after installing new SD microcard I have this problem: cannot send ema
Rebooted no fix. Whats nexr to try? For sending email by phone? Gmail works on laptop. Sync error?? Says temp error? 2 days.
Gmail in this mobile can work without sdcard, have you 1) update you Gmail App, 2) remove your gmail account in setting or 3)factory reset of your mobile?
Did you format you micro sdcard in computer first?
Is it broken of golden finger in your microSD card slop? try to plug in other micro sdcard for test.
Hope you solve it!
