H815T (china) bad built quality!

Hi all,

Long story short, after my H815 (Europe) bootlooped, I got a replacement mother board online which turned out to be a H815T (Hong Kong) model.

But after using a Samsung J7 as my phone for a while, I became a bit suspicious about the "superiority" of the LG flagship compared to other phones. And I started to raise questions about the poor performance of my beloved device. Because many aspects were not working quite at the level I was remembering them or I wanted them to be for ex.:

1. Call Quality
Every time I speak on the phone with someone they complain about the sound. They can not hear me, and ask me to raise my voice or get the phone close to my face. On the other hand sound recording works great, so I assume microphone is OK. (and YES! I checked the "Noise Suppression" setting for calls)

2. Bad Network Reception
Oh god, I can barley get enough reception for the phone to recognize the operator. I am forced to use the phone only on GSM network mode, because on LTE, I can get almost no network coverage even on flat buildings, let alone basements or elevators, on LTE very often phone would go to "emergency only" mode because It could get no reception at all. I live in Kosovo and network coverage is Excellent with my old H815 I had no issue at all, I also used to talk on the phone even at 2600m altitude in the mountains at the border far far away from any village or city with no problem at all.

3. Bad camera quality
Here I'm not so sure if it is just me or it is true. But photos from H815T look nothing special, maybe even not so good. Iphone 5SE and 6S pictures look way sharper and colorful compared to G4. And I remember I used to embarrass Iphones even DSLR's, but now I have no motivation to take pictures, as they look flat, and noisy even foggy sometimes. (cannot understand why since the camera sensor is not changed, I just swapped the mother board)

4. No 4K in youtube
This may just be app's fault, but I cannot watch 4K videos on youtube, however I can review 4K recordings from the phone camera. (this may be good for preventing heating of the processor)

5.Not so snappy performance
Gone are the good days of speed, I remember the time when my G4 was the king, not any more, laggy performance, often freezing, not so great ram management etc etc. The android version I use is 5.1 which I left for performance and heat issue. I can not be sure if it just me who is wanting a better performance or really the phone is not working as it should.

So besides point number 3,4 & 5 which are purely subjective and may vary from personal view or preference, and it is hard to truly prove any difference. I wanted to focus at points 1 & 2 which are really sections when the difference is very CLEAR and H815T performs very poorly compared to H815, and anyone can easy prove that since the effect is evident and obvious.

I wanted to ask If anyone one other than me is experiencing problems of this nature. And is it true that LG (like many other companies) make different quality products for different markets. And the phones sold in Europe are better than those sold in other countries (China in this case)?

Please feel free to give you opinion or add anything you might have noticed on this topic.

Stock Rom,
Yes I checked connections, because I had to remove the board quite often (but I'll give it another look)
One suggestions...Check the Chips that are on the Mainboard with them from Ifixit oder other teardown site.
Maybe they used different ones.

Other posibility is that H815T is not so Compatible with european frequences and parts.

The frequencies are compatible with Kosovo, and also I connect to network, but the reception is very bad.

There must be just two options, bad connection (antenna) or bad board quality. I'll check the antenna connection to main board again to remove any dubt.

Thank you for the your reply and help.

Very first thing you should check before tampering with the hardware is check your firmware. Try upgrading first.
