Cannot Connect to LTE or 4G after Nougat Update

Xander0103 — Mon, 19 Jun 2017 06:59:52 GMT

I have recently updated my Sony Xperia XA Ultra Dual Sim to Android 7.0 Nougat. I have noticed that I am unable to connect to LTE or even 4G. I made sure that I am on a 4G/LTE site and my Sim is 4G/LTE compatible. Can you help me fix this?

@Xin0103

Go to Settings -> More -> Mobile networks -> Preferred network type -> set to "LTE (preferred)/WCDMA/GSM"

If it's already set to this option, set to a different option and then back to LTE option.

I have the same problem. SONY please give a solution to this.

Before Nougat, Im playing online with 2 bars of LTE and im not having any problems with XPERIA XA ULTRA.

After upgrading to Nougat, I changed to 3G because I cant be contact in LTE, but switching back to LTE/4G, it cant be selected anymore, I mean its there but it doesnt switch to 4G.

Does SONY even read this?

Transfer your sim to the other sim slat and refresh your phone. Try to select LTE.

Same problem for me. I have tried changing the settings back and forth in

Settings -> More -> Mobile networks -> Preferred network type ->

but it never connects to LTE even if I have selected LTE as preferred.

I have also done a factory reset, but problem remains. The problem is serious since at my home LTE is the only available network in the air, i.e. I can not call and no one can call me when I'm at home.... I'm, not very impressed...

Correction: It seems my phone can connect to LTE, but only if the signal strength is very strong. When I was connected to LTE the signal strength was -58dBm (reported from About phone ->Status ->SIM status). Now I'm at another location and its now connected to HSPA at -86dBm. My other (working phone) is connected to LTE at -101dBm. I have tried to manually force my bad Xperia XA with Nougat to connect to a LTE network by using the Settings -> More-> Mobile Networks -> Network operators, but it returns "Could not connect to network". So, something bad seems to happen that causes LTE to be unavailable most of the time.

Network signal and no LTE

Hi Guys,

So i just updated my XA Ultra to 7.0

Prior to that i was getting consistent LTE for my data. Now, im not getting LTE anymore just 3g to 4g the most and whenever my data is off im seeing an X at my network signal strength at the top but when i turn it on it goes to only 4g.

@Nonotigas

It's the same, LTE is commonly referred to as 4G, and the "x" symbol is added in Android 7 for more visual clarification that you have your data turned off (or not available in that area).
