My htc one fell from 3ft. and it hit its corners 3 times before finally lying face down on the ground. It was in a TPU case and doesn't have any cosmetic damage at all. However once I picked it up the home button wasn't working properly for 15 seconds, but it worked after that.
My lock screen has become kinda slow, when I put the wrong pattern it lags a bit and after 2-3 seconds it says sorry try again. This never happened before. Is it possible that it became slow after falling down? And is there any way i can verify that. Like with antutu, benchmark scores?

Sorry for the noob language

Try rebooting the phone, this may help.

Of course i tried that. Didn't work.

you are just a bit paranoid due to the accident with the phone... it happens.

the phone wont become slower from a fall. had the memory, processor or any other internal component become damaged you would be finding error messages, unstable usage, random reboots, and what not.

try running an app like clean master to clean old cache and remove apps from the memory, and reboot.


if after that you are still convinced your phone is not operating properly perform a factory reset.

if you are still unhappy with the performance of your phone after that, you should consider sending it to htc to have it fixed. i insist, however, that if you are not experiencing any other problems but a slight lag the issue lies with software.

finally, check that the camera is working well. it should be your main concern after a fall.

First off I'm glad you had a case protecting your phone, probably saved it. Secondly, I don't see how a fall could effect the software. Maybe the lag was always there but has been exaggerated in your mind due to the drop?

I performed a factory reset, and the lock screen lag was gone. But then I updated the phone to 4.3 and now its kinda slower. the stock music app lags a lott.

I compared it to my brothers one, and his did not lag at all. Dont know whats happened. Im scared that if i send it for repair, they might scratch it and all

sometimes when updating to a new OS the system might become a bit slower at first until its done indexing everything. give it a day before jumping to conclusions on 4.3.

at least now you can rest assured your phone has not been damaged from the fall.

Comparing a lag free phone to your phone isn't really an appropriate test. Yours could have been laggy due to an installed app that your brothers didn't have?

[androidfan72]

Maybe, but do you think visiting a particular website could make it lag? I went to some (u know) sites and i got redirected to some unknown website.

I couldn't say, I don't know if a virus of a site can effect a phone like it would a computer. Try avast from the play store, scan your phone and see.

virus these days are more concerned about stealing information from you than crippling your system's performance.

so no, visiting a particular website does not make your phone lag.

[androidfan72]

ok but just in case if i want to verify the performance, would benchmarks be the way? like comparing my score with others?

Let me google that for you

I had this issue twice. It happened only after I change the battery myself. Had no similar issue during the first two years of use. But since I changed the battery (disassembled the phone completely) ... twice ... a fall made it slow. After the first time, I just left the phone switched off for 2h, and it worked fine again the next day. After the second time, I had to disassemble the phone completely.

My experience is the proof the phone can become slow for a hardware reason; no software involved here: became slow on the minute it fell; became smooth again after waiting some time, or messing ribbons; did not install or remove any soft. It can be many things: a chip is broken, is does not touch correctly a heat sink; a ribbon is damaged and does not conduct properly and one chip has undervoltage; a pin has a bad contact in one connector; energy of a shock could justify for any component to move just by 0.01mm and have a poor connection.

The problem is related to video part of phone. CPU performances are not affected for me; only graphics are affected: video acceleration, 3D rendering, and refresh rate of screen. So the issue could be video RAM, GPU, or I2C bus to LCD, or some clock. Clocks are very sensible to shocks, and are know (by experts) to be the most sensible component; the quartz is the first component that may break during a fall; followed by bulky ceramic capacitors (they get internal micro cracks if PCB bends a bit: the ceramic is very hard and will break before the flexibility of solder will compensate the bend - any crack will change the capa value).
