LCD replacement issues and sensitivity

Hi guys. I'm new in this community, and I'm writing here to ask for some help. I changed two displays on two different iPhone 5S, a black one and a white one. I did everything, except the isopropyl cleaning, with wrist bands to uncharge me. I noticed that both screens act weirdly. Both have washed out colors and writings, just like if the displays were not "retinas", so have a low resolution. And both of them need me to touch the whole body of the phone to work properly, otherwise they need more pressure than normal to sense my touches. If I use a rubber tip pen, the ones that can be used on trackpads or mobile displays, both of them do not recognize any touch. What can I do? Any help is appreciated.

Answer this question I have this problem too

Is this a good question?

Where did you buy the parts?

Here on iFix It. From the EU store.

First, double/triple check your install. Pay especially close attention to the display ribbon cables/connectors - clean them, inspect them for damage, and reseat them carefully and press firmly when you are sure the alignment is right. Second, if you have a known good display, install that and see if the problem persists. If the problem goes away, you may have gotten a bad batch of screens. I once received two bad screens in a row (rare, but it does happen). Good news is iFixit has a Lifetime Guarantee (see https://eustore.ifixit.com/en/Warranty/), and are very easy to work with.

Just triple check it isn't your install before returning the part.

I quadruple checked everything. This is the second black display and the third white one. All of them have this low sensitivity, not present in the two original ones I had to replace

Do you still have the two original ones? If so, put them back on, and see if the problem goes away. Or do you have a known good phone, what is called a gold unit in the repair business? If so, install the new displays on the gold unit and see if the screens have the same low sensitivity problem on the known good phone. Most repair shops will immediately put a new screen on a gold unit (sometimes called a test unit) to make sure they received a good part. The point is to eliminate variables.

Well the two old screens worked like charm. The problem is that I cannot refurbish them. The gold units are both phones, they worked 100% perfectly beforr cracking the glass and still works perfectly if I put them on. They have no sensibility issues

Brief update. I received a new white screen from iFixIt. Although the overall quality is still low (colors are too bright and the display looks not 1136 x 640 per 326 ppi) there is absolutely no sensitivity issue. I tested it without touching the phone, with light pressure and with the pen. It works perfectly. So, my assumption about some grounding problem in the previous displays is still the only explanation.

Consider getting screens from a different supplier, may not be ideal for your location but I recommend Mobile Sentrix, Mobile Defenders and Injured Gadjets.

A little update. Maybe a last update. I received the fourth black display. It had the same old sensitivity issue. Contacting the "support" enraged and really disappointed (you know, I need that screen, otherwise I wouldn't had bought it...) I talked about a trashy display (which is, being unusable). I received a childish answer, telling me that I won't receive any more "trash" by them. This behavior is unacceptable. I paid for a fully functional display and got 4 black displays and 3 white displays all with issues...

I'm posting a video of the issue. This is on the last display I tested. It has been the same on every display, except the last white one and the original black and white ones.
