Apple Officially Releases iOS 15.2.1 Update

Technology-Portfolio.Net - Apple has released software updates for iOS 15.2.1 and iPadOS 15.2.1, for iPhone and iPad devices.

Through this update, Apple brings a number of fixes to address the loopholes and bugs found in iOS 15.2. One of them is a bug fix where photos from iCloud Link fail to load when sent via message.

iCloud Link itself is a service that allows users to share photos and videos via iPhone, iPad, iPod touch, and the iCloud.com site.

This service is temporary, so all photos shared via iCloud Link will be automatically deleted after 30 days.

After successfully saved in iCloud Link, users can copy the link ( link ) of the photo or video to be shared via messages in Messages or Mail services. However, due to a bug , iOS users who receive photos via a link in the Messages service are often unable to load the photo in question.

This is of course very annoying because users can't see photos included in short messages sent by other people.

This iOS 15.2.1 also addresses a bug found in the HomeKit protocol. The bug is a loophole that can make an iPhone or iPad not work.

Through the loophole, a malicious individual could change the name of a HomeKit-compatible device to more than 500,000 characters. This can cause the device to malfunction.

Other fixes focus on third-party CarPlay app services that sometimes struggle to respond to user input.

The presence of this bug seems quite annoying, considering the high reports from iPhone users who complain of similar problems.

Usually, iOS updates can be obtained automatically. This is indicated by the appearance of a special notification on the device But if you don't get it, users can update the system manually.

To do this, users can access the Settings menu > General > Software update.

The iOS 15.2.1 update is about 970 MB in size.

Devices from Apple that are already compatible in the iOS 15.2.1 list are revealed in the sector on the iPhone 13 starting from iPhone 13 Pro Max, iPhone 13 Pro, iPhone 13 mini, iPhone 13 iPhone 12, iPhone 12 Pro, iPhone 12 Pro Max, iPhone 12 mini, iPhone 11 Pro Max, iPhone 11 Pro, iPhone XS Max, iPhone XS, iPhone 11, iPhone XR, iPhone X, iPhone 8, iPhone 7, iPhone 8 Plus, iPhone 7 Plus, iPhone SE (Gen 2), iPhone SE (1st Gen), iPhone 6s, iPhone 6s Plus, iPod touch (Gen 7).

While tablet devices will be available on the 12.9-inch iPad Pro (Gen 5, Gen 4, Gen 3, Gen 2, Gen 1), iPad Pro 11 inch (Gen 3, Gen 2, Gen 1), iPad Pro 10.5 inch, iPad Pro 9.7 inch, iPad (Gen 5, Gen 6, Gen 7, Gen 8, Gen 9), iPad Air (Gen 2, Gen 3, Gen 4), iPad mini (Gen 4, Gen 5, Gen 6).

Instagram Tries Edit Grid Feature to Create A More Aesthetic Feed

Technology-Portfolio.Net - Instagram is testing a new feature called Edit Grid. This feature will be very useful for Instagram users who want to have an aesthetic profile feed.

Currently this feature is still in the development stage. But developer and leaker Alessandro Paluzzi managed to dig into it to show how this feature looks and works before it is rolled out.

In a tweet on his Twitter account, Paluzzzi shared two screenshots showing this feature. The first screenshot shows the edit profile page showing a new option called Edit Grid.

If the user selects this option, they can change the order of the photos on the profile page. Instead of bothering to delete or archive photos, users can simply drag-and-drop the photos they want to move to make their profiles look neater and more aesthetic, as quoted from XDA Developers, Thursday (13/1/2022).

Currently, Instagram has not shared information about this new feature. But chances are they will reveal more information once this feature is ready to roll out.

As it is still in development stage, this feature will be rolled out to beta testers first before it is released to all users. It is also possible that this feature will be canceled for one reason or another.

In addition to the edit grid feature, Instagram is also testing three ways to sort content in the main feed, namely by upload time chronology, based on a proposed algorithm, and based on the order of favorite accounts. These three new feed views will roll out in the second half of 2022.

This phone will be equipped with MIUI 13 operating system.

Meanwhile, as the main kitchen, the Redmi Note 11S is thought to be powered by a Mediatek processor. Rumors about this processor are still very vague, some say Helio G95, but others suspect Dimensity 810 - the same as on the Redmi Note 11 which will launch in October 2021 in China.

Speculations are circulating claiming that the Redmi Note 11S could have an AMOLED display with a refresh rate of 90 Hz. These are still just leaks and predictions so we need to wait for the teaser regarding the Redmi Note 11s.

Getting To Know More About and Benefits Of VoIP Business Phone System

Technology-Portfolio.Net - VoIP technology is one of the results of the development of the latest technology today. This technology will make it easier for you to communicate. To help you take advantage of this technology, you can read detailed reviews and benefits of VoIP technology for the communication process.

Knowing IP Phone or VoIP Technology
VoIP technology is the latest modern communication technology. VoIP is Voice Over Internet Protocol which is often referred to as IP telephone or digital phone. This technology is voice that will be sent and converted into data first and then sent to the recipient via the internet network. This VoIP technology will change the voice with the help of internet protocol. VoIP has been implemented in various types of open source standards and procedures with various benefits for communicating.

VoIP This is different from standard telephones that use the traditional public telephone network (PSTN).

This digital IP-based telephone service uses control protocols such as Session Initiation Protocol (SIP), Skinny Client Control Protocol (SCCP) or various other proprietary protocols.

The Benefits of Using VoIP Technology
VoIP-based telephone technology offers Internet connection-based telephone technology with various advantages compared to the old conventional system. There are some tangible benefits when you use VoIP technology to communicate.

Easy to Install and Configure
One of the benefits of using VoIP technology is the ease of installation of this technology. Installation of this technology is quite easy and simple for those of you who have knowledge of mediocre technology. Instead of using a landline, you can install this technology application.

Offering Various Facilities
In addition, this technology also offers various facilities for this internet-based telephone. The first facility is speed dial, which makes it easy for you to make calls without pressing the number or numbers of the recipient. Limit duration is useful for limiting your phone time. Limit destination is also a good feature to limit the number of your phone destination. Meanwhile, the time limit is useful for giving a limit on how long the internet phone usage can be. The last facility is multi-password which is useful for managing phone users by password.

Even communication can be done between continents and countries. Surely you will feel much closer to your friends, family, and girlfriends who are far away.

Components and Software
VoIP Phone consists of hardware and software components. The software requires standard networking components such as a TCP/IP network stack, client implementations for DHCP, and the Domain Name System (DNS). In addition, VoIP signaling protocol stacks, such as for Session Initiation Protocol (SIP), H.323, Skinny Client Control Protocol (Cisco), and Skype, are required. For media flow, Real-time Transport Protocol (RTP) is used in most VoIP systems. For voice and media encoding, various encodings are available, such as for audio: G.711 , GSM , iLBC, Speex , G.729 , G.722 , G.722.2 (AMR-WB), other audio codecs, and for H video. 263 , H.263 + , H.264 . The user interface software controls the operation of the hardware components, and can respond to user actions with messages to the display screen.

STUN Client
To enable VoIP communication, SIP/RTP packets must be used and STUN client will be a key component for VoIP communication with SIP/RTP packet management. A Session Traversal Utility for NAT (STUN) clients is used on some SIP based VoIP phones as a firewall on network interfaces sometimes blocking SIP/RTP packets. Some special mechanism is required in this case to enable SIP packet routing from one network to another. STUN is used in some sip phones to enable SIP/RTP packets across the boundary of two different IP networks. A packet becomes unroutable between two sip elements if one network uses a private IP address range and the other is in a public IP address range. Stun is a mechanism to activate this border traversal. There are alternative mechanisms for NAT traversal, STUN is just one of them. STUN or any other NAT traversal mechanism is not required when two connected SIP phones can be routed to each other and there is no firewall in between.

DHCP Client
DHCP client software simplifies device connection to IP networks. The software automatically configures the network parameters and VoIP services.

How VoIP Phone System Technology Works
VoIP technology is able to convert various analog voices received directly from the speakers on the computer into data. Then, the data packet will continue the voice through the router with the help of the internet network to be received by the recipient of the call. The transmission of the signal to this destination must be done digitally, i.e. the voice is converted into digital data before being sent. Those are some things about Phone or VoIP technology.
