There was a recent thread about this issue, although I cannot remember the final resolution. I hope you solve this problem!

i giynd the post and shared it in that one

Dryers should be on an outside wall for a short, straight shot exhausting to the outdoors. Every 90° turn effectively adds the equivalent of 5 feet. Check the installation requirements for the specific machine regards to the maximum allowed length ... the machine cannot properly push the airflow beyond that limit. Air velocity is what moves lint particles along to exit the system. The coiled spring structure of flexible ducting adds airflow resistance.

Even if the run is too long there should NOT be lint in the home if all of the joints in the vent pipe are properly sealed. If they are all sealed then the dryer is NOT sealed somewhere inside the cabinet. Many dryers are NOT sealed well internally. I have seen them with lint all over the inside of the cabinet. If your home has a negative pressure internally this can cause air to be pulled into the home through the vent hole and then through the dryer. This never used to be a problem, but many newer homes are so well sealed that it is very easy to create a negative pressure inside when a vent fan is running. This could be from a kitchen stove hood, bathroom vents, power vented gas heater, etc.

Just some things to think about. It would be weird to find lint all over the home though. We now have a Miele T1 dryer. That is a heat pump and is a sealed system so there is no air moving from inside the home to outside. All of the lint is trapped in the the lint filters.

As stated above a dryer should be vented directly outside if possible. The side of the dryer with the vent should be directly against an outside all with no turns or bends. Obviously this will not work for everyone, but it is the ideal. I have seen many new homes built with really bad venting. I have seen it vented UNDER the floor to an outside wall, multiple turns to where the mechanical run was over 50ft, which NO dryer will support. Most dryers are limited to 20 to 30 ft total run. Add 5ft for each 90 degree elbow as stated above.

Some lint does escape to the interior of the dryer. They should be disassembled and cleaned of lint accumulation every two years.

The machine interior is under negative pressure while the dryer is running ... it pulls air IN through grills or seams, over the heating element or gas burner, through the drum and filter and blower and out the exhaust ducting. There can be a bit of positive airflow into it when the dryer is not running, from outside air entering the exhaust ducting if the hood at the outdoor end doesn't have a good flapper/seal.

There are booster fans that can be installed inline with the exhaust ducting when long distances are involved. They of course require an electrical connection and have an airflow sensor that turns the fan on when the dryer is running, off when it isn't.

there is pretty good airflow outdoors thats why im confused about my dryer, its not even a year old, its hard to get a brush down inside cause of the turn inside my dryer, i think i will look into the booster fans mentioned above, thank you every one

The brand/model of dryer has not been stated. Dryer airflow is tricky to ascertain for someone who doesn't have experience with it. There should be some force behind it, similar to a hair dryer. Dryers typically need to move between 200 and 240 cubic feet of air per minute.
