A new sim card is a good idea.. so is removing the back cover and cleaning off the contacts with a q-tip and some rubbing alcohol. Taking something and SLIGHTLY bending out each of the gold contacts so they make better contact with the case, making sure there is no debris.

Another thing to look into- there is a TON of hacks for cellphone signal that can be done in build.prop.. playing with those settings is probably a good idea.

The last idea- the signal is actually NOT different. The number of bars it shows you is now just more ACCURATE. You still lose signal in ONLY the exact places you would have before.. but now when your phone would show you as having 1 or 2 bars(on gingerbread) right before you lose all signal, on ICS it shows you as having NO bars because you truly have almost lost the signal. It is VERY accurate, now that I am in an area with bad signal.. I have actually flashed gingerbread again and things did NOT get better, there was just fewer bars that weren't as accurate. But I lost signal in the same spots, and would lost 4g in the same exact spots..
[HTC Amaze 4G] tnkrer:
Guys, OP here. This question/workaround is not about getting 4G. I am getting 4G just fine. Its about the phone signal (the bars). My amaze does not get good phone signal in some areas and when I set the network mode to GSM only (2G), phone signal strength and stability increases. and now I want to figure out how I can keep the setting to 4G and get a good phone signal
[HTC Amaze 4G] tnkrer:
Hi SBD, thanks for coming in. I will look into build.prop (ro.ril properties I think) I will also clean any dust inside the phone, may be that will help. The sim card was new when I got my amaze .. but no harm in trying. So I will ask for a new sim card too.

However, in my case, I have a different experience. This is what I did in a weak signal spot.

Have 4G on. I get 0 signal. Can't make a call

go to 2G at the same spot, I get 2-3 bars. I can make a call

I used opensignal app to check signal strength in both cases. with 4G it showed 0. With 2G it showed 42%

Another test. On my route to drop kids off for their day camp, I was on a call (with 4G on) and dropped the call twice (bad reception areas) while going. I switched it to 2G and while coming back did not drop the call.

Before I found this workaround .. people called me and complained that it directly went to voicemail and I never got the call. (no signal). Since I found the workaround, I haven't heard that from anyone.

So I am convinced that there are some real issues in catching the signal with 4G on that get resolved in "2G only" mode. (may be it has to do with the kind of cell towers we have in our area and nothing to do with the phone)

will update if I find more
[HTC Amaze 4G] KnowledgeBroker:
Yea, it should be lines that have ro.ril that youd eant to change.. and fortunately one of those that you can add(it isn't included by default) will do exactly what you need, default to 2g signal when 4g is too weak. I actually need the same thing, in Jacksonville we have great signal.. except in this new place I moved into. It drains my battery by trying to stay with 4g.. but I don't have time before work to find it.

Look for a tthread by "master&slave" titled something like "super build.prop tweaks" in the vibrant forums, I THINK they had that line.. otherwise google around for something like "build.prop signal tweak" as if it isisn't in that thread, there's a really good one on some other forum.

Also, I remember there being some app that requires root that allows you to toggle between GSM preferred and 2g only.. it changes it at system level, and I don't think it was on the play store, I think it was on Xda.

But yea, I understand your dilemma, and until we get an alternative radio to flash(which I don't forsee), that is the kind of workarounds you need. If you find a reasonable solution make sure to post as it will help me too!

[HTC Amaze 4G] BillyD325:
Glad I'm not the only one...

I have had this problem ever since I got my phone in October (right after launch). Updating to ICS didn't help. i've been planning to root and try another ROM, but so far have been skittish as this is my only phone. hasoon, you say it's the SIM card? I am trying the switch to GSM only to see if it makes a difference. My problem is at home - I have terrible service and I live on a mountain with cell phone towers everywhere. My daughter's AT&T and my old AT&T Nokia E71x had excellent service there. I'll let you know if this helps. Maybe a trip to my local t-Mobile store is in order.
[HTC Amaze 4G] soundping:
It's not the sim card. I noticed on google a lot of people have this problem with htc phones. It's just a bad radio. :(
[HTC Amaze 4G] KnowledgeBroker:
We know. If you wanna help read my post number 16 or try some of the links he posted in 17.. we just need a decent workaround.
[HTC Amaze 4G] KnowledgeBroker:
Any results yet? I used to get great signal, but where I live I'm constantly on the cusp of losing all signal.. I get about 16hours of life at home, but when I work eight hours somewhere with good signal, I get about 24 hours of battery.. so you can see this would make a huge difference for me and anyone else in a weak signal area.

None of those posts show the tweak I was talking about so I'm gonna see if I can find the specific one I used to use since I'm off today..

[HTC Amaze 4G] tnkrer:
Hi SBD.. Didn't have time to experiment yet. Google searching did not yield any more information on those properties to definitively tell which one of those will do what we want it to do. So next step, when I have couple of hours is to experiment with one property, see if that helps, if not strike it out and move on to next. I will report whatever doesn't work on this thread also. I will have some time on Sunday to try this out.

One more link with some decent info (doesn't help me on the properties ..)

After I found the work-around and searched, I found that it was found/reported in many places. Figuring out the right search words is more than half the battle :)
[HTC Amaze 4G] tnkrer:
I will update this post with all the different properties as I try them ..

First one to try is ro.ril.hsxpa

I had this at 5, I changed it to 2. No change in behavior

Changed to 1, did not help in any way .. so going back to 5 for this property ..

One down many more to go :(

I noticed that there are a lot of ro.ril properties in the build.prop

So now I removed most of the ro.ril and see how that works out

That did not help either! So now back to trying to figure out which property to muck around with.

One thing I noticed is .. I have 0 call signal ( 0 bars) However, my 4G signal is strong (based on how fast the websites are loaded) (screen capture coming ..)

So 4G signal has two separate components for call and data??
[HTC Amaze 4G] KnowledgeBroker:
Most of the lines included in stock build.prop like the one determines the speed of the connections, so increasing those(I think 8 is the max I've tried for that line) will increase your data speeds. Focus on ril lines that the build.prop doesn't already include, they are harder to find, but if you search for things involving scanning interval you will have better luck. The property we need is not included in the stock build.prop or any rom I've seen, so that should help narrow things down.

I just started a new job so I've been short on time, I will look into it more when I get some free time!
[HTC Amaze 4G] shuvarts:
What if you use wifi calling instead at home? I assumed that will turn off your signal and you can still call through wifi calling. So, shouldn't wifi calling theoretically improve the battery life?
[HTC Amaze 4G] KnowledgeBroker:
It did improve battery life, and for just texts it is fine.. but I have the problem I know some others have reported, a noticeable delay on calls with wifi calling. I connect to wifi whenever possible simply because strong wifi is better for the battery than searching for signal.. but with a 4 second delay(for me) wifi calling is not a solution I can look to.
[HTC Amaze 4G] KnowledgeBroker:
Hey, so I found a tweak for build.prop that should help.. look for this line in build.prop, I don't think it exists in most roms, but it changes the scanning interval for stronger signal. Try adding this:

ro.mot.eri.losalert.delay=1000

Increasing the number increases the number of milliseconds of between scanning.. I am trying 2000 now(should be scanning every 2 seconds). I am pretty sure it is scanning by default almost constantly, but I haven't found what the default number is for android. People seem to get better results with something between 1000-2000

There were a few posts that say it may break wifi tethering, but I just tested and mine works fine.

Of course if you do NOT have signal, that means longer periods before it scans to find signal again.. but this will keep it from trying to find 4g when on 2g constantly, so therefor reduce the drain of weak signal. Edit: and just to clarify, your bars of strength will constantly fluxuate in real time, it searching for NEW signal is what is effected.

The only other option I can think of is finding a quick way to toggle between 2g only and 4g/2g.. if on 2g only it won't search for signal at all unless you lose all signal.

Let me know if it helps you.

Edit: where I am now that has very weak signal, it normally switches between no signal/2g/4g every few seconds.. now it is on 2g(where I actually have bars) all the time, it has hit 4g once for a minute.. but went back to 2g. And I haven't had a total signal loss, which is what seems to happen when it hits 4g and loses it. I have no idea how much battery improvement there might be, but at least I am pretty sure I will drop calls much less.
[HTC Amaze 4G] tbonezx11:
Any idea how this might affect battery life? I'd assume it would cut into it a bit with a more frequent signal scan. I'm giving it a shot. Just added & am rebooting...we'll see how it works. My office is the worst...when I lose signal, it can take a full minute to find it again. I usually toggle WiFi on/off & it finds signal faster...hoping this is a more elegant solution.

Thanks!
[HTC Amaze 4G] KnowledgeBroker:
Stock system scans more often for stronger signal when you hit 2g or lose signal altogether.. so increasing it to 1 or 2 seconds(setting at 1000 or 2000) will force it to stay at 2g or no signal for that long before being allowed to search again. The stock system scans much more than that, so this will increase battery life.

Of course if you can't get 4g at all somewhere set your phone to 2g only. When you go somewhere that has 4g again, switch back. Or find an app to toggle between the two quicker.

Another option that we can look into is getting something like this working: http://xdaforums.com/showthread.php?t=739530

I'm going to work now, but I have the next 2 days off, so I can take a look at how he signed the file and fix it.. but in the meantime anyone else with a similar issue may want to play around with it a bit, there it is.

Edit: I pushed the file to /system/app and installed it, installed/opens fine.. going to test it to see if it is properly switching between 2g/3g screen on/off.
[HTC Amaze 4G] tnkrer:
Thanks SBD for finding that app. I pushed it to system/app and tested it. It sort of worked, but the change over from 2G to 4G and other direction was not happening all the time. Also the manual toggle using the notification plugin simply did not work for me. Worse, my battery started draining really fast. So I removed that app. Now I am thinking that I should find or write a simple toggle that essentially does what we do via menus. Always wanted to do some coding around android .. may be writing this toggle app (and I can start with the app that you have linked to) is a good start.

Now to find a tutorial for how to write android toggle apps ..

On a side note .. I keep flashing other ROMS and keep coming back to energy .. I suppose I like sense .. So when sense 4 ROMs become functional/stable .. I will try those.
[HTC Amaze 4G] tnkrer:
Update:

Haven't written app to toggle 2g/4g yet, might still do it when I learn how to write the apps. (so far installed the environment to create a hello world app :) )

However, I found a good enough solution that has reduced my need for such toggle app. I use HD widgets and when I set 3g or 4g switch, it takes me directly to the menu of setting Network Mode. So that's what I am using until a better app becomes available
[Galaxy S III Themes and Apps] JT-KGY:
Hi Everyone! I'm new to this forum.

I've been using a Galaxy Nexus for a while (unrooted).

Recently, switched to a verizon Galaxy S3. The phone is unrooted and I hope to keep it that way.

One complaint I have with the S3 is the font size of the email inbox listings.

I really love to use more of that screen real estate to display more text like the client on the Nexus.

I read this thread http://xdaforums.com/showthread.php?t=1760741 and few other threads here using

the Search function about alternatives and possible solutions.

I also found this very helpful thread by AndroidFan4

http://xdaforums.com/showthread.php?t=1728308

But the instruction replaces the stock S3 email client and the phone needs to be rooted.

Is it possible for me to install the ICS Nexus email client like an app while keeping the original S3 email client?

Is it possible for me to do above while unrooted?

Any possible downside of doing above?

Thank you all... this is my first post and I hope I did it in the right place.
[Galaxy S III Themes and Apps] danarama:
No it replaces it.

What exactly is it you want? I cant understand how you're describing the issue. Ans what exactly did you want to keep that the google version doesnt have?
[Galaxy S III Themes and Apps] JT-KGY:
Thanks for replying....

In short... I'm hoping to install/run the email client from Nexus/ICS as an installed app (is that possible?)

Maybe even running it off inside the /sdcard folder?

I'm just hoping that by doing that... I won't have to have my S3 rooted and I dont mind keeping the S3's native email client around.
[Galaxy S III Themes and Apps] danarama:
When you try to install it it says its a system app and it will replace. I'm not sure what would happen if you're not rooted. But you could easily swap it if you were rooted.

What is it about rooting that puts you off?
[Galaxy S III Themes and Apps] JT-KGY:
It's a company phone... and technically not my property...

It will replace the system app? It will do that even if the names are different?

So if I renamed the Nexus email app to EmailNexus.apk or something..would it still replace the SecEmail.apk?
[Galaxy S III Themes and Apps] danarama:
You can rename it what you want. The system does not take account of what the apk is actually called.

For example:

SecEmail.apk - Samsung modified email

Email.apk - Android standard email

Both are known to system as "Email 4.0".

Like on a windows computer, you can rename dropbox.exe to sponge.exe but when its installed, windows still knows its dropbox. If you had dropbox installed and tried to install sponge.exe, it would want to modify, repair or remove it as it is already installed.

Hope that helps you clarify.

There are 3rd party email clients in the play store. Maybe they would be worth checking out.
[Galaxy S III Themes and Apps] JT-KGY:
Thank you!

Exactly the answer I'm looking for.... that clarifies my question.

So either 3rd party, wait for update or just root + ICS Email.....

I'll think about it....

Thanks again rootSU!
[Galaxy S III Themes and Apps] gtuansdiamm:
Well you can back up the s3 email app and replace it
[Galaxy S III Themes and Apps] danarama:

My Transformer has the same issues as everyone else; it's extremely laggy, apps crash, etc. But I also have this thing where every once in a while, if I click on something, my screen will go white with a line at the bottom and freeze. I have to restart the tablet to get it working again. I read through a lot of different threads and couldn't find anything. Is anyone else experiencing this?
[Asus Transformer TF700] Kimusubi:
I can't find any causes/solutions online. Any ideas?

I am having the same issue. Started last night. Froze up first then a bit later went to white screen then rebooted. Today it froze up again...no white screen this time but could not access settings...the icon for settings was there but nothing else. Happen after reboot again...shut it down after that till now. Had been working fine. UPDATE is needed badly...I also have the Acer a700, that has been great so far...much better than this one.

Happened once to me too, i rebooted, and it has not happened since.

Haven't had the white screen return yet but I have had a recurring issue with freezing. Tablet was working last night when I put it down...this morning there was no internet connection. Went to settings to turn on wifi and it froze, just like before, only the settings logo and the word settings were visible. Received a message about the program not responding, my options were to close down or wait for program. When I got the white screen before it happened just as described above.

Here is the thing, installed the 9.4.5.26 20120720 firmware update earlier last night...I was hoping that was the fix for this issue but no such luck.

Worst purchase ever!

I really like Andoid, I currently have a Galaxy S3 phone and I don't have any problems. I really wanted an Android tablet and with the higher resolution the Infinity seemed like the one to get. I have had it for a month and I think this purchase is one of the worst I ever made. With the keyboard and accessories I have around $1000 invested in a tablet that only works part time. It crashes at least once a day while doing different tasks. Just now it was just sitting there on the locked screen and the screen went to all white. Holding the power button didn't do any good and I had to use the reset button. I feel like I wasted my money and I don't know if I should avoid Asus products or if Android tablets suck, the problem might even be with Jelly Bean. I don't like Apple at all but I really wish I had bought an iPad.
[Asus Transformer TF700] AM Radio:
this has happened to me three times in the last day, and each time while i tried to play an MP3 and read a Kobo book at the same time. (don't get me started on why a $500 tablet can't play music and display text AT THE SAME TIME. what the hell).

i'd start the track, load up kobo, and BOOM: white screen. i think i know why: all my music was in internal storage. for the hell of it, i moved all my tunes to the microSD card. and no more white screen, i can read and listen to tunes at the same time.

go figure.
[Asus Transformer TF700] spinaldex:
I've been having this happen a lot. Essentially, I have two things happen:

1. In some app (Firefox, Redfin (we're house hunting), etc) and click something. Tablet freezes. Click something again, and it resets. The next thing you see is the black screen w/ Asus logo.

2. Same as above, but first you get a full white screen for ~10 seconds. THEN it reboots and you see the black screen w/ Asus logo.

It happens at least once an hour under heavy use of the tablet (lots of app switching, browsing the web, etc).

I have:

1. Cold booted.

2. Upgraded to JB.

3. After upgrading to JB, I reset cache and everything *multiple* times before installing all new apps.

Is this a known issue, or are the few people complaining about it just F'd?

I have this issue under Jelly Bean, but never had it happen under ICS. If you are in the same boat, an exchange will likely not help. Your best bet is either to put on a different firmware, or get a different unit all together (ie, not Asus).
[Asus Transformer TF700] Vertron:
The problem is that Asus decided to use a cheap nand chip that has slow i/o speeds which causes the lag. It's not a problem with android. Have a look at a note 10.1 if you want to see a lag free tablet.

White screen is a known issue with JB, it's not hardware issue. We just have to wait for another update from Asus.
