Those of you lucky enough to have your devices in hand, how is your signal? My signal has gotten worse over the past year. I still have the 6. I've complained to T-Mobile a few times about it. I'm not ready to switch to another provider yet because I like having unlimited data. I use about 15gb/month.. Do you notice your phone keeping a signal better? Mine periodically switches to 4g and then the data comes to a screeching hault. I didn't have as many connection problems g before. I'm not sure if it's my device or the service. Do you notice major performance differences between your 6s and the 7?
