Hi Emilee, thank for yours answers!
1.) Could you kindly show me how do you find out the cell data connection is very slow?
Is there any comparison screenshots for our reference? ( In the same location)
Please also show me your SIM status screenshots when you encounter this problem.
(settings> system > about phone > status > SIM status)
There isn't any comparision screenshot but doing test with various providers (fast.com, speedtest.net, google speed test, etc) i can view the slow! The problem is fast but frequent and for this reason i can't show you information about my SIM!
2.) Thank you!
3.) What about it ?
4.) WiFi problem, Could your phone auto connect back by itself when wifi disconnecting?
Have you turned on the power saver? Does this problem occur even when you connect with a different router?
Please kindly go Settings> Connections > Wi-Fi >Press & hold [Net Work Name(SSID)] for 2 seconds >Select [Forget Network]>>Re-Connect your wireless.
Please try to reset the network settings to a check.
This problem occurs with a lots of routers. I had reset the network settings, the problem is still present!
5.) Thank you! Maybe it works now, i will update you!
6.)
Could the mobile signal re-connect back after disconnecting?
Is there any error message pop on while you encounter this problem?
Here're some tips for troubleshooting as below:
(1.) To turn on airplane mode > for 3 seconds > then turn off it.
(2.) To try to use another different sim card for a check.
If this problem still exists, please tell me your SIM carrier, and I've sent you a message, please kindly check your inbox.
I tried with another sim card, same problem! There isn't any messagge pop while i encounter the problem!
7.)
Does this problem happen when connecting to WiFi?
I would suggest you clear up your apps in the background, and restore the Google Play store for a check.
Please also free some memory via the mobile manager app.
The problem happens everytime, with all operations! Please help me to fix it, it is very problematic!
8.) The problem is now resolved!
9.) Do you mean self-photo saved rotate? I would suggest to can go gallery app > click your photo > edit > mirror.
The photos are saved horizontal instead of vertical! The program auto-rote the image!
Thank you.
