Nexus 4 stuck on pasword screen with lolipop!

Hello every body!

I did install lollipop when the update prompt on the phone and since that time, I had some problems.

My battery drain really fast. and the some keys on the keyboard doesn't work any more. Maybe because I was using swift keyboard and uninstall it after lollipop have been install...

Now my phone is encrypted and last time I turn off and on the phone, when it ask for the first password, the number 3 on the keyboard doesn't work any more.

I tried to restart the phone on recovery mode and the only thing I have on the screen is No command!!

Please help!!

Welcome to Android Central! Have you tried booting into Recovery and wiping the cache partition using the following steps? https://support.t-mobile.com/docs/DOC-5994

Hello B.Diddy!

Thanks a lot for the reply!

I did try the wiping the cache partition with success.

But after that when I reboot my phone, it ask again for the first password, because my phone is encrypted, and the number 3 on the keyboard doesn't work.

Thanks!

It might be an issue with your screen/digitizer, then. Perhaps that one area where the 3 is has become faulty.

Well I did a wipe data factory reset!!!!

God dam it I've lost everything!!

Damn me I should have done backups before installing lolipop!

At lest I can use the phone again!

So even with a wipe data and a factory reset, the keyboard propblem haven't been resolve.

With the phone on vertical, The letter e and c doesn't work. But it work when the phone is on horizontal.

I've tried with the swiftkey keyboard and still the same problem.

So is it always the same absolute location on the screen that isn't registering? In other words, are the screen locations where the "e" and "c" are on the keyboard with the phone in portrait also unresponsive when in landscape? If so, then you have a problem with the digitizer. It would likely need to be replaced.

Good to ear from you B.Diddy!

Only unresponsive when in portrait.

Thanks!

Try using Screen Touch Test to see if there are any parts of the screen that aren't responding to touch.

 

[neokona]

Well there is some parts that aren't responding!!

 

[B. Diddy]

So are you confirming that there's a physical problem with the screen/digitizer? Because I'm just trying to differentiate between a physical screen problem and a software problem.

 

[neokona]

You bet B.Diddy!

I just find it strange! It was working alright and the problems started right after lolipop have been installed...

 

[neokona]

Thanks very much for you help!!!

I wonder if the screen problem actually existed before Lollipop, and perhaps the update to the Google Keyboard changed the position of the letters slightly so that those two are now in problem zones.
