picture-in-picture checkup 2020

let’s have a look how to use, why it is useful, what other alternatives are around or how to implement – this was introduced recently in iOS14, appletv already provide this feature, but just in tv app

almost every modern tv got it’s own picture-in-Picture (PiP) and even youtube in browser offers a PiP option with a miniplayer

beginning from api Level 26 the PiP is available for android devices, very useful to navigate with google maps while browse for a new playlist … but:

  • feature support no equal between vendor and app developer (e.g. brave browser doesn’t switch to PiP from fullscreen on honor devices)
  • picturesize is not scaleable, there are just 2 predefined views
  • usability how to open differ from os level or vendor

in my opinion, the best way to view video while doing something beside is splitscreen view with 2 different apps/browsers, although is depends on vendor/app > long press recent apps button on huawei respectively swipe up at samsung with long press relevant app icon to show option, or use app pair from samsungs side panel

with apple’s new mobile os 2020 this feature is finally also available, even your able to make video window larger or pinch to zoom and you got the option to keep audio playing while docking video side and with the benefit of the same behaviour for all iOS devices

save data or at least reduce the consumption, optimize for rural regions, holidays, etc.

your inclusive data volume is up… throttling to 64 kbit/s.

the consuption of data doubles every year, the mobile abo’s evolved as well but there is a gap between the required data volume for services and the availbale mobile capacity, below approximately amount for different services

teams e.g. need for a group websession 1 Mbps, when turn off incoming video it could reduced further for about 75%, tested by myself, round about 1GB per workday

read below some further tipps in different catagories to optimze mobile data consuption


windows

right at your windows10 device, your can select your phone hotspot as a metered connection, cellular data connections are set as metered by default

below you can additionally view data usage per app and set a data limit

chrome android

  • at your android enable for chrome browser the lite mode in settings > advanced > turn on lite mode
  • data usage of apps and set a capacity limit could be reviewed in settings > mobile network > data warning (depending on android vendor)
  • file download, disable in your mail client or chat app the automatic download of media and attachments
  • other browser e.g. Brave to use integrated add blocker and enable data compression
  • battery saver, when enabled disallow app launch in background and disable push notifications

iOS

with iOS13 there is a new feature called low data mode, enabel in settings > mobile data

also possible to review the volume per app in mobile data and disable unreqired

spotify

reduce consuption for your favourite playlist, choose

  1. tab start
  2. tab settings
  3. tab data saver
  4. enable it

offline

try plan to use offline apps, while download and store data infront of traveling, read below

gather ios device logs on the fly without a mac

it usually requires a mac with configurator installed to gather iOS device logs while troubleshooting an issue, there a some alternatives around…

#1 virtualize macOS

… and use apple’s configurator on windows, read more how to establish this below

touch @macos

apple introduced the “all news” touch bar in 2017 for macbook pro, but what most mac users missing is a touchscreen – the addon airbar, extra hardware attached to the screen, looks unbeautiful every smartpsmartsmaand a lot other notebook own a touchdisplayt, so what to do if you don’t want to run or carry separate device – vitualize… Continue reading touch @macos

#2 itools

as an alternative software for iTunes, it it further able to access device logs and is supported at windows & macOS for the following devices

switch android phone and (easily) reconnect your wear smartwatch

largely relegated to checking notifications, counting steps, and maybe measuring your heart rate from time to time

in Q3 2019 the wearable band shipments grew 65% and propably below some christmas trees

beginning 2020, one-in-five americans use a smart watch or fitness tracker, according to a Pew Research


apple released in 2019 it’s watch series 5 with built-in compass and Emergency SOS application on cellular models

google smartwatches, running wear os, without an update since rename in 2018 – need oem vender to push the mobile os – xiaomi succeed with low prices to the global leader with 27% share – huawei reached annual growth largest wearable growth of 243% – fitbit recently sold to google


what’s embarrassing with wear os is the switch to a new android device, there is no guide to reconnect, you had to erase the watch and reconfigure – some apps on your mobile device offer the option to install as extention onto the watch, but all other needs to be installed manually one by one

but the is a clever guide to use the developer option to reconnect to a new device, without the need of resetting

simply enable usb debugging, disable blueooth, connect your wearable to android studio/adb tos, execute to following

  • adb devices
  • adb shell “pm clear com.google.android.gms && reboot”
  • adb shell “am start -a android,bluetooth.adapter.action.REQUEST_DISCOVERABLE”

iOS security framework like a swiss cheese

apple did a quite good job with the restrction of openin function between managed and unmanaged apps, and advanced it’s separation within it’s native mail and even contacts app

  • allow open documents from unmanaged apps to managed apps
  • allowUnmanagedToRead ManagedContacts

read more >>

manged_contacts

but

there are still leaks in the security framework to get around enterprise restrictions, further details below


openin

apps and even accounts are separated in managed/unmanaged, via enterprise deployed exchange configuration could blocked to move/forward messages to other email accounts within the native apple mail app – the separation between private/business accounts highlighted in colors red/blue through managed domain configuration and also apply to safari domains, downloaded files from managed web domains could only be shared with managed mail accounts, 3rd party apps could implement app configuration to disable copy/paste, sounds perfekt so far,
…but it is still possible to copy/paste business data to private

quick look

an opened document in nativ viewer also respect to managed/unmanaged restriction…
…but when open the file in quick look, you able to send the file in any account without restriction

pictures

it is possible to save media to gallery, for sure it is possible to perform a screenshot but is a bit more tricky

lockscreen

via enterprise registered bringyourowndevices could display sensitive information without the need to enter device credentials at the lockscreen, a mangement system could block the information for devices registered

  • allowLockScreenNotificationsView
  • allowLockScreenTodayView

… but this would impact also the notification for private apps

keyboard

furhtermore for byod it is hard to maintain security without restricting private use, users could use custom keyboard with potential embedded keylogger, iOS developer could add a code below in their project’s to present default iOS keyboard


stay tuned for iOS13 adding more security features 🔐 and privacy with user enrollment 🔏
