[HTC One X] Delusphere:
Here is my Log between 2 One X devices I had in my possession for a couple of weeks. After trying 13 phones from starting this thread, 11 In store and 2 that I owned - I can confirm, unofficially, the Hardware is to blame, along with terrible internal build quality, and buggy software.

Log:

1st HTC One X - S/N: HT23 - Made in Taiwan - Wed 11th April -

The screen is clear and white.

Flickering in Recent Apps screen, anything dulled in the background, anything Grey around hex value #808080.

Battery dies within 20-30 mins of casual use.

Battery takes 2-3 hours to charge from near 15% or less.

Signal randomly stops, and comes on and is unpredictable.

2nd HTC One X - S/N: HT23 - Made in Taiwan - Wed 18th April -

The screen is Yellow, like a more warm tone, like the warm setting you get on some HDTVs.

There is no flickering at all.

Colors are not as good.

Battery is lasting MUCH longer, full day casual use, isn't dying within 20-30 mins of use.

Battery is charging MUCH faster, compared to waiting 2-3 hours, from 15% or less.

Signal never randomly stops and restarts.

2nd HTC One X - S/N: HT23 - Made in Taiwan - Update Thu 19th April @ 8:10pm -

The Yellow screen and clear white screen is caused, apparently, because HTC use two different manufacturers to make the screens.

The Yellow screen is made by Sharp, and the clear white one is made by Acer which also has better colors than Sharp's version.

1st HTC One X - S/N: HT23 - Made in Taiwan - Update Fri 20th April @ 2:38am -

Updated to 1.28, made no difference.

1st HTC One X - S/N: HT23 - Made in Taiwan - Update Sat 21st April @ 12:52am -

Screen is constantly flickering now.

2nd HTC One X - S/N: HT23 - Made in Taiwan - Update Sat 21st April @ 1:43am -

Updated to 1.28, running flawlessly. But screen is still Yellow. An Update can't fix that.

2nd HTC One X - S/N: HT23 - Made in Taiwan - Update Sat 21st April @ 5:57am -

When booting, the screen changes colour and goes more Yellow! Everything washes out.

Log End - Sat 27th April

So, I gave up, and sent them both back to Amazon. After this, I tried 11 phones in store (Carphone Wearhouse) for my Brother, until we found a working faultless phone - or so I thought.

Every phone I tried had similar faults, including an internet cut off issue, and a network cut off issue. Some had dead pixels too.

And guess what, the phone my brother got, eventually inherited faults, including, what I call, Phantom Touch Screen Syndrome, where the screen is randomly registering random presses on the screen, rapidly, and causing havoc. It's like Sonic the Hedgehog is using the phone at hyper speed. The screen started to flicker on greys too, the Wifi hardware fault also kicked in and the signal kept dropping too. This all happened about the beginning of August.

I'm glad that after a few months, the hardware and software issues have finally been acknowledged. It's sad that HTC would lie outright about it all. I'm glad we have been proven right though.

You are taking a huge risk buying this phone, and I would recommend against it, and settle for the HTC One S or the Samsung Galaxy S3 if you want a compromise. HTC will play us for stupid pretending they don't know about it, because they have a reputation to keep and don't want it damaged. It's a business game, and many company's do it.

Would really appreciate if you could click Thanks since I'm new to posting here, help me get started. I've been using the forum for more than a year though.
