Android handles large files well. The built-in file manager gives you direct access to storage. Chrome uploads work reliably. The challenge is finding a delivery method that does not compress your video or ask your client to log in somewhere.
Here is the method that works.
Why the default Android methods fail
WhatsApp: Compresses video automatically. A 4K export sent via WhatsApp arrives as a reduced-quality file. Unusable for client delivery.
Gmail: Has a 25MB attachment limit. Large video files cannot be sent as attachments.
Google Drive share link: If your client has a Google account and is signed in, this works. If they use Apple devices, Outlook, or have no Google account, they are asked to sign in. Brand clients and agency contacts often refuse.
Bluetooth: Range-limited. Not suitable for remote delivery.
Nearby Share: Same limitation. Requires both devices to be nearby.
The method that works from Android
Upload from Chrome on Android to a web-based delivery tool. Share the link. Your client downloads the original file from any device, no account required.
Step 1: Locate the file on your device
Open your file manager app. On Samsung devices this is My Files. On stock Android this is Files by Google. Navigate to the folder where your video export is saved.
Video files edited in CapCut, DaVinci Resolve, or exported from camera apps are usually in DCIM, Movies, or a folder created by the editing app.
Confirm the file name and size before uploading.
Step 2: Open Chrome and go to your delivery tool
Open Chrome on your Android device. Navigate to your delivery tool. On TrunkTransfer, the upload widget is on the homepage.
Tap the upload area. Chrome shows a file picker. Navigate to your file manager and select the video file.
Step 3: Upload the file
The upload starts immediately. Keep Chrome in the foreground while the file uploads. Android may throttle background network activity when the browser is minimized during a large upload.
Use Wi-Fi rather than mobile data when uploading files above 1GB. Upload speed on Wi-Fi is significantly faster than LTE in most environments.
Step 4: Copy the delivery link
When the upload completes, the delivery link appears on screen. Tap and hold to copy it, or use the copy button.
Step 5: Share the link with your client
Paste the link into your email, WhatsApp text message, or Slack. Your client opens the URL in any browser on any device and sees a download page. They tap Download and get the original file.
No account. No app. No compression.
Tips for large uploads on Android
Stay on Wi-Fi. A 5GB file on LTE takes considerably longer than on a fast Wi-Fi connection and uses significant data. Connect to Wi-Fi before starting large uploads.
Keep the screen active. Android's battery optimization may reduce network activity when the screen turns off during a long upload. Set screen timeout to a longer interval or keep the screen on while uploading.
Disable battery saver. Battery saver modes on Android throttle background processes and network activity. Turn it off before starting a large upload.
Use Chrome, not Firefox or Samsung Internet. Chrome on Android has the most reliable file upload behavior. Other browsers can have inconsistent behavior with large file uploads from the file picker.
Uploading footage shot on Android
Modern Android phones shoot in high-resolution formats that produce large files. Samsung S-series and Google Pixel phones shoot 4K at 60fps, producing files of 1 to 3GB per minute of footage.
If you are delivering raw or edited footage shot on an Android phone, the same upload method applies. The file manager gives direct access to the DCIM folder where camera footage is stored.
After the upload
Set a 30-day expiry on links going to brand clients and agencies. They share links internally, and someone will need the file two or three weeks after you sent it.
Enable download notifications. You will receive an email the moment your client clicks Download. If you are delivering from location and cannot follow up easily, this notification confirms the delivery is done.

Frequently Asked Questions
Can I send a large video file from Android without installing an app?
Yes. Use Chrome on Android to upload directly to a browser-based delivery tool. No app required. Your client also does not need an app to download.
Why does WhatsApp compress my video?
WhatsApp applies compression to all video to reduce message size and delivery time. This is intentional behavior for casual messaging. For professional file delivery, always use a file delivery link.
How large a file can I upload from an Android phone?
The limit depends on your delivery tool, not your phone. TrunkTransfer supports up to 200GB per transfer. The practical limit on mobile is your available storage and connection speed.
What Android file manager should I use?
Files by Google works on stock Android. Samsung devices include My Files. Either gives you access to all storage locations. Avoid file managers that open files in their own viewer rather than offering them to Chrome for upload.
Does this work on Android tablets?
Yes. Chrome on Android tablets behaves the same as on phones for file uploads. If you are editing on a Samsung Galaxy Tab or similar device, the same workflow applies.
