Signal strength seems low

Compared to my Note 2 the Note5 seems worse at picking up the Mobile Signal. I have 3G in some places that were 4G, and dropouts in places that were 1x.

This is a Verizon Note5, and so was my Note 2.

Any thoughts? Anything I can do to increase strength?

Thanks.

Signal gps XPERIA MINI PRO

Hello guys, I'm looking to buy a mini xperia pro ( SK17 ) , I'm just in doubt the GPS signal quality can tell me the GPS receiver sensitivity of this model?

Weak (no bar) 3G signal after back from 2G

Anyone with Android 6.0 experience this issue?

So, when the phone enters an area with weak 3G signal, it will go to 2G (GPRS).

This is normal behavior.

Then, when the phone enters an area with strong 3G signal, it will go back to 3G.

This is also normal behavior.

Except, the restored 3G connection is weak. The icon shows with "no signal bar". It is connected to 3G though.

And it will stay like this until I recycle the connection by going to airplane mode and turn-off airplane mode.

My device is Nexus 6, international model. I installed Android 6.0 by flashing the image.

It is not rooted though and it doesn't have much apps.

And yes, I can reproduce this issue every time, as I know exactly the weak 3G area in our building.

Thanks.

force phone to switch to gsm when lte signal is weak?

as the title suggests is there anyway this is possible? i have the network mode set to lte/wcdma/gsm auto connect but the issue is that i live in an area with low lte coverage and the phone will not switch to gsm mode even when the lte signal is close to none which causes sms not to be delivered and i don't recieve phone calls and it causes a huge battery drain on idle when i go to sleep and wake up with the phone even off sometimes..the issue is gone when i switch to gsm only but it is a pain to constantly go back and forth between switching networks any suggestions?

4G LTE & signal bars disappear about 30 seconds after powering on. What's wrong?

So I bought a Verizon Note 4 (Verizon sim from previous owner installed) and a Gear S from a person off craigslist for 0 total. I have not activated Verizon service yet, only using on WiFi for right now. The phone has been updated to the latest BOG5 firmware from Verizon, so looks like no root for me as well :(... Anyways...

...Is it normal for the phone to show 4G and a signal for about 30 seconds after powering on, then have no signal or LTE? Again, I have not activated the phone on Verizon yet, so keep that in mind.

I have checked the APN, and it seems I can't change or edit the Verizon APN. It is greyed out. It also seems it's incorrect. I'm wondering if this is why I get no signal at all.

Anybody have any ideas? I tried putting my metro PCS sim in it as well, and same result, no signal or LTE icon. Even added the correct APN for metro PCS and still nothing.

I also have a Verizon Samsung S6 Edge Plus that is not activated yet either, with a Verizon sim installed and it shows 4G and signal. Also, I can put my metro PCS in the Edge Plus and it works perfectly, without changing or doing anything.

Anyone have any idea as to why the Note 4 isn't working?
