[Q] Need cell phone tech! - Thunderbolt Q&A, Help & Troubleshooting

Alright so I just bought a replacement digitizer for this tbolt I picked up a few days ago, replaced the screen. Everything went fine at first, responded quickly, etc. As of last night, there is a now a vertical line where the screen is unresponsive. It lines right up with the Z and W keys, and i don't want to have to keep putting the phone in landscape just to get it to work. What should I do? order another digitizer? or is it maybe a connecting pin on the motherboard??

Personally I'd take it all back apart and check everything again prior to buying another new digitizer. Might take a few minutes but if it's just something easy it's worth it IMO.

Id contact who you bought it from and request an exchange if possible. Where did you buy it?

[Q] screen pressing itself automatically?!?!

hey guys.
I gifted my mom my Evo 3D a bit over a month ago. It was in perfect condition after a year of use. she says she hasn't sat on it. no screen cracks, no indications of any physical abuse.
we first thought it was the keyboard. and she had been telling me of so many issues she was having. so I updated her to freeza's 5.5 rom, sense 3.6 version (how come I didn't see any JB roms?! I've been on JB for a while...).
same thing kept happening. i started looking into it. turned on the pointer touches thing in developer options...turns out, the screen keeps pressing itself exactly in the middle horizontally, and about 85% of the way down vertically.
sometimes it keeps pressing so when it's a keyboard up, it presses the letter v continuously. but it presses everywhere. so it makes phone calls, selects things in market, selects in root explorer, etc. sometimes it gets "stuck" on pressing down, so nothing else works. you can see the pointer is stuck as if it was being pressed.
in TWRP i couldn't select the last item in the list (the one i was trying to flash!) but all other "lines" could be selected.
there are other issues (since we're on MetroPCS) but I can figure that out after the screen issue. since it happens across roms and in TWRP, I'm fairly confident this is not a software issue?
what can I do? is replacing the digitizer a sound idea? how much would that run me? how difficult is it to do? i'm trying to wonder if it's just a better idea for her to get a new phone....
any help with this is highly welcome. this is WEIRD!
id say the digitalizer. around 80,-, google. since you flashed another rom, it's highly unlikely its software..
Mine also does that. Rarely though. I thought it was because of protective film. Turning screen off and on fixes this.
I also have the same problem when typing with wet fingers.

Your digitizers are dying
My advice is to keep a stuck ruu in your phone's sdcard in case of scenerios like this one because we all know that sprint techs may not even touch the phone if they discover your rooted and s-off. So, getting back on stock with "locked" bootloader is your next move. Thankfully that procedure doesn't involve using the touchscreen.
Take off any screen protectors, and make sure you are using the default HTC lock screen - HTC hard coded the calibration for the screen into the lock screen. If still problems, then yeah, you need the digitiEr

that was my first thought. to remove the old screen protector. but no, it's definitely messed up
no problems. the same store I bought that phone from and my other Evo 3D and the two Galaxy S3s from does repairs and they replace the lcd and the digitizer for $80. i've dealt with them for years now so I trust them.

Uhm... the digitizer for our phone costs about $10 or so... and from what you said your LCD is just fine... so I really wouldn't trust a store that's offering a $10 fix for $80... so bottom line just check if they can just replace the digitizer as it's the exact same procedure...
well looking online it looked like the whole thing was $60-100. on this thread i was told about $80.
that's not the issue though, problem is putting it together. I watched the video of the step by step, and there's way too many ways I can mess it up, and then my mom is out of a phone, instead of spending $80 for guaranteed work.
On my iphone I had a dead spot in the middle where you could see the digitizer was discolored if you looked at it at an angle.
I had a screen protector(or clear plastic, etc) placed between the LCD glass and the digitizer and it fixed the problem.
I guess it kept even pressure between the glass and the digitizer.
Worth a try if you don't mind experimenting but YMMV.
Don't risk it if you aren't confident though... I did it to my iphone because I hated it, lol.
Good luck.
well this is weird.
i'm supposed to take the phone to be repaired tomorrow morning (Thursday) so I decided to beforehand update everything on her phone.
I did a superwipe, installed the latest TWRP, flashed the ICS firmware, including Hboot 1.58 (i'm still S-OFF, thank goodness), flashed Cool ICS 12a...
and the phone is behaving like new. no screen pressing, no difficulty typing, over the last two hours of setting it up for my mom...it's as if it was brand new.
so now i'm wondering if somehow it got fixed and we can save ourselves the expense, or if this is a temporary fix and it'll go back to messing up...
I'm GSM, rom is without sense. But sense rom had the same issue.
Is it possible to calibrate screen without sense?

Touch screen problem

Hello everyone!
My sister accidentally detached the screen of my phone because she was taking it from me. After that, we take it to the repair center (a store only in a mall) and they said that the screen is unavailable for now. The repairman suggested to take out the battery from the phone until the screen is available to order. One day I tried to turn on the phone with its battery inserted to see if it still works without the screen, I thought of the phone was still working fine because it still vibrates when you powered it on and I immediately removed the battery after doing the testing. It almost took 2-3 weeks until the phone was repaired (the screen replacement has no warranty). Then we got home and played with my phone. Suddenly, the touch screen doesn't work, I have waited for a few second then it works again. It keeps happening like that and there are times that the screen completely doesn't respond to my touches until I reboot my phone. The apps that I were using that time are responding well only the touchscreen does not responds well.
I am using a custom ROM while my phone is being repaired.
So here's my question:
Will touchscreen problem exist or occur if you didn't turn it on or use it (powered off) for a few weeks?
The phone that I'm using is Xperia Mini Pro SK17I. I have also tried other custom ROMS like CM10 and CM10.1 but it just makes my touchscreen worse.

Hey there.
What a coincidence, I just went through this kind of problem. Sorry to tell you this, but the screen assembly you bought is defective and there's little you can do about it, save for flashing back to stock and hoping for the best.
I ruined my xmp's screen and had to get a replacement part. I was in a rush so I bought a new display from the first store I came across with. Result: the touch digitizer was deffective, pretty much useless on CM10.1. It worked for a few minutes, but then it stopped responding until the next reboot. Touch response was sloppy, and two-finger gestures were all messed up.
Flashing back to stock ICS helped a bit, but it was far from ideal. I had to cope with it until it finally drove me crazy and I threw it to the ground. The glass shattered, many pieces flew off from the phone. Saved enough money for another screen and I'm just fine with it. No problems even after doing exactly what you described.
Word of advice: get a new screen assembly, and flash back to stock while you're at it.
Would you tell us how much the good assembly costs? Just for reference.

I usually buy these from a local store for about $40. Check the display and touch digitizer quality before buying when possible. If you plan on buying one online, don't go for the cheapest alternative you can find, you could end up regretting it.
I'd recommend buying from "formymobile.co.uk"
Some people might not know this, but the display and touch glass on the xmp cannot be separated. This is good and bad at the same time.

I am now dissappointed with myself because I didn't take my phone for repair to the store where I bought my phone. I have already brought my phone there before because of screen replacement too and they replace it with a good and functional one then that store move its location that was far away from us and that takes us to bring the phone in the nearest mall here in our place.
We found a store inside the mall, they fix it and TA-DAAAAA, a phone with a defective screen. And yes, the gestures are not working properly. I really love this phone but I can't take it anymore for another repair.
I am planning to buy a new phone but not a Sony Ericsson phone. I will buy a local branded phone [Cherry Mobile (Android phone) - search it on Google to see it] here in our country (Philippines). It is much cheaper but has a good quality. I am just a student so it will took me a long time to buy a new phone.
Unless my parents decides the buy me a phone because they also use my phone for playing.

The 1st screen replacement that happened to my phone (it was the good one) costs me $77 (based on Philippine Peso to US Dollar)
While the 2nd replacement which is the bad one costs me $55

Phone bump causing power off?

Well my awesome sauce with the note 2 seems to be doing downhill... I LOVE my phone... then all of a sudden yesterday I had it sitting on the arm rest of my recliner.... I accidentally knocked it off on to the hardwood floor and it must have hit just right as it cracked the screen. The phone still functioned fine, but the screen was cracked. I took it to a local cell phone repair shop to have the screen replaced. When they put it back together it wouldn't boot... well then after replacing a button, it booted and they thought that was it. Well after it booted I made a call, and as I set the phone down, I noticed it turned off. So after a couple of more boots and confirmations that tapping it at the top of the device did this, I got a charger. Well with the charger plugged in it does the same thing, which tells me it's not a battery connection as google searching would lead me to believe. Please tell me someone knows something to try and fix this? Should I just cut my losses and buy a used device? I see beans has his on swappa and it's making me consider coming up with the money to do that. Thanks for any input/advice!!!!

Damn! They're supposed to test it out after they replace the screen and give it back to you. These screen replacements are very sensitive and you have to really use caution when messing with them. I've never heard of this but do you have a case on it or around it at the moment? sorry man. Have you discovered anything else?
Well after he spent some time with my phone last night, he said he thinks he found a loose cable. I picked it up today and it hasn't shut off yet. The screen looks beautiful by the way. Back to playing around with Trents Rom!

Glad the store solved that out. I've had a similar thing if I tap my phone on a table around the camera area it just shuts off as well. Only solution I've found is using the massive case from the 9300mah zero Lemon battery. Adds a sought bit of bulk

I droped my DNA about 1 month ago and the screen cracked, luckily the digitizer was fine but the glass was cracked bad. Then a week later I guess I was to "rough" with my DNA and I screwed up the digitizer. Al I could see was a black screen with some green and purple lines going on it. So I needed to get it replaced, it would cost me around $150. Everything was working, even the screen, I could still feel the vibrations of me trying to put in my passcode, in other words, it could still recognize me puting in touch inputs but I could couldn't see what I was touching. I put in my head phones to listen to music, and it was fine, the sound was clear and everything. 2 weeks later I go to the repair shop to get it fixed, they put on a new screen and it looks brand new. I get home and I notice the side of the screen is messed up because when I try and press the q button on the keyboard it types the lettet w. So as hard as I try to type the letter q, it won't work. Sadly, I didn't test out my earpiece or the headphone jack. Now I take it back and they order a new LCD and digitizer. I come back in a couple of days so they can put it on the screen works fine. The next day I try to call one of my friends but I notice there was a problem. When I call the screen goes as normal, but when I take the phone away from my head, the screen doesn't come back on. No matter how hard I tried to get it back on, it would get back on. Worst, the earpiece didn't work. I couldn't hear anyone in a call, they could here me but I couldn't here them. I take it back to the repair place, they order like 10 earpieces but it didn't fix the issue. Now they are saying that the problem is my motherboard. So at this point, the only things that don't work are the proximity sensor, the camera because I get an error (cannot connect to camera error), the earpiece, and the headphone jack because its all staticy when I try to watch youtube videos. Yes I have tried many many headphones but the problem keeps persisting. I forgot to mention that my doubletap2wake doesn't work or my sweep2wake. A couple of days later the guy who owns the shop says the problem is the motherboard. I try to get my money back but I had no luck. What do guys have to say? I came in for one problem to get fixed, then I get another. Worst of all my phone just shuts off at like 50%. I can't restart it or anything, I have to connect it to a charger in order to turn it on? What do you guys have to say? They said that when you open up the phone, the pins that holding things in place break off and people get these issues. Sorry for this being so long.

Sounds like they messed it up bad when they put it back together. What repair service did you use. It might not even be worth bothering with the phone anymore it sounds like they messed it up when they were in there fixing it. Make them fix the entire thing or make them get you a new phone. Judging by how many problems are present you may as well just get a new phone.
Please press the thanks button if I have helped you in anyway.

I do agree it is time to move on to a new phone. Although as much as we want to MAKE THEM get us a new phone because they missed it more then it was already messed up. Not going to happen. I have the HTC one max and I would recommend that and or you could go after the latest HTC device the famous M8

Nope, warranty expired a couple of months ago. The weird thing is, my friend stepped on my phone at school, then when I turned it over, it wasn't cracked and what is more bazzar, everything was working fine, the dt2w, the s2w, the earpiece, the proximity sensor, the camera. Then an hour later, those things were back to not working again.

Here is what I would do in this situation. Sell this phone as a phone that is not working and can be used for parts on eBay. Then with whatever money you can get try and buy a new phone.

[Q] Broken digitizer on my rooted S4

So, the other day my phone fell about four 3.5 feet down on its back. I pick it up and find a small crack on the screen, oops, but I can live with that... I hit the home button and my screen flickers... I had my girlfriend call me and the phone reacted normal with the exception of the screen being broken, I was even able to swipe and answer the call and talk to her. I figure out that my digitizer was broken. I have insurance on my phone however my phone is rooted on MDK. "Why not upgrade?" you may ask, well I have been contract free since May of 13 and bought this phone outright to keep my unlimited data. So, I purchased a digitizer replacement on Amazon and during the process I broke one of the antenna (the one on the left side when looking at the exposed back) I didn't think much of it as I can order that part as well. Once I have the the new digitizer in place I go ahead and put the phone back together. Well, when I power on my phone the screen still doesn't turn on. AHHHH, I'm assuming my only option is to install the original broken screen and attempt to go through Verizon to replace my phone. I really don't know what else I can do as I spent $200 to buy the new screen/digitizer and that didn't work. Please let me know if I have other options.
