High mobile data consumption

Hi,

I experienced high and excessive mobile data consumption on a Samsung and a Huawei device.

Jami was used on both devices for about 3 hours. Less than 15 text messages were exchanged between both devices. On both devices the 'share location for 1 hour' function was enabled twice.

The Samsung device moved often between outside locations with good mobile network reception and underground locations with poor mobile network reception (I used the metro a few times). The Huawei device remained outside with permanent good mobile network reception.

On both devices, Jami was used without WiFi for the first time.

Samsung:

• Galaxy A52 with Android 12
• Jami 'Taranis 20220311-01', installed via F-Droid
• DHT Proxy function enabled

Huawei:

• Jami, version unknown, installed most likely via Google Play Store
• DHT Proxy function setting unknown

After 3 hours, the devices showed the following data consumptions:

• 340MB on the Samsung device
• 9,5GB (It's indeed Gigabytes) on the Huawei device

Can I provide any other information from the Samsung device that helps to track this issue down?
