Extremely slow data connection (3G) - Galaxy Note 10.1 Q&A, Help & Troubleshooting

I tested the same SIM Card in iPhone 5s, and the download speed was up to 4.2mb, with this android it never exceeds 0.02mb!
I'm on Android 4.4.2 Original firmware!
The network signal is full on H/H+
Could it be a hardware issue? I opened my tablet a couple of times before because the screen cable was moved, so I returned it back and everything should be fine, I did not touch any other hardware component except that screen cable!

Sprint TP uses 200-400mah w/ data conn, fast drain, defective?

I have a sprint touch pro, it was fine for the first day or so including active sync always connected.
Then I noticed it would get really warm and the battery was draining very fast, long story short but on a hard reset with only CMP battery monitor installed (which was not installed when the problem first presented itself) the unit uses between 0-100 mah normally but if I have activesync on always connected or even no active sync profile but manually enable the data connection it goes to 200-400 (average around 300 mah) causing it to heat up, super fast battery drain, etc.
One thing I noticed is that it is flipping between EVDO and 1x a lot too I am not sure if this is the cause?
I have several other phones (mougl, 6700 etc) all which would stay on EVDO without a problem here. Is it a defective unit?
Also to note my battery can train from about 100% to dead in a few hours when the data connection is active, vs day+ without.
I also am having a similar problem as the thread http://forum.xda-developers.com/showthread.php?p=2851168
where basically while in a strong evdo area it will rarely connect over evdo and if it does it generally will break the connection within a few minutes and default back to 1x. I think this may be the cause but it still doesn't explain why this is happening.
Mine seems to be having the same sort of issues, my battery, on average is only lasting me about 6-8 hours, I keep bluetooth and wifi turned off. I just got the phone less than a week ago, so it is seeing abnormally heavy use, but I'm really trying to make it last me a day and this isn't looking good so far.
Keeping background programs closed (except glight and gyrator)
Signal for this area is strong, 3g everywhere. I used to be on Helio (using Sprint's network), and my 3g signal never dropped. This phone, when sending a text message, the box switches to 1x, the text sends, then it goes back to Ev. It's the same for making calls. I'm not "dropping" 3g I guess, it's just switching off to make a cell transmission. Browsing sites or using data keeps it connected to 3g.
ROM version: 1.03.651.3
Radio version: 1.03.15F
Now, you think us Sprint Touch Pro users will possibly see a new ROM and Radio soon? I want to try reflashing the ROM, but don't know where to get another stock Sprint one, and I'm positive a GSM radio won't work.
If only the touch pro had 1/3 the following the Diamond seems to :/
Yea I don't think that its due to any programs, at this point I run a hard reset with nothing loaded but the battery monitor and no wifi/bt. As for sprint roms nuechem will be releasing a new rom tonight (see is blog at nuerom.com ) you can flash over.
I think the problem is related to the network however as in 3 different locations now as soon as I go to use a very good strength evdo signal it will drop to 1x for an unknown reason.

[Q] Dropped Tablet - Weak Data Signal

I dropped my Nexus 7 2012 3G and it cracked and stopped responding o touch. I sent it to Squaretrade for repair. After I got it back, I upgraded from Android 4.4.3 to 4.4.4 and I reinstalled my apps. Then I noticed that my mobile network stopped working. It had a weak signal and orange bars instead of white. I could not transfer any data. I reset to factory settings, which allowed the bars to go white and I could transfer data. But I am still getting a weak signal at my house. The signal strength also randomly increases and decreases without moving the tablet. WiFi is less affected, if at all.
Is it possible that in dropping the tablet, not only the screen cracked, but the wireless radio became damaged in such a way that it still works, but does not get as strong of a signal as before? Or do you think this was caused by the (minor) android update?
Thank you
more likely you have to check the antenna

3G stopped working - 2G/4G still work

At some point in time - I can't tell exactly when - after replacing the earpiece speaker of my N5 and updating to the latest Lineage OS version 3G connectivity stopped working.
4G works fine, but if there's no 4G reception or the phone is forced into 3G mode using the settings it drops down all the way to 2G, although other phones on the same network have flawless 3G reception.
I have reflashed the radio and both the newest and oldest factory images available from Google and also tried cleaning the contact surfaces of the antennas in the back cover and I've also bent up the contact springs a little to ensure more contact pressure, but nothing has helped.
Since 4G coverage is far from 100% in my area this effectively limits the phone to 2G most of the time which makes it pretty useless.
Does anyone have an idea what could cause this problem?
Thanks
Open the smartphone again, check connection on both ends of black and grey antenna cable.

Click to expand...
Click to collapse
The black cable's connector on the upper, larger board was loose - most likely due to it being so close to the edge of the phone and me not paying attention when prying the back cover open.
I reconnected it and now 3G works again :victory:
Thank you

Weird issues with my phone after Android 8.0 update

So, to start... My phone is 100% stock, no aftermarket anything or custom anything. After the most recent update to the OS a week or so ago, I'm noticing weird stuff, see below. Anyone have any suggestions? No changes were made to the phone, no weird apps installed, etc.
- Battery drains significantly faster. At 85% it's saying I have 12 hours of battery life.
- Wifi drops outside, despite being only 15 feet from my router. This never happened before.
- Phone will not consistently connect to my Sprint Airave (mini cell tower, Google it). Generally will have one bar of LTE rather than full bars of 3G while on wifi.
Backup everything and reset the phone. Start from scratch. Latest CRC builds are better than 1st CRAP build.
Feedback later.
Good luck
Haven't done the reset yet, but I think the issue with the Sprint repeater is that the Sprint device only runs on 3G, which is fine since at home I'm on wifi. The phone seems to want to connect to the one bar of LTE that I have rather than that. Is there a way to force it to only look for 3G connections instead of LTE? Under the Connections > Mobile Networks section of the settings menu, I don't see it. I recall seeing it there before on this device and other devices.

[HELP][F8332] cellular won't work right after Sony returned my phone

So I went to Sony to get my battery replaced. Sony wanted to replace my screen and motherboard so I decide not to go forward with it. Sony literally returned my phone with my display out and headphone jack issues. I went back and they "fixed" my display but with even more issues. But that all issues aside ever since I got my device back I am having issues with connectivity on my phone. Their service center claims they need to change the board to solve issues which didn't exist before I submitted my phone and they want me to pay for it.
Here's what's happening if I'm on LTE it will sometimes work in bursts but otherwise won't work at all. I have the LTE sign though. Data works more or less fine on HSPA+ if I force WCDMA in settings but sometimes the phone looses signal completely. I've tried replacing my sim, using my secondary sim (Jio, which being a 4G only network is completely unusable on this phone). I've tried flashing my phone with latest india ftf but that didn't change a thing. My Bluetooth range has also shortened significantly.
