phone drops network connection

[rayvin400]

I don't really know what to do. Up until 3 weeks ago I didn't have this issue. Every time I'm traveling around my area there are certain areas where the phone will just lose all network connections. This happened before, however now the phone will not pick the connection back up unless I restart the phone (Ive waited for hours, to see if it would pick it up again on its own). Every time I restart it, the connection is fine and working.

Hi @rayvin400,

If it is only dropping in certain areas it is most likely due to the the network. I recommend you try another SIM card in your phone and check with your network to see if those areas are poor signals.

In your Settings > More > Mobile Networks > Preferred network type, make sure you are set to LTE Preferred.

the main problem is that the phone wont pick up  network on its own after it drops. Ive had other phones and they all pick it back up after the phone is in signal range again- however this one will not. Although it used to.

Seeing how LTE is almost always weaker than 3G my personal recommendation is to set your signal to 3G as the preferred. 

Settings > More > Mobile networks > Preferred network type then choose WCDMA (preferred) /GSM

If you have no need for data while talking on the phone then give this a try and see if it reconnects to the signal on its own. If it does then your LTE=4G signal is too weak for it to pick it up on its own, and it is not automatically dropping down to 3G as it should.

This has been happening to me for some time. I have needed to re-start the phone 10 times a day.

Yesterday, I took out the SIM card holder and then blew into the empty slot until I could feel the air coming out of the sides of the phone.

Seems to work . Since yesterday, I have not had a problem.
