Sharing on Android: how to transfer files, internet and screen in 5 minutes

Transferring data between devices has become an integral part of the everyday use of smartphones. However, not all users know how to properly set up Android has become an integral part of everyday smartphone use. However, not all users know how to properly configure sharing be it sharing photos via Bluetooth, distributing the Internet via Wi-Fi Hotspot or broadcasting the screen to a TV. In this article, we will look at all the current methods, including hidden functions and solutions to typical problems.

Modern versions Android 13/14/15 offer several built-in mechanisms for data exchange, but their settings are often hidden in the depths of the menu or require additional actions. For example, on devices with the Snapdragon 8 Gen 3 chip, Quick Share automatically selects the optimal protocol (Wi-Fi Direct or Bluetooth LE) depending on the file size and the distance between gadgets. We'll show you how to enable and optimize each of them.

1. Fast file transfer via Nearby Share (Quick Share)

Function Nearby Share (renamed to Quick Share s Android 14) is a universal solution from Google for exchanging files between devices on Android and even ChromeOS. It works through a combination of Bluetooth, Wi-Fi Direct and Hotspot, automatically selecting the fastest channel.

To activate it:

1. Open Settings → Google → Devices and sharing → Quick Share.
2. Enable the slider Use Quick Share.
3. Click Visibility settings and select All contacts or Only your devices.

To transfer a file:

• 📁 Open Google Files or Gallery, select the desired files.
• 🔗 Click Share → Quick Share.
• 📱 Select the target device from the list (it must be unlocked and within a radius of 10 meters).

Transfer speed depends on the protocol:

Protocol	Max. speed	Limitations
Wi-Fi Direct	up to 300 Mbit/s	Requires connection to the same network or creating a direct connection
Bluetooth 5.2	up to 2 Mbit/s	Suitable only for small files (<50 MB)
Hotspot (4G/5G)	up to 1 Gbit/s	Mobile network traffic consumption

⚠️ Attention: On devices Samsung s One UI 6.0+ function Quick Share may conflict with a proprietary solution Samsung Quick Share. To avoid duplication, disable one of them in the application settings Quick Share.

2. Setting up Wi-Fi Direct to transfer large files

Wi-Fi Direct is a technology that allows devices to connect directly without a router. It is ideal for transmitting video in resolution 4K or archives larger than 1 GB. Unlike Bluetooth, there are no restrictions on file size, and the speed reaches 250–300 Mbit/s.

Setting algorithm:

1. Activate Wi-Fi on both devices.
2. On the first device: Settings → Wi-Fi → Wi-Fi Direct (on some firmware the path may differ, for example Settings → Connections → Wi-Fi → Advanced → Wi-Fi Direct).
3. On the second device, follow the same steps and select the first device from the list.
4. Confirm the connection on both gadgets (you may need to enter a PIN code).

After connecting:

• 📤 Use any file manager (for example, Solid Explorer or FX File Explorer) to transfer data over a local network.
• 🔒 For security, disable Wi-Fi Direct after the transfer is complete - this will prevent unauthorized access.

Wi-Fi is activated on both devices|

Battery charge >30% (transmission consumes a lot of energy)|

Devices are within a radius of 5–7 meters|

VPN and proxies are disabled (can block connection)-->

⚠️ Attention: On devices with MediaTek Helio G99 and older chips, the connection may be broken when transferring files >2 GB in size. In this case, split the archive into parts or use FTP server via Hotspot.

3. Internet distribution via Hotspot: speed and battery optimization

Function Hotspot (access point) allows you to distribute mobile data to other devices. However, many encounter problems: low speed, rapid battery drain or automatic shutdown. Let's take a look at how to configure Hotspot correctly.

Basic settings:

1. Go to Settings → Network and Internet → Access point and modem → Mobile access point.
2. Enable the slider and configure the parameters:
   • 🔐 Network name (SSID): set a unique name (for example, MyAndroid_Hotspot).
   • 🔒 Password: use WPA3-Personal (if supported) or WPA2-PSK.
   • 📶 Range: select 5 GHz for higher speed (but smaller radius) or 2.4 GHz for better compatibility.

To save battery:

• ⚡ Turn off Hotspotwhen not in use (there is an option to automatically turn off after 5-30 minutes without activity). Android 14+ There is an option to automatically turn off after 5–30 minutes of inactivity).
• 🔋 Turn on the mode Battery saving (will limit background activity).
• 📴 If speed is critical, connect your smartphone to a charger - this will remove battery restrictions performance.

On some firmware (for example, MIUI 14 to Xiaomi) there is a hidden option Improved modem, which increases the speed by 15-20%. To activate it:

Enter in the phone app: ##4636## → Select "Phone Information" → Scroll down to "Set preferred network type" → Select "LTE/5G only"

4. Transferring files via Bluetooth: when justified

Bluetooth is inferior in speed Wi-Fi Direct, but remains useful for transferring small files (up to 50 MB) or exchanging contacts. The main advantage is low power consumption and operation at a distance of up to 10–15 meters (in the case of Bluetooth 5.2+).

How to set up:

1. Turn on Bluetooth on both devices: Settings → Connected devices → Connection settings → Bluetooth.
2. Make one of the devices Visible to everyone (usually the time limit is 2-5 minutes).
3. On the second device, find the first one in the list and pair (confirmation code may be required).

To transfer a file:

• 📎 In the file manager, select the file → Share → Bluetooth.
• 📱 Select the target device from the list.
• ✅ Confirm reception on the second device.

Limitations and solutions:

Problem	Cause	Solution
The file is not sent	The size is too large (>50 MB)	Use Wi-Fi Direct or split the file into parts
Slow transmission	Outdated version of Bluetooth (<4.0)	Update the firmware or use an adapter Bluetooth 5.0
Constant disconnections	Interference from others devices	Turn off microwaves, wireless headphones and other sources of interference

Why is Bluetooth 5.2 faster than previous versions?

Bluetooth 5.2 supports the LE Audio protocol and LE Power Control technology, which dynamically adjust signal strength. This reduces interference and increases throughput up to 2 Mbit/s (versus 1 Mbit/s in Bluetooth 4.2).

5. Screen sharing: Miracast, Google Cast and alternatives

Screen broadcast from Android to a TV or monitor is implemented through several protocols: Miracast (built into most TVs), Google Cast (for Chromecast i compatible devices) and proprietary solutions like Samsung DeX or Huawei Cast+.

General algorithm for Miracast:

1. Make sure that the TV supports Miracast (usually this is indicated in the specifications or menu Source → Screen Mirroring).
2. On a smartphone: Settings → Connected devices → Connection settings → Screen casting.
3. Select the TV from the list and confirm the connection.

For Google Cast:

• 📺 Make sure that Chromecast or Android TV are connected to the same Wi-Fi network as your smartphone.
• 🎥 In a supported application (for example, YouTube or Google Photos) click the icon Cast (📡) and select the device.
• 🔄 To broadcast the entire screen: Settings → Google → Devices and sharing → Broadcast screen.

⚠️ Attention: On devices with Android 13+ chip Exynos 2200 there may be a delay in sound when broadcasting via MiracastSolution: enable in the developer settings (Settings → About phone → Build number → 7 taps). option Disable absolute audio delay.

6. Alternative methods: FTP, NFC and cloud services

If standard methods are not suitable, consider alternatives:

FTP server via Hotspot:

• 📡 Install the application FTP Server (for example, Solid Explorer or FX File Explorer).
• 🔌 Connect your smartphone to the PC via USB cable or activate Hotspot.
• 🌐 Launch the FTP server in the application and connect to it from the PC at the specified IP address (for example ftp://192.168.43.1:2221).

NFC (for small files):

• 📱 Make sure that both devices support NFC and the function is enabled (Settings → Connected devices → NFC).
• 🔗 Place the devices back to back (distance <5 cm).
• 📤 Select a file to transfer (usually only images and contacts are supported).

Cloud services (for remote access):

• ☁️ Upload files to Google Drive, Dropbox or Telegram Saved Messages.
• 🔗 Generate a download link (click Google Drive Share → Copy link Share → Copy link).
• 📲 Send the link to the recipient via messenger.

7. Solving typical problems when sharing.

Even with proper setup, errors may occur. Here are the most common ones and how to fix them:

Problem	Possible cause	Solution
The device does not see another device via Wi-Fi Direct	Different Wi-Fi standards (for example, 802.11ac vs 802.11n)	Enable compatibility mode in the router settings 802.11n/ac/ax
