Troubleshoot: Pen drive not detecting in Android

When there were only windows OS laptops and Symbian operated mobile phones, we had to transfer the files from pen drive to PC and then to mobile phone by means of USB connecting cable.

But, Once Android entered into the game, the scenario changes.
We can directly connect the Pen drive to Android smartphones by means of OTG (On the GO ) cables and transfer the files directly.

Even though we can directly connect the USB drive directly to the phones, lot of us are facing difficulties to transfer files through this method.

The following troubleshooting method might help you to spot out the issue and let you to solve it and transfer your files from Pen drive to Android smartphone and Smarphone to Pen drive easily.


Method 1 :

Ensure that your pen-drive is formatted using FAT 32 method. If it is formatted using NTFS method, then Android phones could not detect your pendrive.

You can check it by inserting the Pen drive in some laptops or PC and to check it in the properties.

Solution is to copy the data in local drive, reformat into FAT 32 method, recopy the file and connect it to the Android device.

Method 2:

• Root your Android phone
• Install NTFS mounter app in your phone
• Connect the pendrive with your android device
• Transfer the data

Method 3:

Check whether your mobile phone has the capability to connect with USB drive. Some classic old modeled Android devices do not support OTG cabled USB drive connection.

In Dual SIM smartphone, only one SIM slot can be activated with high speed internet or WCDMA means (Wideband Code Division Multiple Access) . In some smartphones, it is interchangeable. But in some smartphones, primary sim is WCDMA / GSM and secondary sim is only for GSM (low speed internet  connection like 2G, EDGE)

If it is clearly provided that  SIM 1 Slot is for WCDMA and SIM 2 Slot is of GSM type, then this procedure will not work most probably.

The only solution is to swap (Change the sim cards between the slots and use your desired 3G sim card in Primary SIM 1 slot.

Mostly dual SIM phones with high end specifications has this 3G Switching option and phones in low entry level market doesn’t have this switching option and they have primary SIM as 3G and Secondary SIM as 2G

If you hope that your phone specification has both slots can be used as 3G then we can proceed further.

Here we have to note that at same time we can’t enable 3G in both SIM slots.

How to set sim2 as wcdma:

So, If you want to convert Sim 2 Slot into 3G, you have to set SIM 1 slot as GSM, then set SIM 2 slot as WCDMA or 3G

Likewise if you try to convert SIM 1 as 3G, set SIM 2 slot as GSM first and then enable WCDMA in SIM 1 Slot.

It is better to plan accordingly in which SIM card, you are going to browse high speed internet mostly, then FIX that simcard as a Primary SIM card Slot.

Changing it often may result in confusion and it may also result  in unnecessary loss of talk time.

Will GSM sim work in WCDMA slot ?

Yes, GSM sim will work in WCDMA slot. But the internet browsing speed will be according to 2G speed of the network provider
