I have some questions about Android smartphones.
1. Do all Android phones have an option to change the WiFI hotspot channel, so if there is a problem with WiFi interference when tethering, you can change the channel, or do only certain phones have this feature?
2. Is there much speed difference between 3G and 4G? For instance, if you sometimes experience buffering watching HD programmes in 3G, do you not get buffering in 4G? So in other words, is buying a 4G smartphone worth the extra cost.
