For the past week (seems to have started since I returned from a trip abroad), all data comsuming apps on my phone are unusable. I can barely listen to a radio stream on tunein without it flaking in and out every 20 seconds. Weird thing is if I switch on the wifi hotspot and connect using a tablet its business as usual on the tablet - very fast. I just did a 4G speed test on the phone and got down=14Mbps, up=4Mbps. I have tried reconnecting to the network multiple times and even did a factory reset. Anyhow the problem is obviously not the data connection but the device, Any idea what could be the issue? It's across all data comsuming apps on the phone e.g. Chrome, Firefox, Play Store. Thanks
