Displaying the text of messages on the screen of a smartphone when it is locked can be useful, but it can allow anyone to see your messages. Fortunately, it is possible to turn off this option in Telegram. Just go to the following path:
Settings »Notification and Sounds» Message Preview This feature is present in all versions of Telegram (even Telegram Desktop).
Telegram download management and internet saving
Having many Telegram friends along with membership in various groups and channels is one of the most important reasons that cause your internet usage to increase a lot and end as quickly as possible, but by removing a few ticks in Telegram, we can completely solve this issue. .
Another interesting trick of Telegram is the ability to change the phone number with which you have registered in Telegram.
The reason for the high consumption of the Internet in Telegram is the automatic receipt of images, videos and voice messages in groups and channels, while you may not want to see many of them. As a result, it is enough to prevent them from downloading automatically.
Enter Settings for this purpose. In the Automatic media download section, you will see three options that are related to setting this item in smartphone internet, wireless and internet roaming. Just enter any of your favorites and uncheck all options.
From now on, the received images and videos will be displayed as a preview, and you must click on them to view them in full. Clicking on it starts the file download process and you can view the desired image, video or audio message. With this small adjustment, you will see that your monthly internet usage decreases significantly.
Upload images without loss of quality
If you are careful, when you send an image in Telegram, the quality of the sent image automatically decreases, and in fact, the image that the recipient receives has a lower volume and, as a rule, a lower quality. Of course, this is an advantage that reduces the file size and as a result sends faster and consumes less internet, but sometimes you want to send an image to someone without losing quality. For this purpose, instead of sending a photo, just click on the submit file button (which has an icon that looks like a paper pin) and then send the photo you want to the contact through this way.
