LCD caller ID screen consistently fails in less than two years
356625
Based on two purchases of this phone model, I strongly recommend to avoid. Both LCD caller ID screens began failing in less than two years. The warranty is only 12 months. No more AT&T phones for us.

Junk! touch screen stopped working after 1 year. Google C2665dnf touch screen not working and you will see tons of the same problems.

Very poor visual screen and caller ID. Sound on message recorder is also very poor.

I bought 3 of these and feel that the large digits, magnetized back, stand and rear eye hook are great design features.

2 of the 3 have since malfunctioned in the past year I've owned them. The first stopped issuing beeps after about 6 months of use so I could not be alerted whenever a countdown ended. The second unit's display just blanked out after 8 months of use. The third one is still going strong.

So while it's a great little package, I'm afraid I can't recommend this timer because of its reliability problems.

Bought this unit to replace an identical unit owned for less than one year. It has many nice features, particularly the ability to dim or shut off the display entirely if you prefer a dark room while sleeping. USB port for charging devices at bedside is helpful. Projection works well, and dual alarm settings are useful. The prior unit worked well for about ten months, then gave out a loud spontaneous beep one evening and totally stopped working. Based on this lack of durability I would recommend getting the extended service plan to replace the unit when its many IC chips fry and it gives up the ghost. Too bad Sony seems unable to produce a high feature basic electronic device that lasts for a few years.

Caller id stopped working October 2017. I Signed up for OBiEXTRAs December 2017 and it worked right away. They are an underhanded company for not informing customers they would be making this change. I could have make appropriate arrangements for a replacement but was stuck with no caller id for 2 months trying to troubleshoot the problem on my end wasting valuable time and money. They don't offer technical support without a $10/ year subscription. I mean they won't respond to an email or phone call without being paid. Turns out it was Obihai/ Obitalk changing what was sold as having free caller id. Just a heads up.

After 2 years there are 3 vertical white lines on LH side of screen. Poor Samsung quality

I bought this last month. A few days later the LCD screen won't come on. Sometime is comes on and sometime it doesn't. WTF?

Worked for a few months, and then started failing (cross-hatched lines on the display).

We have had the same problems other reviewers reported.  The caller ID stopped working first after about 6 months.  We were unplugging to reset it several times a day.  Then even answering the phone became hit and miss.  The one good thing is that the manufacturer replaced it with no hassle.  So far it has been another 8 months and the caller ID has only gone out 3-4 times in the past couple months.  But the volume is not good (I'm constantly asking callers to repeat themselves) and it clicks all the time which is very annoying.  We have just replaced it with a phone that got great reviews.  I am hoping it works much better than this one.

We had this unit professionally installed with a 3 year in home warranty from the installer.  Six months after the warranty period ended the touchscreen stopped working at all.  At first I thought it might be "locked" which is a feature, but spent the better part of a Saturday afternoon trying to unlock it to no avail.

I'm loath to buy another unit to replace it as I've seen several people respond to the questions for this unit with the same problem... dead touchscreen.

I bought an HTC one X white 16GB in July 2012 from the AT&T store. I really liked the design and the screen and was very happy with my purchase.

Ever since February 2013 it has been showing this crippling malfunction - When I try to wake the phone from sleep mode, the screen does not activate. It stays off, while the three touch buttons at the bottom are illuminated as usual. The phone can receive calls, but the screen stays inactive for an indefinite period of time. Sometimes it comes back on, but its unpredictable when it does so.

In an emergency it would be a real problem if the screen just dies on me since there is no other way to make calls.

I'll try to do a factory reset and see if that helps soon. Otherwise this is an unreliable product - probably rushed to the market to compete with the S3

Good phone when it worked, but 2.5 months after the warranty ended, the touchscreen stopped registering touch in a rectangular area near the top of the screen.  Others online have reported the exact same problem with the hardware.  LG customer support refused to help us without an unknown service charge, or give a refurbished phone, so we are out of luck.  I was a big LG customer (stove, fridge, microwave, etc.), but this really turned me off to their products.

Original review (two updates follow):
I bought one of these in January 2011.  It worked great for the past 2.5 years, but is now developing problems (bad pixel colors for one of the two attached displays).  At $250 retail, I may have to write it off as an "$8.33 per month rental."  The most frustrating part of the problem is that I haven't been able to find documentation for the length of the product warranty -- everywhere I look seems to refer elsewhere.  I've sent an email to IOGEAR's support; if the unit is still in warranty I may be able to raise the star rating.

Update #1 - September 13, 2013:
IOGEAR's support was very responsive to my requests for info on the unit's warranty (which I found out was 3 years), and when I requested an RMA.  They shipped a replacement unit to me one or two days after they got the failing device.  Unfortunately, the replacement is as bad or worse than the original -- bad pixels show up as quickly, maybe sooner after boot-up, than they did before.  So, I'm now out the original price plus the postage that I paid for the warranty work.  Guess I'll try another brand / model of KVM for the replacement.

Update #2 - December 21, 2013:
Since September, I've replaced the video card that was displaying the green pixels.  I put the (RMA replacement) KVM back in the sequence and everything has been working fine again.  I can't explain why the problem surfaced after two and a half years (presumably something going bad in the video card), or why it only showed up -- intermittently -- when the KVM was in the sequence (i.e., no problems with the card wired direct to the monitor).

Started behaving erratically after two months, suspect poor quality unit.  Screen would spontaneously press buttons and close apps as if someone were touching it. Not software, reset did not fix.

Dead with infinite bootloops after 2 months. LG or the seller won't assist you.

I purchased two of these phones on May 9; the return policy expired June 12. About a week out of the return period, the first phone started malfunctioning. I can't get through a five minute phone call without the phone freezing, preventing any communication with the caller. The people on the other end of the line say they hear "running water" and garbled voices (not mine). This lasts anywhere from 3 - 45 seconds. It occurs sporadically and frequently. Often, we have to hang up and redial to get back to an actual phone conversation. I use the phone for business purposes, and can no longer speak with clients on this phone. I have freed up memory space and have more than 30M available, so that isn't the problem. The second phone started malfunctioning this week, too. Avoid this phone if you want to actually use your phone!
