The smart watch YouTube Music app is only compatible with Google Wear OS 3, not compatible with the old version

 Google’s Wear OS 3, an operating system designed specifically for smart watches, has been officially launched for the Samsung Galaxy Watch 4 series. The system is based on the Android 11 kernel and can install a variety of exclusive apps such as calendar, maps, Google Pay, and Gmail. According to GSMArena news, some overseas users tried to extract the YouTube Music in the information supply, and wanted to install it to the old version of Wear OS 2, but the results showed that it was not supported.

This user tried to extract the apk file in Galaxy Watch 4 and copy it to the Moto 360 watch and forcibly install it, but the ADB command returned an error stating that the app requires Android 11 or higher.
It is learned that Google previously stated that it will decentralize some Wear OS 3 functions to Wear OS 2 devices, including improved messaging applications, Google Play expansion deployment, and so on. Some media said that the current third-party streaming music application Spotify has supported Wear OS 3 and Wear OS 2 at the same time, as well as online and offline playback. At present, the application has been adapted to many smart watches such as TicWatch and Moto 360Samsung Batteries – Shop a wide selection of Google Batteries at Fast Shipping.

What is the difference between Samsung Galaxy Z Fold 3 and Samsung Galaxy Z Fold 2?

From an aesthetic point of view, there is almost no difference (if any) between Galaxy Z Fold 2 and Galaxy Z Fold 3. They all fold inward and have two screens, one folds up and the other device on the outside. Because the standard when the Galaxy Z Fold 2 is opened is 195.2×128.2×6.9 mm, the standard when folded is 159.2x68x13.8 mm, and the standard when opened is 159.2×128.1×6.4 mm, and the standard when folded is 158.2×67.1×14 mm, so the standard is slightly lowered. The weight of the new version has been reduced by about 10 grams, but it still weighs 271 grams on the scale. According to Samsung, it is also waterproof, while the Galaxy Z Fold 2 does not, and it provides a more stable structure.

Higher refresh rate and S Pen supportRegarding the screens, they have the same diagonal, which is 6.23 inches on the outside and 7.6 inches on the inside. The latter is still compatible with HDR10+, but adds support for the S Pen (Samsung‘s stylus for taking notes or drawing). However, within the range of the manufacturer’s Galaxy Note, there is no Bluetooth to prevent remote operation. The internal display still benefits from a 120 Hz refresh rate, which is the same as the Galaxy Z Fold 2, but the version 3 also supplies 120 Hz on the external screen, which is different from its predecessor, which is limited to 60 Hz. The top of the main (inner) screen is different, because there is a camera under the device, and under the Galaxy Z Fold 2, there is a punch that can transmit the scene to the sensor located at the back.

IPhone 13 may use a new camera assembly method, Apple produces its own components

According to The Elec report, Apple will change its camera module production process. The report explains that Apple usually buys pre-assembled camera modules from its suppliers and then assembles them into smartphones. But the current approach is different.


  Elec reported that a South Korean supplier, Hyvision System, will provide Focconn with “camera module inspection equipment.” This type of device is used to check the axis alignment of various camera sensors. This indicates that Apple will no longer use fully assembled dual-camera and triple-camera modules, but will purchase a separate camera sensor and produce its own components.
   According to reports, Apple has ordered enough components from its suppliers to produce 90 million iPhone 13. Elec pointed out that this is 20% higher than the number of iPhone 12 ordered. This change may also be due to shortages and delays in the supply chain. Apple admitted in its latest quarterly earnings conference call that the shortage will affect Apple’s revenue in the next quarter.


   Judging from the current news, the camera design of the iPhone 13 series is not much different from that of the iPhone 12 series, and both adopt a “big circle” design. The iPhone 13 series will still have four models, including iPhone 13 mini, iPhone 13, iPhone 13 Pro and iPhone 13 Pro Max. The reason why Apple changed the camera assembly method may be to prevent breaking the news. Of course, this is just a guess.You can buy laptop batteries on

What to do if you forget the lock screen password on your iPhone two ways to unlock the lock screen password

The iPhone lock screen password can’t be remembered suddenly, or the password is forgotten, how can we solve it? The following will teach you two methods without going to the after-sales service.
Method 1: Erase iPhone via iCloud
Tutorial steps:
1. Use your own or a friend’s Apple device (such as iPhone or iPad) to open the “Find iPhone” application. Note that the “Find iPhone” mentioned here is an application, not the “Find My iPhone” feature in the settings.
2. Log in your Apple ID in the “Find iPhone” application, and then we can view your device. Next, we need to choose to erase all data. In this step, it is very important that you never choose to remove the device or lock the device.
3. Do not turn off the iPhone when erasing data, and make sure that there is a SIM card in the iPhone, that is, we need to ensure that the iPhone is in a state of network connectivity.
4. At this time, we will find that the iPhone that has forgotten the lock screen password prompts you to reactivate the phone.
5. Next, all we need to do is to enter our Apple ID and set it as a new iPhone.

Method 2: Use iTunes to restore
If you cannot use iCloud to restore, you can try to restore the phone using iTunes. After the restoration, the data in the phone will also be erased.
Operation steps: Turn off the phone and connect it to the computer, and then enter the DFU mode. After entering, iTunes will tell you “Your iPhone has a problem and needs to be updated or restored”, just click the “Restore” button.You can buy laptop batteries on

What to do if the iPhone battery is attenuated? A few knowledge about battery health

Recently, more and more Apple users have found that the battery health is falling a little faster, especially for the iPhone 12 series. Here are a few knowledge about battery health.

1. Fast charging may accelerate battery consumption
This year’s iPhone 12 all support 20W fast charging. However, many small partners have suggested that after using fast charging, the battery capacity of iPhone 12 will drop by 2%-3% in a short period of time! So the question is, will fast charging cause damage to battery health? The answer is: yes! But the impact is not great.
When using fast charge, due to the high current, the thermal effect will cause the battery to generate high temperature, and the high temperature is the culprit that causes the rapid decline of the battery capacity. Therefore, for those who are accustomed to using wired fast charging, it is strongly recommended that you use Apple’s official (or MFi certified) charging head and data cable to minimize battery loss.
Second, high temperature is the culprit in accelerating battery loss
Here is a special reminder that you should never put your phone on the bed, sofa or any other place that is not conducive to the heat dissipation of the phone while charging. Do not use the phone for navigation while fast charging in the car in the summer. If you must do this, be sure to use the air conditioning vent mobile phone holder and use it when the air conditioner is turned on, so that at least the phone can be kept at a suitable temperature.
In addition, for mobile game players, you can consider adding a cooling fan to your mobile phone. It is also very effective to test the heat dissipation effect.
Three, choose MagSafe magnetic charging treasure carefully
MagSafe magnetic charging treasure may also cause the iPhone 12 battery to decay faster.
At present, there are various kinds of magnetic charging treasures on the market, but these products that claim to be compatible with MagSafe are almost all informal “MagSafe compatible” and are not officially certified by Apple. Many of these third-party products have problems such as severe fever, unreliable quality, and no after-sales guarantee. So, if you really need a MagSafe magnetic power bank, Apple’s latest external battery is currently the only officially certified MagSafe battery accessory.You can buy laptop batteries on

Another company abandoned Qualcomm chips, Google will independently develop chips for new mobile phones

Mobile phones have basically become an indispensable item in each of our lives. It covers many aspects of our work, study, entertainment and so on. The chip industry, which provides one of the most important components for mobile phones, is naturally also the current sweet potato. Recently, Google said that it will independently develop new mobile phone chips.

   According to reports, Google announced on Monday that it will develop its own smartphone processor “Google Tensor” for use in the new Pixel 6 and Pixel 6 Pro to be released this fall. In this regard, Qualcomm said that it will continue to work closely with Google on existing and future products based on the Snapdragon platform.

   It is understood that this time Google’s self-developed mobile phone chip will also use the ARM chip architecture. This architecture chip has lower power consumption and can naturally bring higher performance. Google officially stated that this is a complete system-level chip that can significantly improve the photo and video processing, translation and other functions on the phone.
   Now more and more smart terminal manufacturers are gradually “abandoning” traditional chip manufacturers in order to develop their own processors. This is the case with the latest Mac computer released by Apple. It abandons the Intel chip it has been using before, but is equipped with a self-developed M1 processor.You can buy laptop batteries on

There is a 3.5mm audio jack on the top of the phone and a USB Type-C port, speaker and microphone grille on the bottom. There is a power button, an alarm slider and a camera shutter button on the right side of the phone, and a volume up and down buttons on the left side of the phone.

   It is worth mentioning that the rendering is just a “concept presentation” of OnePlus Nord 10 Pro. In fact, the design of the phone may be completely different. It is expected that in a few months, we will be able to see the actual rendering of this phone.You can buy cell phone batteries

Some media exposed Apple’s chip roadmap to release a variety of new Mac products in 2022

Thanks to a good user experience, Mac products equipped with Apple Silicon have been recognized by many consumers. Recently, some media exposed Apple Silicon’s roadmap and forecasts of Mac product planning in the next year. According to the media, Apple will launch a brand-new MacBook Pro this year and a high-end version of the Mac mini soon.

   Earlier, Apple stated at the 2020 WWDC conference that it would take two years to switch all its Mac products to Apple Silicon. Now, except for the Mac Pro product line, other product lines have been converted. It is understood that Apple will most likely launch a Mac Pro equipped with a self-developed chip in 2022, but before the product is unveiled, Apple will still launch a Mac Pro with a built-in Intel chip.

   In addition, Apple will also launch a newly designed MacBook Air in 2022. The new MacBook Air has a richer I/O interface, and the charging port will also be changed to MagSafe magnetic charging. This design can ensure that even if the power cord is kicked in daily use, it will not cause the Mac to fall, reducing the risk during use.You can buy cell phone batteries
