How to Edit a Picture Without Leaving Google Photos

It’s possible to edit your picture using Google Photos for desktop or on your mobile device. The available features will vary depending on the device your using. For example, the doodle feature is available for Android, but you won’t see it when you use Google Photos on your Windows computer.
Google Photos may not be a photo editing service that’s jam-packed with features, but it has some basic ones you can use. With a few clicks/taps here and there, you can do things such as add filter and doodle on your pictures (among other things).
You won’t be able to do things such as add stickers or remove the background, but some basic editing features are better than nothing. You never know, Google might add some more editing tools. Hopefully, it’ll be shortly.
How to Use Google Photos Editing ToolsIt’s possible to edit your picture using Google Photos for desktop or on your mobile device. The available features will vary depending on the device your using. For example, the doodle feature is available for Android, but you won’t see it when you use Google Photos on your Windows computer.
Additional OptionsAmong the editing options, you’ll also find a doodle option. While you can’t adjust the pen’s thickness, you can choose colors such as red, yellow, green, blue, purple, and white. The first option is your regular sized pen, while the one to the right is thicker but won’t completely cover any text.
If, at any time, while editing your text, you want to erase something, tap on the arrow pointing backward. If you like what you see, you can tap on the Done option at the bottom right. The square option of various dots will allow you to continue editing your picture in any other apps you have installed on your device.
You’ll also see a crop option where you can crop your picture in any way you want by dragging the dots on the corners. To help you be precise in cropping, Google Photos magnifies the area you’re dragging a specific corner.
When you think you’ve done all the editing you need, you can tap on the Save copy option at the top, or you can tap on the dots to undo any edits you’re not happy with after all.

How to charge a laptop without a charger

Since the beginning of time – or at least since the first laptopcomputer – laptops have shipped with a charger. Typically, these chargers are unique to their brands, and require an AC power source. But what if you don’t have access to AC power? If you need some vital information that’s stored on your laptop, a dead battery can effectively put your data out of reach. 

Every laptop is built with an internal battery. To get the battery charged, you’ve just got to supply it with some electricity. Most of the time, we plug our laptop into a power outlet in our home, and the electricity travels through the cable and into the battery.

A laptop charger is arguably the most effective way to transfer power to your laptop battery, but there are other ways to do it, too. All you need is:

A power source

A way to transfer the power to the battery

Use a USB Type-C Battery PackDepending on what model of laptop you own, you might be able to use a USB Type-C battery pack. While older USB Type-A ports only supported one-way power, USB Type-C ports support both inbound and outbound power. If your laptophas a USB Type-C port, you can use a USB Type-C battery pack, just like you’d use for your cell phone.

Use Your Cell Phone

As a last-ditch charging method in an emergency, most current smartphone models can be used as a backup power supply. Obviously, your smartphone battery doesn’t hold nearly as much charge as your laptop battery. This leads to a couple of significant drawbacks to the cell phone charging method.

Invest in a Universal Adapter
n this situation, a universal adapter might be the best answer to your problems. These are AC/DC adapters that come with multiple interchangeable tips, and they generally support a wide variety of brands.

And if you’re in the habit of losing things, you can usually buy individual tips to replace any that have disappeared. On some models, you can even connect to your car’s 12-volt cigarette lighter, which allows you to be truly mobile.

How to Troubleshoot Bluetooth Headphones on Android

Check the Bluetooth Pairing SettingsSometimes Bluetooth might simply be turned off on your phone or device. The icons that indicate whether Bluetooth is on or off can be difficult to see, or they might be hidden. If your device has a Bluetooth settings screen that allows fine control of Bluetooth behavior, you should ensure that Bluetooth is “connectable.” If your device does not have such a control screen, you can assume that the default behavior of the Bluetooth device is “connectable” and you don’t need to look for a way to enable this feature.
Turn it off and on againRestarting the affected device or devices, should almost always be your first troubleshooting step as it can fix a surprising number of issues. You should restart both your headphones and your phone for the best chance of this working.
Make sure Bluetooth is enabledA lot of phones have a quick access button to disable Bluetooth. Even though it’s unlikely, you should check your phone to make sure that you haven’t accidentally turned Bluetooth off in your pocket or bag.
Disconnect and reconnectTry disconnecting and reconnecting the Bluetooth connection between your phone and headphones. If that doesn’t work try unpairing them, then pairing them again.
Try different devicesThe best way to work out which device is causing the issue is to try them both with different devices. You should try connecting the Bluetooth headphones to another Bluetooth device, such as a computer as well as connecting your phone to another Bluetooth headset or speaker.
Recharge your devicesBattery power is obviously needed for both your phone and headphones to run. Check that they both have enough power. If your headphones don’t have a battery indicator, a few minutes of charging should be enough to identify if the battery charge was the issue.
Clear Bluetooth cache and dataIf none of these fixes work, you could try clearing your Bluetooth settings entirely. To do so, open the apps list in your phone’s settings app and tap on “Bluetooth”. If Bluetooth doesn’t appear in the list, you may need to enable “Show system apps”. To do so tap on the triple-dot icon in the top-right corner then select “Show system apps”.

Caring for the Camera and Battery: Cautions

Keep dry: This product is not waterproof, and may malfunction if immersed in water or exposed to high levels of humidity. Rusting of the internal mechanism can cause irreparable damage.
Do not leave the lens pointed at the sun: Do not leave the lens pointed at the sun or other strong light source for an extended period. Intense light may cause the image sensor to deteriorate or produce a white blur effect in photographs.
Turn the product off before removing or disconnecting the power source: Do not unplug the product or remove the battery while the product is on or while images are being recorded or deleted. Forcibly cutting power in these circumstances could result in loss of data or in damage to product memory or internal circuitry. To prevent an accidental interruption of po wer, avoid carrying the product from one location to another while the AC adapter is connected.
The lens and mirror are easily damaged. Dust and lint should be gently removed with a blower. When using an aerosol blower, keep the can vertical to prevent discharge of liquid. To remove fingerprints and other stains from the lens, apply a small amount of lens cleaner to a soft cloth and wipe the lens carefully.
The shutter curtain may appear to be unevenly colored, but this has no affect on pictures and does not indicate a malfunction.
To prevent mold or mildew, take the camera out of storage at least once a month. Turn the camera on and release the shutter a few times before putting it away.
Notes on the monitor: The monitor is constructed with extremely high precision; at least 99.99% of pixels are effective, with no more than 0.01% being missing or defective. Hence while these displays may contain pixels that are always lit (white, red, blue, or green) or always off (black), this is not a malfunction and has no effect on images recorded with the device.
Images in the monitor may be difficult to see in a bright light.
Do not apply pressure to the monitor, as this could cause damage or malfunction. Dust or lint on the monitor can be removed with a blower. Stains can be removed by wiping lightly with a soft cloth or chamois leather. Should the monitor break, care should be taken to avoid injury from broken glass and to prevent liquid crystal from the monitor touching the skin or entering the eyes and mouth.
The batteryand charger: Batteries may leak or explode if improperly handled. Observe the following precautions when handling batteries and chargers:
Use only batteries approved for use in this equipment. Do not expose the battery to flame or excessive heat.Keep the battery terminals clean.


How to repair lithium batteries ?What is the Lithium battery repair method ?

1. Use a clean eraser or other cleaning tool to gently wipe the metal contacts on the lithium battery and the metal contacts on the phone to help with the charging status and power lasting.
2. The old mobile phone lithium battery that will be automatically shut down will be wrapped tightly with plastic wrap. When wrapping, try to serve as much as possible. There are three layers inside and outside to ensure that the battery is in a vacuum state. Then, the three-layer newspaper on the outside of the plastic wrap is used to completely seal the lithium battery. After being placed in the freezer layer of the refrigerator, after 48 hours, the battery was taken out, and the six-layer paper film wrapped outside was removed one by one. The lithium battery was not swollen or deformed due to freezing. After cooling for a while, then charge.
3. Discharge the lithium battery that is nearly scrapped and recharge it to activate the battery. The specific method is: deep discharge of the mobile phone, by exhausting internal electrical energy, to achieve a deeper degree of recharging, which requires some unconventional methods. Connect the phone to a low-voltage small light bulb with a specific device, and the internal power of the battery will be transferred to the small light bulb until it is fully illuminated.
Electric vehicle lithium battery repair method
1. Re-matching: After the whole group of lithium battery packs are damaged, we often charge and discharge the electric vehicle lithium battery. In the inspection, it is often found that 50% of the batteries in a group of batteries are not damaged. The reason is that in the series-connected lithium battery pack, the function of the individual batteries behind the formation of the entire battery is degraded, so that the function of the entire battery is degraded.
2. Replenishment: For the electric vehicle lithium battery, the battery is replenished with water for about 4 months, which can prolong the service life of the battery and extend the average time to more than 3 months. It should be noted that after each replenishment, the battery is in an overcharged state to change the battery from a “pre-lean liquid” to a “lean liquid” state, and this over-charging is beneficial to increase the battery capacity.
3. Elimination of vulcanization: The battery repair equipment is used to eliminate the vulcanization treatment of the battery.
4. Particle generator: The particle generator is connected in parallel on the battery to repair the battery. This method is better for repairing lithium batteries for electric vehicles, but because the repair is more thorough, if there is no over-discharge, the continuous use of lithium batteries for electric vehicles often eliminates the possibility of battery vulcanization.
5. Comprehensive repair method for electric vehicle lithium battery pack: Regular inspection of electric vehicle lithium battery, timely desulfurization and hydration, single battery charging and re-matching. The battery description, if it is maintenance-free, generally does not need to add water.


How to Connect Your Android Tablet to a TV with an HDMI Connection

To connect an Android phone or tablet to a TV you can use an MHL/SlimPort (via Micro-USB) or Micro-HDMI cable if supported, or wirelessly cast your screen using Miracast or Chromecast. 
You may think that having a 10-inch Android tablet really smokes those folks with the smaller, 8-inch tablets. Ha! You’re in for a surprise. That’s because any tablet with HDMI output — even those doinky 7-inch models — can hook up to an 80-inch plasma HDTV screen and really show who’s boss.
When your Android tablet features an HDMI connection, whether it’s a 7-inch model or a 10-inch behemoth, you too can enjoy the pleasures of a larger screen. It doesn’t have to be an 80-inch plasma screen, either; any monitor or HDTV with HDMI input does the job.
Upon success, an HDMI notification or pop-up appears on the tablet’s screen. Choose it and select how to display information on the external monitor. Depending on the tablet, you can choose to run a slideshow, present videos or music, or simply mirror the information displayed on the touchscreen. Among the options you’ll find for using the larger screen are these:
Gallery: You can view pictures or a slideshow, according to the directions on the screen.
Music: Choose a playlist, an album, or an artist, and enjoy watching the Music app on the big screen. (The sound should play from the TV’s speakers.)
Mirror On Display: The screen output on your Android tablet is duplicated on the HDMI TV or monitor. This option is the one you choose when you want to watch a rented movie on the big screen.
When you’re finished using the HDMI connection, simply disconnect the tablet from the HDTV or monitor. The display returns to normal operation.

How to Update Your Android Tablet System

Before we get into upgrades, it’s important to know that some manufacturers are in the habit of adding different “skins,” or user interfaces, to whichever stock version of Android they’ve selected for a device. As a result, Ice Cream Sandwich, say, isn’t going to look or act the same across the assorted technologies you and your friends are packing. A manufacturer may tweak the operating system to work with a tablet’s cameras or interface with a cellular digital service. That’s what you get with an open source system. (But let it be said that there’s spirited debate among the Android community about whether all this customization is necessary or just plain ridiculous.)
Every so often, a new version of the Android tablet’s operating system becomes available. It’s an Android update because Android is the name of the operating system, not because the Android tablet thinks that it’s some type of robot.
Yes, you can put off an update by simply dismissing the update notice: Touch the Home icon. However, it is strongly recommended that you upgrade.
You can manually check for updates: In the Settings app, choose About Tablet or About Device. (On Samsung tablets, look on the General tab in the Settings app.) Choose System Updates or Software Update. When the system is up-to-date, the screen tells you so. Otherwise, you find directions for updating the Android operating system.
Touching the Check Now button isn’t magic. When an update is available, the tablet lets you know.
Non-Android system updates might also be issued. For example, the tablet’s manufacturer may send out an update to the Android tablet’s guts. This type of update is often called a firmware update. As with Android updates, you should accept all firmware updates.

How to Lock and Unlock Your iPhone

You can lock your iPhone so its touch screen doesn’t work. This prevents the iPhone from dialing phone numbers, playing music, or doing anything else when it’s in your pocket, rubbing against your pants, or in your purse making contact with keys and other stuff. Apple makes locking your iPhone a snap.
1.To lock the screen, press the Side Button
2.To unlock the screen, press the Side Button
3.If you have Face ID enabled, hold the phone at eye level and then swipe up from the bottom of the screen to unlock the phone
4. If you do not have Face ID enabled, press the Side Button
5.Swipe up from the bottom of the screen
6.If you have a passcode enabled, enter it now
You can set the passcode and the delay before the phone auto-locks from the Settings app.
If your phone is lost or stolen, you can use Find My iPhone to put the phone in Lost Mode, which locks the screen (even if you never set a passcode) and shows a message on the lock screen.
In fact, you don’t need to do anything to lock the iPhone; it happens automatically, if you don’t touch the screen for one minute.
Can’t wait that long? To lock the iPhone immediately, press the Sleep/Wake button. To unlock it, press the Sleep/Wake button again. Or, press the Home button on the front of the screen. Either way, the on-screen slider appears, but your iPhone doesn’t actually awaken until you drag the slider to the right with your finger.
