I've set the Transparency to highest and Size and widht to larges. I've dragged the handle to Right near power button so that I can always guess where the handle is.
Navigation bar: You can enjoy the immersive display by setting 'Navigation type' to 'Swipe gestures' and disabling 'Gesture hints' and 'Show button to hide keyboard'. I eventually got used to this. You also have an option to go back by dragging the sides. You can use Nav bar button on Quick Settings by dragging down the notification panel to toggle showing the navbar then.
Accidental touch protection: Really useful because I keep my phone screen faced to my leg side when inside pocket so that it's protected from the outside cruel world.
Screensaver: In case phone is your life even when it wants to get charged peacefully.
Lock screen
Screen lock type: I use Pattern with Biometrics (Intelligent Scan and Fingerprints mostly Fingerprints only). Fingerprints remain the best security and battery-efficient method to date at least for me. Use Iris for more security than regular face recognition. Also, with Iris, your device won't get unlocked while you're sleeping or with your photo. Use 'Intelligent Scan' for bit more ease (read about it here).
Smart Lock: It's a Google feature that can unlock your phone via On-body detection, Trusted places/devices and Voice Match. I used it once with On-body detection but couldn't impress me. Read about it here.
Secure lock settings: Disabled 'Make pattern visible'. Set 'Lock automatically' to 15 seconds in case I want to turn on the screen immediately without unlocking it. Anyways, 'Lock instantly with power key ' is enabled when I explicitly want it to get locked. Use 'Auto factory reset' carefully as someone could initiate this by simply making incorrect attempts. I've enabled 'Lock network and security' especially for theft use-case.
Always On Display: For customizing it, go to 'Clock style' below. Guide on AOD here and video here. You now have new display mode as 'Tap to show' AOD for 30 seconds. I've set it to 'show as scheduled' such it doesn't glow when I sleep. Also, I get an idea that it's time to get to bed when AOD stops showing up (same for wakeup).
Clock style: You can customize AOD with different clock styles, pictures, GIFs, Calendar and roaming clocks. Blue 'colour' gives a soothing effect every time I look at the clock for me. Similarly, you can customize your Lock Screen clock style here.
Content to show: 'Home button and clock' feel elegant for me.
Auto brightness: If enabled, you can also change it by double tapping the AOD clock. I have set it to the maximum to get eyes on it!
Show always; Set schedule: If you often check the clock at night, you can enable the former. I've disabled AOD during my night sleep schedule so that I additionally get a hint when it's already time to go to bed and whether it's time to get up or not.
Turn off to save battery: Enabled. Do you need AOD in survival mode too?
Roaming clock: I had to disable it as every operator in India puts SIM to Roaming mode when you're out of your circle (mostly defined to a state) and I get two identical clocks whenever I travel out of state.
Widgets: Enabled all available choices and will decide about the reordering or need of each of them after I arrive at the use-cases. The same goes for you maybe.
Contact information: Do fill it. I've included my name and number on it. Can be useful when stolen, lost or misplaced. You can include email or alternative mobile numbers as well since the primary number would probably be in the device itself.
Notifications: I've changed it to 'Details' from 'Icon only' since later makes it similar to AOD style notifications and I want the description of notifications once I go over my AOD screen. 'Hide content' if you don't want people to read your notifications. I rather do this on a per-app basis (like messages for OTPs, sensitive apps). 'Notifications icons only' Toggle 'Transparency' if you find it difficult to read notification over the wallpaper or want your wallpaper to expose. 'Auto-reverse text colour' makes it easier to adapt with the wallpaper. You can define 'Where to show' your notifications here (AOD or Lock screen or both).
Shortcuts: Define the two shortcuts you see on the bottom screen corners while on lock screen. You can choose any app though default (phone and camera) works for me.
Biometrics and security
Biometrics: You can remove biometrics data and configure 'Samsung Pass' to use these here. You can enable 'Screen-on' scan for making the device scan for your face as soon as screen turns on. This increases brightness immediately while it's scanning (can be annoying) and will drain some battery. In 'Fingerprint Scanner', you can add as many as 4 fingerprints (reserve one for Secure Folder).
Screen transition effect: Disabled as I want things at fastest.
Google Play Protect: Enabled. Read more here.
Find My Mobile: 'Remote controls', 'Google location service' and 'Send last location' enabled. This should be the first things to review once you buy the device. Prepare yourself with a demo on findmymobile.samsung.com.
Security update: Shows the patch level and gets updated with 'Software Update'.
Samsung Pass: Saves your passwords, addresses and payment information securely.
Install Unknown Apps: Allow/Disallow existing apps to install apps from APK.
Secure Folder: The replacement for Samsung My Knox. Must-use feature to separate your very private and confidential part of the phone. Guide here and video here.
Private Share: You can share your photos and videos without letting anyone save or download it. Uses blockchain. Need to learn more about this.
Other security settings: 'Set up SIM card lock' disabled (same reason as in 'Secure startup'), 'Make passwords visible' disabled, 'Security policy updates' auto update enabled (Here is what are these), 'Send security reports' enabled. Set 'Device admin apps' with care (Learn about them here in case you haven't). You need to remove an app from here before uninstalling it. 'Creditial Storage' for CAs and user certificates (Learn more about CAs here). 'Pin windows' is a very useful feature for me. In cases where you need to give your device to someone (for like watching a movie or seeing the gallery), if this is enabled with 'ask for pattern before unpinning', when you 'pin' that app (video player or gallery), people will have to pass the lock method to get out of that app. Configure which apps can have 'Usage data access', 'Notification access' and 'Do not disturb permission'.
Privacy
All permissions; Permissions manager: Manage and view granular level permissions per app or apps per permission basis.
Controls and alerts: You can set if apps can have 'Camera access' or 'Microphone access'. Disabling this makes no installed app to access these - could be done when you are in spy mode. You can also get alerted when an app accesses your clipboard with 'alert when clipboard accessed'.
Samsung: You get the privacy policy in Samsung Privacy. In Customization Service, I have disabled Use mobile data to save my data against nothing important. You can also request to Download your data Samsung has collected about you.
Google: Just like above, see what Google collects!
Location
App permissions: Allow apps and sites to detect your device's location. I've enabled it since I use too much location-specific content. You can turn it off if you suspect your dad working in NSA (approx. locality can still be tracked through IP, use VPN). If you need to enable Location for an app, I suggest using Allow while using app than Allow all the time for apps that you think only needs to use while you are using the app. Why allow Instagram to get location all the time when you only need it while sharing something? Google Maps, on the other hand, can give you information about upcoming traffic if allowed in the background!
Wi-Fi scanning; Bluetooth scanning: Wi-Fi scanning uses the database of Wi-Fi locations to predict your location. Read how it works here. Similar goes for BT.
Safety and emergency
Fill your Medical Info like Blood group and conditions so that any help knows about this when life goes wrong.
Add your Emergency contacts so you can access them on lock screen.
You can enable DND while you are driving with Silence notifications while driving.
Emergency mode [Formerly Ultra power saving mode]: You get a black screen that enables you to call and text. Saves a great battery when you are in survival mode. You can add few apps like WhatsApp too!
Panic mode: Keep this enabled (can save you) and when you press your power key 3 times, your device sends Location, Emergency text and photos from your camera to your selected content. Be careful that you are likely to press the power button multiple times when you are stressed and you would be sending unwanted photos to your contacts. Either disable the photo-sharing option or select contacts carefully.
FAQs
Does having Adaptive Refresh Rate really work better with a battery instead of 60 Hz? (Asked by @brokyneo)
Ans: It depends on the usage. If you reading something and not watching dynamic content like videos, you don't need to refresh the screen 120 times a second!
Adaptive Refresh Rates on S22 Ultra has 7 rates: 10Hz, 24Hz, 30Hz, 48Hz, 60Hz, 96Hz and 120Hz. With 10 Hz, you essentially make the GPU display frames 92% fewer times! This should save your battery to a great extent!

Question Device restarts in Tablet mode

For some reason whenever I reboot my device it loads in tablet mode which is really annoying. My widgets all get removed and the display size is very small, along with other home screen changes. Once I change the display size setting the phone recognizes it is not a tablet and goes into phone mode. Does anyone know why this could happen? Phone is rooted with safetynet fix. Wondering if it might be safety net fix since it changes the build.prop settings. However I would have expected others to experience the same issue.
go into dev options and look for a value called smallest width. This stock is set to 411 dp. If yours shows that value, set the display size to the smallest possible, then go back into dev ops and change smallest width to 411 dp again, then go back to screen and font size and set those to largest. mess round with those till ya find what you want.
Cheers Mate!

Thanks for the reply. Mine is set to 485 because I set the display settings to smallest. When I change to 411 it just changes the display setting to default option. When I change back to smallest display option it changes the smallest width back to 485. Not sure how this changes the tablet mode setting when I restart phone.
