How to make latest pen drive (like 3.2 gen 1) to work both in Android phone and in Android TV?....copy and paste this blog post in your email and send it to yourself. I will delete this blog on February 1 2026
In old USB 2.0 pen drives, you can load movies from an Android phone using an OTG cable, and the movie will play on any TV with a USB port.
However, you cannot transfer movies quickly from an Android phone to a USB 2.0 pen drive. If you transfer a total of 10GB of movies from the phone to that USB 2.0 pen drive, it will take a long time... it will test your patience.
A basic OTG cable costs 40 to 80 rupees and is available in electronics shops. If you buy a Belkin OTG cable on Amazon, it is 1300 rupees... they say it supports up to USB 3.0 pen drives. Even if you use that for a USB 2.0 pen drive, you cannot transfer data quickly from the phone to the USB 2.0 pen drive.
USB 3.2 Gen 2 pen drives have arrived to transfer movies quickly from Android phones. There are two types: Ordinary 3.2 Gen 2 pen drive and OTG type 3.2 Gen 2 pen drive. You don't need to buy an OTG wire separately for the latter. One end will have the OTG part, and the other end will have the pen drive part. If you buy one, buy the OTG type pen drive, whether it is 3.2 Gen 2 or 3.2 Gen 1.
We have a TCL Google TV at home. I had a doubt whether the latest USB 3.2 Gen 2 pen drive would work on it or not. Nevertheless, thinking "let’s buy it anyway," I went to Reliance Digital. It wasn't there. Instead, they had the older 3.2 Gen 1 pen drive (OTG type). The 64GB version was 928 rupees. I bought it. It is this:

On its cover, it said "up to 300 MB per second read." I asked Gemini AI about the difference between "Read Speed" and "Write Speed" regarding pen drives. It told me the following:
1. What is "Read Speed"?
✅ Read Speed refers to how fast your pen drive or flash drive provides files to your computer (PC) or mobile phone for viewing, using, or copying (Copy From Pen Drive to PC/Phone).
💻 Read Speed in daily use:
Here are some "Read" actions that happen every time you use a pen drive:
* Opening a file: When you open a large movie file or document directly from the pen drive, this read speed determines how quickly that file is sent to your computer and displayed on the screen.
* Copying Out: When you move a 1 GB video from the pen drive to your computer's hard drive, the read speed is how fast the pen drive provides that 1 GB of data. (This is where your 130 MB/s speed comes in).
* Previewing images: When you scroll through many photos on the pen drive, how fast each image loads also depends on this speed.
In short, this 300 MB/s Read Speed will be useful for any operation that takes data out of the pen drive.
2. What is "Write Speed"?
✍️ Write Speed refers to the speed at which information (Data) is saved or recorded into a storage device, i.e., your pen drive.
* Action: This is the process that happens when you copy or move a file from your computer or mobile to the pen drive (Copy to Pen Drive).
* Direction: This is always in the direction of Computer/Mobile -> Pen Drive.
* Measurement: Like read speed, this is also measured in Megabytes per second (MB/s).
Key Difference:
In pen drives, the Write Speed is generally much lower than the Read Speed.
For example:
* Read Speed: 300 MB/s
* Write Speed: might be between 30 MB/s to 40 MB/s.
* Summary: If you want to save large files (movies, many photos) to your pen drive, it is this Write Speed that determines how quickly that task will finish.
Because this write speed is lower than the read speed, it isn't "attractive." To avoid failing to attract customers, they only print the read speed on the pen drive packaging.
I transferred movies from my Android phone to the pen drive I bought. The default File Manager app on Android does not show the write speed while moving files from the phone to the pen drive. If you want to see the write speed directly while the file is transferring, you should use the ZArchiver app. This app is a file manager app. It is a "must-have" app on your Android phone.

Other uses of ZArchiver app:
* ZArchiver app shows write time while the movies are being transferred from Android phone to pen drive.
* Using ZArchiver you can retrieve subtitle file which is present within a zip file.
* You can create a notepad file in any folder in Windows computer. Similarly in Android phone you can create individual notepad file in any folder using ZArchiver app. There is no other app in Android which allows you to create a notepad file in any folder in Android phone.
* If you cut and paste a 1 GB file from one folder to another folder using default file manager app it will take some time. But ZArchiver transfers it without taking any time.
* The final use of ZArchiver app is very important. There is a format called FAT32. If you have formatted your pen drive in FAT32 (using Windows computer), you cannot transfer an individual video of size above 4GB from Android phone to pen drive using any file manager app (including ZArchiver file manager app). Also, let us assume if a folder in Android phone has 10 videos each of which is 1GB size. Total folder size is 10GB. Even if your pen drive is formatted in FAT32 format, you should be able to copy and paste this folder to your pen drive because individual videos' sizes are within 4GB. But the default file manager in many Android phones will mistakenly consider that total 10GB folder as a size above 4GB and will not copy and paste that folder to the pen drive. But if you use the ZArchiver app file manager, it will copy and paste that 10GB folder to the pen drive.
When I plugged my pen drive into my Android phone, it showed "Format." I pressed it. It formatted it for me. The file system it formatted was exFAT (I checked this later on a computer). I transferred movies from the phone to the pen drive. When I plugged it into the TCL Google TV, it showed the pen drive was "corrupt." I told Gemini. It told me to plug the pen drive into a Windows computer and format it to the FAT32 file system. This is because the FAT32 file system is the only one that works on both Android phones and Google TVs.
There was a problem with that too. Windows computers only show the FAT32 option when formatting pen drives up to 32GB. My pen drive is 64GB... when I tried to format it in a Windows computer, it didn't show FAT32.
Gemini taught me some Command Prompt steps. It said that by using those, any size pen drive could be formatted to the FAT32 file system.
It also said if that didn't work for me, I could use certain software to format it to FAT32 without any trouble. It gave me 2 software names:
* AOMEI Partition Assistant Standard
* MiniTool Partition Wizard Free Edition
If you don't know how to use these softwares to format pen drive in FAT32 file system, search videos in YouTube. But I didn't watch any YouTube video. I went to a computer sales shop.
The lady there said there was no power and asked me to come back later. I went back later. A person with a beard was there; he seemed to be the owner's son. He said, "If you bought it at Reliance Digital, you should give it there for service." (There were many pen drives for sale in his shop too). He said there might be a virus in the pen drive. He took a separate laptop and tried using the Command Prompt himself. He couldn't do it. He said it couldn't be changed using Command Prompt. After that, using the software he had, he changed my 64GB pen drive from exFAT format to FAT32. He didn't take any money when I left. But he told me, "In the future, buy pen drives from a shop that provides service. The people at Reliance Digital won't know about these things if you ask."
After coming home, I told Gemini that he couldn't change it via Command Prompt. It pointed out the mistake he might have made. It said he probably failed to enter a specific number and told me that number.
We don't need all that. If you have a computer, use the software mentioned above to format the pen drive to FAT32.
In a pen drive formatted in FAT32, if a single individual movie is over 4GB, you cannot upload it from the phone to the pen drive. Each of our personal movies is at most 2GB. So, this is not a problem.
Furthermore, let’s say we have 10 movies in a folder on an Android phone, each 1GB. Total 10GB. If you move this to the pen drive using the default File Manager app on the Android phone, it will show an error. Gemini AI explained the reason for this too. That is, when moving files to a FAT32 formatted pen drive, if the default File Manager works correctly, it should only block the specific large files that are over 4GB. But the default File Manager on my Android phone functioned incorrectly. It saw the 10GB folder as a single individual file and said, "This is a FAT32 format file over 4GB; it cannot be transferred." Gemini told me to try other file manager apps from the Play Store. I already had the ZArchiver file manager app. Using that, I wrote 10GB of movies from the Android phone to my pen drive at once.
ZArchiver app showed the write speed of my 3.2 Gen 1 pen drive. It was fluctuating between 14MB/s, 15MB/s, and 20MB/s. It showed 15MB/s steadily for the longest time. That is the write speed of my pen drive.
This means if you buy a 3.2 Gen 1 pen drive, you can transfer a 1GB movie from your phone within 1 minute and 6 seconds.
FAT32 format pen drive (USB 3.2 Gen 1) works well both in Android phone and in Google TV.
Web Video Cast App and Web Video Cast Receiver App:
Install Web Video Cast app from the Play Store on your Android phone and Web Video Cast Receiver app on your Google TV from its Play Store.
play.google.com/store/apps/dev?id=6953873961894982344
Say "Google Play" into the mic on your Google TV. Then the Play Store page will open. You can download Web Video Cast Receiver from the Google TV's Play Store. These 2 apps work together. If you have a modem in your home, the WiFi must be the same on the Android phone and the Google TV.
If you don't have a modem and only have internet on your phone, turn on Data and Hotspot on the Android phone. Turn on WiFi on the Google TV.
Then use both these apps. You can cast videos from the Android phone to the Web Video Cast Receiver app on the Google TV. If you hate advertisements, pay 1300rs... buy Web Video Cast from the Play Store... lifetime validity. Apart from casting videos from your Android phone, you can cast videos from websites on your Android phone to the Web Video Cast Receiver on Google TV using these 2 apps. Using these 2 apps, I directly cast videos from sites from my phone to Google TV. I have even stopped downloading and using the pen drive. Downloading videos takes space on the phone. Also, I would need to buy an external SSD hard disk later to save those videos... so I stopped downloading. But I haven't bought the Web Video Cast app premium until now. I am using it now with advertisements. But I will buy it in the future. I don't have an ATM card now. Seeing advertisements in the Web Video Cast app frequently is irritating...
