I got my phone on Tuesday and it's in flawless condition. The wifi has been working fine at home and at work. Starting last night it only has one bar of wifi. My laptop has a full signal. Is there an issue with the phone??
Mine randomly does that too, but I doing some speed tests show now degradation in speed. It might be a glitch in how the software reports signal strength, but so far nothing has led me to believe it's a real problem. It'll probably be fixed in the next software update.
